Understanding Colostrum and Canine Immune Health
What Is Colostrum?
Colostrum is the nutrient-dense, antibody-rich “first milk” produced by mammals in the initial 24-48 hours after giving birth. This isn’t ordinary milk—it’s a concentrated biological package containing immunoglobulins (antibodies), growth factors, lactoferrin, proline-rich polypeptides (PRPs), and essential nutrients. For newborn puppies, colostrum is literally life-saving, providing passive immunity until their own immune systems mature. For adult dogs, particularly those with compromised immunity, bovine colostrum (sourced from cows) offers similar bioactive compounds that can help modulate and support immune function.
How Colostrum Supports Immune Function
The magic of colostrum lies in its multi-pronged approach to immune support. PRPs act as immune modulators, essentially teaching an overactive immune system to calm down or an underactive one to ramp up—critical for dogs with autoimmune conditions or those on immunosuppressive medications. Immunoglobulins directly bind to pathogens, preventing them from colonizing the gut. Lactoferrin starves harmful bacteria of iron while supporting beneficial flora. For immune-suppressed dogs, this means potential protection against opportunistic infections, improved gut barrier function (where 70% of immunity resides), and reduced inflammatory responses that can further tax their system.
Recognizing Immune Suppression in Dogs
Immune suppression isn’t always obvious until a secondary issue appears. Dogs may be immunocompromised due to genetic conditions, chronic diseases like diabetes or Cushing’s, cancer treatments, long-term steroid use, or simply advanced age. Warning signs include recurrent infections (ear, skin, urinary), slow wound healing, persistent diarrhea, lethargy, and increased susceptibility to parasites. If your dog fits this profile, every dietary addition—including treats—should be viewed through an immune-support lens. Colostrum treats aren’t a cure, but they can be a valuable component of a comprehensive management plan.
Why Treats Matter for Immune-Suppressed Dogs
The Psychological Benefits of Treat-Giving
Eliminating treats entirely from an immune-suppressed dog’s life might seem safer, but this approach overlooks the profound psychological impact. Treats facilitate bonding, provide mental stimulation, enable training for cooperative care (essential for medicating or vet visits), and maintain quality of life. A dog undergoing daily medication regimens or frequent veterinary procedures deserves moments of joy. The key is transforming these moments from potential risks into therapeutic opportunities. Colostrum treats allow you to preserve the ritual of treat-giving while actively supporting their fragile health.
Nutritional Supplementation Through Functional Treats
Traditional treats can constitute up to 10% of a dog’s daily caloric intake. For immune-suppressed dogs, that’s 10% of their diet that could either burden their system with fillers and allergens or actively contribute to their wellness protocol. Functional treats like colostrum biscuits repurpose this caloric allotment into a delivery system for bioactive compounds. This is particularly valuable for dogs who resist powders or liquids mixed into food. The crunchy format ensures consistent dosing and palatability, turning a necessary supplement into a coveted reward.
Key Ingredients to Look for Beyond Colostrum
Novel Proteins for Sensitive Systems
Immune-suppressed dogs often develop new protein sensitivities, making novel protein sources crucial. While chicken and beef are common allergens, proteins like duck, rabbit, venison, or even insect protein provide essential amino acids with lower allergenic potential. When evaluating colostrum treats, examine the protein source carefully. A treat might boast premium colostrum but undermine its benefits with a reactive protein base. Single-source protein formulas with clearly identified meals (e.g., “duck meal” rather than “poultry meal”) offer transparency and reduce cross-contamination risks.
Anti-Inflammatory Additives
The best colostrum treats don’t stop at immune support—they address the inflammatory cascade that often accompanies immune dysfunction. Look for synergistic ingredients like turmeric (curcumin), omega-3 fatty acids from fish oil or algae, and blueberries. These compounds work alongside colostrum’s PRPs to reduce systemic inflammation without suppressing immunity. Avoid treats with added sugars or simple carbohydrates that can spike inflammation. The goal is a comprehensive anti-inflammatory profile, not just a single functional ingredient.
Gut-Supporting Probiotics and Prebiotics
Since colostrum’s immunoglobulins primarily work in the gut, supporting a healthy microbiome amplifies their effectiveness. Quality treats may include specific probiotic strains like Lactobacillus acidophilus or Bifidobacterium animalis with guaranteed colony-forming units (CFUs) through shelf life. Prebiotic fibers such as chicory root or pumpkin provide food for beneficial bacteria. This creates a symbiotic environment where colostrum’s bioactive compounds can function optimally, enhancing both gut integrity and immune response.
