Detailed Product Reviews
1. MB Herbals Apple Cider Vinegar Powder | 227G (8 oz/Half Pound) | 75 Servings | Spray Dried | Gluten Free | No Preservatives
Overview: MB Herbals Apple Cider Vinegar Powder delivers the tangy benefits of traditional ACV in a convenient, shelf-stable format. This 227-gram package provides approximately 75 servings of spray-dried vinegar sourced from apples grown in Himachal Pradesh at the foothills of the Himalayas. Designed for dual-purpose use, it dissolves easily in water for direct consumption or integrates seamlessly into culinary applications. The formulation maintains a clean label, free from preservatives and gluten, while using maltodextrin as a carrier to ensure consistent texture and solubility.
What Makes It Stand Out: The powder format eliminates liquid vinegar’s harsh acidity and pungent odor while preserving its tart flavor profile, making it significantly more palatable for daily consumption. Its versatility extends far beyond beverages into soups, marinades, sauces, and spice rubs without adding moisture. The Himalayan sourcing provides a compelling origin story that distinguishes it from conventional ACV products. Unlike pure powders that clump, the 10% maltodextrin content ensures reliable dissolution, while the compact packaging offers superior portability for travel or office use compared to bulky glass bottles.
Value for Money: Priced at $9.99 for 8 ounces ($1.25 per ounce), this powder commands a premium over liquid ACV but delivers justified value through convenience and stability. Each serving costs roughly $0.13, making it economical for regular users. The extended shelf life reduces waste from expired bottles, and the lightweight packaging saves on shipping costs. However, the 10% maltodextrin dilution means you’re receiving 90% pure ACV, which purists should factor into their cost-benefit analysis.
Strengths and Weaknesses: Strengths include exceptional convenience, versatile culinary integration, clean ingredient profile, Himalayan sourcing, and stable shelf life without refrigeration. The powder form is gentler on tooth enamel and digestive systems. Weaknesses involve the maltodextrin additive, which may deter those seeking 100% pure ACV. It likely lacks the beneficial “mother” culture found in raw, unfiltered liquid versions, and dissolution requires thorough stirring in cold liquids.
Bottom Line: This product excels for health-conscious consumers prioritizing convenience and versatility over maximum potency. Ideal for travelers, busy professionals, and culinary enthusiasts, it successfully bridges the gap between supplement and cooking ingredient. While not a complete replacement for raw ACV with the mother, it delivers solid value and functionality for everyday wellness routines.
The Antibiotic-Gut Health Connection in Dogs
Antibiotics are often non-negotiable when your dog faces a bacterial infection, but their impact extends far beyond the targeted pathogens. The canine gastrointestinal tract houses approximately 70% of the immune system within its complex microbial ecosystem. When antibiotics sweep through this delicate environment, they create a microbial vacuum that opportunistic pathogens are eager to fill. Understanding this connection is the first step toward proactive gut support.
How Antibiotics Disrupt Canine Microbiomes
Broad-spectrum antibiotics don’t just eliminate harmful bacteria—they indiscriminately wipe out beneficial strains like Lactobacillus and Bifidobacterium that regulate digestion, produce vitamins, and maintain intestinal barrier integrity. This disruption, known as dysbiosis, can manifest as diarrhea, reduced nutrient absorption, yeast overgrowth, and even behavioral changes linked to the gut-brain axis. The recovery period for a dog’s microbiome can span weeks to months without intervention, leaving your pet vulnerable to recurrent infections and chronic digestive issues.
The Ripple Effect: Beyond Digestive Issues
The consequences of antibiotic-induced gut imbalance extend well beyond loose stools. A compromised microbiome can trigger systemic inflammation, weaken immune responses, and affect your dog’s mood and energy levels through neurotransmitter production. Skin issues, food sensitivities, and increased susceptibility to parasites often trace back to a gut that never fully recovered from antibiotic treatment. This is why strategic gut support isn’t just beneficial—it’s essential.