Decoding Quality: What Makes a Premium Colostrum Treat
Sourcing: The Gold Standard for Colostrum
Not all colostrum is created equal. The highest quality colostrum comes from pasture-raised, grass-fed dairy cows collected within the first 6-12 hours after calving. This “first milking” colostrum contains the highest concentration of immunoglobulins and PRPs. Ethical sourcing is equally important—reputable suppliers ensure calves receive adequate colostrum before any excess is collected for commercial use. Ask manufacturers for certificates of origin and collection timelines. Colostrum from cows raised without antibiotics, hormones, or pesticides prevents introducing new toxins to your already vulnerable dog.
Manufacturing Processes That Preserve Potency
Colostrum’s delicate proteins are easily destroyed by heat and improper processing. Look for treats made via cold-press extrusion or low-temperature baking (below 118°F). Some manufacturers use freeze-drying to preserve raw colostrum before incorporating it into treats. Avoid products that list “colostrum powder” without specifying processing methods—high-heat spray drying can denature up to 50% of immunoglobulins. The packaging should mention “minimal processing” or “bioactive preservation” to indicate attention to potency.
The Importance of Third-Party Testing
Reputable brands invest in independent laboratory testing to verify immunoglobulin content (IgG levels), screen for pathogens (salmonella, E. coli), and confirm absence of heavy metals and antibiotics. Request a Certificate of Analysis (COA) from any manufacturer. For immune-suppressed dogs, this isn’t optional—it’s essential. A COA should show specific IgG percentages (ideally 15-25% for bovine colostrum) and microbial testing results. Companies that hesitate to share this information should be immediately disqualified from consideration.
Texture and Formulation Considerations
Why Crunchy Biscuits Work Well
The crunchy texture serves multiple purposes beyond palatability. The mechanical action of chewing stimulates saliva production, which contains antimicrobial enzymes. The biscuit’s structure can also create a protective matrix that allows colostrum to survive stomach acid and reach the intestines intact, where it’s most needed. For dogs with compromised dental health (common in chronically ill dogs), crunchy treats can be crumbled over food, while those with healthy teeth benefit from the dental abrasion that reduces oral bacteria—an important consideration since oral infections pose serious risks to immunocompromised dogs.
Size Appropriateness for Different Breeds
Colostrum dosage isn’t one-size-fits-all. Small breeds need micro-biscuits (under 1 gram) to avoid over-supplementation and calorie overload. Large breeds require appropriately sized treats that deliver therapeutic doses without becoming choking hazards. Some manufacturers offer size-specific formulations with adjusted colostrum concentrations. For multi-dog households with varying sizes, consider easily breakable biscuits that allow precise portion control. The treat size should align with your dog’s weight class and daily colostrum target, typically 1/4 to 1 teaspoon of colostrum powder equivalent per 25 pounds of body weight.
Moisture Content and Shelf Stability
Immune-suppressed dogs can’t afford exposure to mold or rancid fats. Quality crunchy biscuits should have moisture content below 10% to prevent microbial growth. However, excessively dry treats may be unpalatable. The sweet spot is around 6-8% moisture with natural preservatives like mixed tocopherols (vitamin E) or rosemary extract. Vacuum-sealed packaging with oxygen absorbers maintains freshness. Once opened, treats should remain stable for at least 30 days if stored properly. Avoid soft or chewy colostrum treats, as higher moisture content increases contamination risk and often requires artificial preservatives.
Dietary Restrictions and Allergen Management
Grain-Free vs. Whole Grain Options
The grain-free debate requires nuance for immune-suppressed dogs. While some dogs genuinely benefit from grain-free formulations (especially those with grain sensitivities or certain autoimmune conditions), whole grains like oats or brown rice can provide beneficial beta-glucans that support immune function. The key is identifying the specific carbohydrate source and its quality. Ancient grains like quinoa or millet offer protein and fiber with lower glycemic impact. Avoid treats with corn, wheat, or soy—these are common allergens and often genetically modified, potentially introducing new sensitivities. The decision should be based on your dog’s known sensitivities and your vet’s recommendations, not marketing trends.
Limited Ingredient Diets for Maximum Safety
For immune-suppressed dogs, simplicity equals safety. Limited ingredient treats contain fewer components, reducing the chance of adverse reactions. The ideal formula includes: a single novel protein, one or two digestible carbohydrates, colostrum, and essential vitamins/minerals. Each ingredient should serve a purpose. Be wary of “limited ingredient” claims that still list 15+ items. True limited ingredient treats typically have 8-10 components maximum. This simplicity also makes it easier to identify the culprit if your dog does react negatively.
Avoiding Common Triggers and Fillers
Scrutinize ingredient lists for hidden immune stressors. “Natural flavors” is a vague term that can conceal allergenic proteins. Artificial colors (even “approved” ones) offer no benefit and potential harm. BHA, BHT, and ethoxyquin are chemical preservatives linked to health concerns. By-products and unnamed meat meals indicate lower quality control and potential for contamination. For immune-suppressed dogs, every ingredient should be identifiable, purposeful, and of human-grade quality. The “no” list should include: carrageenan, propylene glycol, menadione (synthetic vitamin K), and any ingredient you can’t pronounce or research easily.
Understanding Labels and Certifications
Reading Between the Marketing Lines
“Made with colostrum” could mean 1% or 30% colostrum content. Look for specific inclusion rates or guaranteed analysis of immunoglobulins. “Veterinarian recommended” is unregulated—any vet could recommend it, but that doesn’t indicate universal endorsement. “Human-grade” means ingredients meet human food standards, but the facility might not. “Organic” is valuable but must be certified by a recognized body (USDA, for example). The most reliable phrase is “complete and balanced” for treats meant to supplement, though this is rare. Focus on transparency over buzzwords.
Certifications That Actually Matter
For immune-suppressed dogs, certain certifications provide real assurance. USDA Organic ensures no pesticides or GMOs. NASC (National Animal Supplement Council) seal indicates adherence to quality standards for supplements. GMP (Good Manufacturing Practice) certification means the facility follows human pharmaceutical-level production controls. For colostrum specifically, look for DIRPA (Dietary Supplement Current Good Manufacturing Practice) compliance. Some manufacturers pursue Leaping Bunny certification for cruelty-free practices, ensuring ethical colostrum collection. These third-party validations matter far more than a company’s own claims.
Red Flags on Ingredient Lists
Learn to spot problematic patterns. Ingredients listed in order of predominance—if colostrum appears near the end, the dosage is likely subtherapeutic. Generic terms like “meat meal” or “animal fat” indicate poor quality control. Multiple carbohydrate sources (potato, tapioca, pea flour) suggest cost-cutting rather than nutritional strategy. “Digest” is a chemically hydrolyzed protein that can be highly allergenic. If a treat contains both colostrum (immune-stimulating) and high levels of omega-6 oils (inflammatory), the formulation lacks coherence. The ingredient list should tell a logical story of immune support.
Dosage and Frequency Guidelines
Working Within Daily Caloric Limits
Treats should never exceed 10% of daily calories, but for immune-suppressed dogs on strict diets, even this may be too much. Calculate your dog’s daily caloric needs based on ideal body weight and activity level, then determine the treat allowance. A typical colostrum biscuit contains 10-30 calories. If your dog requires 500 calories daily, that’s 50 calories max for treats—perhaps 2-3 small biscuits. Some colostrum treats are calorie-dense; factor this into meal planning to prevent weight gain, which further stresses the immune system. Work with your vet to adjust main meal portions accordingly.
Establishing a Therapeutic Routine
Consistency matters more than occasional high doses. Colostrum’s PRPs work best with steady, daily exposure. Divide the daily colostrum target into 2-3 treats given at strategic times: morning with medication (to buffer stomach upset), midday for enrichment, and evening to support overnight healing. Avoid giving all treats at once, which can overwhelm absorption. For dogs on immunosuppressive drugs like steroids or chemotherapy, coordinate timing with your vet—some evidence suggests giving colostrum 2-3 hours apart from certain medications prevents interference with drug metabolism.
When More Isn’t Better
Colostrum is powerful but not without limits. Excessive amounts can cause digestive upset or, theoretically, overstimulate certain immune pathways. Stick to recommended dosages based on weight. If using treats as the sole colostrum source, ensure the total daily amount aligns with therapeutic ranges (typically 1-2 grams of actual colostrum per 25 pounds). More treats mean more calories and potential allergens. If your dog needs higher colostrum doses for specific conditions like leaky gut or autoimmune disease, treats should supplement, not replace, a measured colostrum powder added to food.