What Are Dehydrated Apple Cider Vinegar Gut Health Cubes?
These specialized supplements represent a fusion of ancient wisdom and modern nutritional science. At their core, they’re precisely measured portions of raw, unfiltered apple cider vinegar that have undergone gentle dehydration to create shelf-stable, palatable cubes. This process concentrates the beneficial compounds while eliminating the harsh acidity and strong odor that make liquid ACV difficult to administer to dogs.
The Dehydration Advantage: Concentration Without Compromise
Low-temperature dehydration preserves the enzymatic activity and beneficial bacteria found in the “mother” of raw apple cider vinegar, unlike pasteurization which destroys these delicate compounds. The resulting cubes maintain a stable pH, consistent dosage, and enhanced bioavailability. This method also allows for the inclusion of heat-sensitive probiotic strains and prebiotic fibers that would be destroyed in baked treats or extruded kibble, creating a truly functional supplement rather than just a flavored snack.
Raw, Unfiltered ACV: The Gold Standard
The therapeutic value lies in the “mother”—those cloudy strands of proteins, enzymes, and friendly bacteria that commercial brands often filter out. For gut health cubes to be effective, they must start with organic, raw, unfiltered apple cider vinegar containing active acetic acid bacteria and yeast. This living component is what sets therapeutic-grade cubes apart from products using distilled or processed ACV, which offers little more than acidity.
Why Apple Cider Vinegar Matters for Canine Wellness
Apple cider vinegar’s reputation as a health tonic isn’t just folk medicine. Its unique composition addresses multiple aspects of gut health simultaneously, making it particularly valuable during antibiotic recovery. The synergy between its organic acids, enzymes, and microbial content creates a multi-pronged approach to healing.
The Mother Load: Enzymes, Probiotics, and Acetic Acid
The “mother” contains dozens of beneficial strains of bacteria and yeast that can help repopulate a depleted gut. Acetic acid, the primary active compound, creates an inhospitable environment for pathogenic bacteria while supporting the growth of beneficial microbes. Natural enzymes like amylase and protease aid in breaking down food when your dog’s own enzyme production is compromised by antibiotics, ensuring they still extract maximum nutrition from their meals.
pH Balance and Its Role in Gut Health
A dog’s digestive system requires specific pH ranges for optimal function. Antibiotics can disrupt this balance, making the intestines too alkaline and allowing harmful bacteria to thrive. ACV’s natural acidity helps restore proper pH levels in the stomach and upper GI tract, improving protein digestion and creating conditions where beneficial bacteria can flourish. This pH modulation also supports the integrity of the intestinal lining, preventing leaky gut syndrome.
Key Benefits for Dogs on Antibiotics
The strategic use of dehydrated ACV cubes during antibiotic treatment addresses the specific challenges your dog faces. These benefits work synergistically to minimize side effects and accelerate microbiome recovery, turning a potentially damaging treatment into a manageable, short-term disruption.
Restoring Microbial Balance Post-Antibiotics
The probiotic strains in quality cubes begin colonizing the gut immediately, competing with opportunistic pathogens for resources and attachment sites. The prebiotic fibers selectively feed these beneficial bacteria, giving them a competitive edge. This proactive approach can reduce recovery time from months to weeks, preventing the cascade of secondary issues that often follow antibiotic courses.
Supporting Digestive Enzyme Production
Antibiotics can damage the brush border enzymes in the small intestine, temporarily impairing your dog’s ability to digest carbohydrates and proteins. The natural enzymes in raw ACV provide temporary support while stimulating your dog’s own enzyme production. This is crucial for maintaining energy levels and muscle mass during illness and recovery, especially when appetite may be reduced.
Enhancing Nutrient Absorption During Recovery
A damaged gut lining absorbs nutrients inefficiently, meaning your dog might not benefit fully from even the highest-quality food. The butyric acid produced when ACV’s acetic acid is metabolized by gut bacteria helps repair intestinal cells. Combined with improved pH balance and enzyme activity, this ensures your dog extracts maximum nutrition from every meal during the critical recovery window.
Critical Ingredients to Look For
Not all gut health cubes deliver on their promises. The ingredient list reveals everything about a product’s efficacy. Knowing what belongs in a premium cube helps you identify formulations that will genuinely support your dog’s recovery rather than just providing expensive treats.
Probiotic Strains That Survive the Dehydration Process
Look for specific, researched strains like Bacillus coagulans, Lactobacillus acidophilus DDS-1, and Bifidobacterium animalis rather than generic “probiotic cultures.” Spore-forming bacteria like Bacillus species are particularly valuable as they survive dehydration, storage, and stomach acid to germinate in the intestines. The CFU count should be guaranteed through the end of shelf life, not just at manufacture, with at least 1 billion CFU per cube for therapeutic effect.
Prebiotic Fibers: Feeding the Good Bacteria
Quality cubes include diverse prebiotic sources like organic inulin from Jerusalem artichoke, fructooligosaccharides (FOS), and mannanoligosaccharides (MOS). These fibers resist digestion and ferment in the colon, producing short-chain fatty acids that nourish colonocytes. Avoid products that list vague “fiber sources” or rely solely on apple pectin, which provides limited prebiotic benefit. The ratio of prebiotics to probiotics should be balanced—too much prebiotic fiber can cause gas and bloating in a sensitive gut.
Organic Apples: The Foundation of Quality
The apples used should be organic and preferably include the peel, which contains quercetin and other polyphenols that act as antioxidants and prebiotics. Some premium formulations use specific apple varieties known for higher polyphenol content, like Red Delicious or Granny Smith. The dehydration process should preserve these compounds, which support the growth of beneficial bacteria while inhibiting pathogens.
Additional Gut-Soothing Compounds
Top-tier cubes often incorporate complementary ingredients like L-glutamine for intestinal repair, slippery elm bark for mucosal protection, and marshmallow root to reduce inflammation. These botanicals should be organic and properly extracted to ensure bioavailability. Some formulations include bovine colostrum for its immunoglobulins and growth factors, which can be particularly beneficial for dogs with compromised immunity during antibiotic treatment.
Red Flags: Ingredients to Avoid
The supplement industry isn’t tightly regulated, and many products marketed for gut health contain ingredients that can undermine your dog’s recovery. Learning to spot these problematic additives protects your investment and your dog’s health.
Artificial Preservatives and Fillers
BHA, BHT, and ethoxyquin have no place in gut health products, as they can disrupt microbial balance and have been linked to health concerns. Sodium benzoate and potassium sorbate, while natural, can inhibit beneficial bacteria growth. Quality cubes use natural preservation through proper dehydration and packaging, perhaps with mixed tocopherols (vitamin E) as a safe antioxidant. Fillers like wheat, corn, or soy not only dilute potency but can also feed yeast overgrowth in an imbalanced gut.
Added Sugars and Sweeteners
Many manufacturers add honey, maple syrup, or even cane sugar to mask ACV’s tartness, but sugar feeds the very pathogens you’re trying to eliminate. Even “natural” sweeteners can disrupt blood sugar and provide fuel for opportunistic yeast like Candida. The small amount of natural fruit sugars from apples is sufficient; any additional sweeteners indicate a poorly formulated product designed for palatability over efficacy.
Unnecessary Binders and Flavorings
Look out for artificial flavors, colors, and binding agents like propylene glycol or artificial gums. These additives can irritate an already sensitive gut and may trigger allergic reactions. Quality cubes achieve proper texture through natural pectin and careful dehydration techniques, not chemical binders. If you see ingredients you can’t pronounce or wouldn’t eat yourself, keep shopping.
Understanding Potency and