Potential Interactions and Precautions
Medication Interactions to Discuss with Your Vet
Colostrum can interact with certain medications. Its immune-modulating effects may theoretically counteract immunosuppressive drugs like cyclosporine or azathioprine, though research is limited. It may enhance absorption of some antibiotics, which could be beneficial or require dosage adjustment. Dogs on blood thinners should use caution with high-dose colostrum due to its mild antithrombotic properties. Always provide your vet with the treat’s complete ingredient list and intended dosage. A two-week trial period with close monitoring is prudent when starting any new supplement in a medicated dog.
Over-Supplementation Risks
Colostrum treats are often part of a broader supplement regimen. Calculate total colostrum intake from all sources—treats, powders, and any combination products. Over-supplementation rarely causes toxicity but can lead to loose stools, gas, or reduced appetite. More concerning is the financial waste and potential for neglecting other nutritional needs. Immune-suppressed dogs require balanced nutrition, not just immune boosters. Ensure treats don’t displace essential nutrients from their main diet. Rotate functional ingredients to provide broad-spectrum support rather than megadosing on one component.
Signs of Adverse Reactions
Even with premium products, immune-suppressed dogs can react unexpectedly. Monitor for: increased itching or skin irritation (possible protein sensitivity), vomiting or diarrhea (intolerance or contamination), increased thirst or urination (stress response), or behavioral changes. Reactions may appear immediately or after 3-5 days of cumulative exposure. Keep a daily log of treat introduction, noting stool quality, energy levels, and any physical changes. If reactions occur, discontinue immediately and consult your vet. Have a backup plan—freeze-dried single-ingredient treats—to avoid abrupt cessation of positive reinforcement.
Integrating Treats Into a Holistic Care Plan
Coordinating with Prescription Diets
Many immune-suppressed dogs eat therapeutic diets like hydrolyzed protein, novel protein, or kidney support formulas. Colostrum treats must complement, not contradict, these diets. For example, if your dog eats a hydrolyzed diet for food allergies, any treat containing intact proteins could trigger reactions. In such cases, look for colostrum treats made with the same hydrolyzed protein as the prescription diet, or use pure colostrum powder exclusively. Some veterinary therapeutic brands now offer compatible functional treats—ask your vet about prescription-strength colostrum biscuits designed to work with their dietary protocol.
The Role of Treats in Training and Enrichment
Immune suppression often means increased confinement (avoiding dog parks, reducing exposure) and more medical procedures. Training and enrichment become vital for mental health. Use colostrum treats for low-stress handling exercises, puzzle feeder rewards, and calm behavior reinforcement during medication time. This transforms necessary restrictions into positive experiences. The act of working for a treat (snuffle mats, puzzle toys) provides cognitive engagement that reduces stress hormones, indirectly supporting immune function. Choose small, low-calorie colostrum treats specifically for training to allow multiple rewards without overfeeding.
Tracking Your Dog’s Response
Objective measurement helps justify the investment and guides adjustments. Create a simple scoring system: rate energy (1-10), stool quality (using a 1-7 scale), skin/coat condition, and infection frequency. Take weekly photos to track subtle changes. Note any reductions in medication side effects—some owners report improved appetite and energy when adding colostrum to steroid protocols. Share this data with your vet quarterly. Positive trends may allow for cautious treat dosage increases; negative trends warrant immediate reevaluation. This scientific approach treats treats as legitimate therapy, not just indulgences.
Storage and Handling Best Practices
Maintaining Colostrum Integrity
Colostrum’s bioactive proteins degrade with heat, light, and oxygen exposure. Store treats in their original, opaque packaging with the zip closure tightly sealed. If the package includes an oxygen absorber, don’t discard it. Keep treats in a cool, dry place—ideally under 70°F. Refrigeration can extend potency but may affect texture; if refrigerating, use an airtight container to prevent moisture absorption. Never freeze and thaw repeatedly, as ice crystals damage protein structures. Write the opening date on the package and adhere to the “use within X days of opening” guideline strictly.
Preventing Contamination in Immunocompromised Homes
Your dog’s compromised immunity extends to their environment. Wash hands thoroughly before handling treats. Use dedicated treat containers that are washed weekly in hot, soapy water. Don’t allow family members to grab treats from the bag—pour into a clean dish instead. Keep treats away from raw food preparation areas. If you crumble treats over food, use a clean utensil each time. For multi-pet households, store immune-support treats separately to prevent cross-contamination from other animals’ mouths. These precautions may seem excessive, but for a neutropenic dog (low white blood cell count), they can be life-saving.
Shelf Life and Freshness Indicators
Quality colostrum treats typically have a 12-18 month shelf life unopened. Once opened, use within 30-60 days maximum. Signs of degradation include: faded color, rancid smell (especially if containing fish oils), softening texture, or visible mold. If treats smell “off” or your dog suddenly refuses them, trust their instincts—dogs can detect rancidity we might miss. Don’t buy in bulk unless you can use them within the freshness window. Subscribe-and-save services may deliver more product than you can use safely. Calculate monthly usage and purchase accordingly, prioritizing freshness over cost savings.
Cost Considerations and Value Assessment
Why Premium Ingredients Cost More
True first-milking colostrum is expensive to source—producers must collect it during a narrow window and process it immediately. Pasture-raised, organic dairy operations have higher overhead. Third-party testing adds cost but ensures safety. Low-priced colostrum treats often indicate: late-collection colostrum (lower IgG content), heat-damaged proteins, or minimal inclusion rates. For immune-suppressed dogs, ineffective treats aren’t just a waste of money—they’re a missed therapeutic opportunity. Budget $30-60 for a month’s supply of quality colostrum treats for a medium-sized dog. This is comparable to many prescription medications and offers preventive value.
Calculating Cost-Per-Serving
Don’t compare bag prices—compare cost-per-effective-dose. A $40 bag with 30 high-potency treats delivering therapeutic colostrum levels may be better value than a $20 bag requiring 6 treats daily to achieve the same dose. Calculate: (Bag Price) ÷ (Number of Treats) ÷ (Colostrum mg per Treat) = Cost per mg of colostrum. Also consider calorie cost—if cheap treats require you to reduce main meals significantly, you might be compromising overall nutrition. Factor in the cost of potential vet visits from reactions to low-quality ingredients. True value includes safety, efficacy, and peace of mind.
Avoiding False Economy
Bulk buying, discount brands, or treats with vague colostrum sourcing might save money short-term but risk your dog’s health. Immune-suppressed dogs have zero tolerance for contamination or ineffective products. One infection hospitalization costs thousands, dwarfing any treat savings. Invest in quality and consistency. If budget is constrained, consider using fewer high-quality treats daily supplemented with homemade single-ingredient rewards (like baked sweet potato) rather than compromising on colostrum quality. Some manufacturers offer assistance programs for dogs with chronic conditions—it’s worth asking.
The Science Behind Colostrum Absorption
Bioavailability in Canine Digestive Systems
Dogs have a relatively short digestive tract compared to humans, meaning less time for nutrient absorption. Colostrum’s bioavailability depends on surviving stomach acid and proteolytic enzymes. Quality treats use enteric-coating principles—binding colostrum in a matrix of fiber and fat that delays gastric breakdown. The crunchy texture encourages slower chewing, mixing colostrum with saliva’s protective proteins. Research shows that colostrum immunoglobulins can remain intact in canine intestines for 6-8 hours, providing extended passive immunity. However, absorption rates vary based on gut health—dogs with inflammatory bowel disease may need higher doses or specialized delivery systems.
Timing and Administration for Optimal Effect
For maximum benefit, give colostrum treats on an empty stomach or 30 minutes before meals. This reduces competition with other proteins and allows PRPs to interact directly with gut-associated lymphoid tissue (GALT). For dogs prone to nausea, pair with a small amount of plain pumpkin or a probiotic treat. If using treats for medication delivery, give the treat first, wait 10 minutes, then administer medication—this ensures colostrum absorption isn’t compromised by drug compounds. For dogs receiving colostrum powder separately, time treats to provide a “booster” dose midday, maintaining steady blood levels of immune factors.
Working With Your Veterinary Team
Questions to Ask Your Vet
Before purchasing any colostrum treat, schedule a consultation. Ask: “Given my dog’s specific condition and medications, is colostrum appropriate?” “What IgG dose should we target daily?” “Should we monitor specific blood values while using colostrum?” “Are there any contraindications with my dog’s current treatment plan?” “How will we measure effectiveness?” Bring product information sheets to the appointment. A vet familiar with integrative medicine can provide dosing guidance, while a conventional vet can at least identify potential interactions. Don’t be discouraged if your vet is skeptical—ask for their specific concerns and address them with product data.
When to Seek Specialist Input
For complex cases—dogs with multiple autoimmune diseases, those on chemotherapy, or breeds with genetic immune deficiencies—consider consulting a veterinary immunologist or holistic veterinarian. These specialists can provide advanced protocols, such as pulsing colostrum (on for 5 days, off for 2) to prevent tolerance, or combining colostrum with specific Chinese herbs for synergistic effects. They may also recommend therapeutic blood levels of colostrum components that require precise dosing beyond what treats alone can provide. The additional consultation fee ($150-300) is worthwhile for dogs with severe immune compromise.
Creating a Collaborative Treatment Approach
Position yourself as the primary care coordinator. Keep a shared document with your vet team detailing all supplements, treats, and medications with dosages and timing. Update it monthly with observations. This prevents contradictory advice and ensures everyone works from the same information. If you see positive results, share them—veterinary medicine evolves through case observations. Your experience could inform future recommendations for other immune-suppressed dogs. The best outcomes occur when conventional medicine, quality nutrition, and targeted supplementation work in concert, with you as the informed advocate.
Frequently Asked Questions
Is colostrum safe for all immune-suppressed dogs?
While generally well-tolerated, colostrum isn’t appropriate for every immune-compromised dog. Dogs with severe dairy allergies, those on high-dose immunosuppressants for organ transplants, or dogs with certain types of lymphoma should avoid colostrum unless specifically approved by their veterinary oncologist or immunologist. Always start with a vet consultation and small test dose.
How long before I see results from colostrum treats?
Most owners notice subtle improvements in energy and stool quality within 2-3 weeks. More significant changes, like reduced infection frequency or improved skin condition, typically appear after 6-8 weeks of consistent use. The key is daily administration and realistic expectations—colostrum supports immune function but doesn’t replace necessary medications.
Can I give my dog colostrum treats with their medications?
Generally yes, but timing matters. Give colostrum treats at least 2 hours apart from immunosuppressive drugs like cyclosporine or chemotherapy agents to avoid potential interference. They can be given with most antibiotics and steroids. Always confirm with your vet, and never adjust medication doses based on treat supplementation.
What’s the difference between colostrum treats and colostrum powder supplements?
Treats offer convenience and palatability but contain lower colostrum concentrations due to space limitations and other ingredients. Powders provide precise, higher dosing for therapeutic needs. For immune-suppressed dogs, treats work best for maintenance support and training, while powders may be necessary for active disease management. Many owners use both strategically.
Are there any side effects I should watch for?
Mild digestive upset (looser stools, gas) can occur during the first week as the gut microbiome adjusts. Rarely, dogs may develop increased itchiness if sensitive to dairy proteins. More concerning would be signs of infection or worsening symptoms, which would warrant immediate discontinuation and veterinary evaluation. Most dogs experience no adverse effects.
How do I know if my dog is truly immune-suppressed?
Diagnosis requires veterinary testing, including complete blood counts (CBC) showing low white blood cell counts, specific immunoglobulin level testing, or response patterns to infections. If your dog experiences more than 3-4 infections yearly, has slow-healing wounds, or shows chronic low-grade illness, ask your vet about immune function testing before starting supplements.
Can puppies have colostrum treats?
Puppies over 8 weeks old can benefit from colostrum treats, especially those not receiving adequate maternal colostrum or facing early-life stressors. However, puppies have different nutritional needs and more sensitive systems. Use treats specifically formulated for puppies with lower colostrum concentrations and always under veterinary guidance. Never replace mother’s milk or formula with treats.
Should I choose grain-free colostrum treats?
Only if your dog has a diagnosed grain sensitivity or is on a grain-free prescription diet. Whole grains provide beneficial fiber and nutrients for many dogs. The focus should be on grain quality—organic, non-GMO sources—rather than absence. Some grain-free treats substitute with high-glycemic starches that may increase inflammation, defeating colostrum’s purpose.
How many colostrum treats can I give per day?
This depends on the treat’s colostrum concentration and your dog’s weight. Generally, 1-3 treats daily for small dogs, 2-4 for medium dogs, and 3-5 for large dogs, ensuring the total doesn’t exceed 10% of daily calories. Calculate based on the product’s guaranteed IgG content to reach your vet’s recommended dose, which is typically 1-2 grams of colostrum per 25 pounds of body weight.
What if my dog doesn’t like the taste of colostrum treats?
Quality colostrum has a mild, slightly sweet taste most dogs accept. If yours refuses, try crumbling a small amount over a favorite food to acclimate them. Some dogs prefer the taste when treats are briefly warmed (10 seconds in microwave) to release aroma. If refusal persists, the product may be rancid or low-quality. Return it and try a different brand, or switch to a flavor-masked colostrum powder mixed into palatable foods like plain yogurt or pumpkin puree.
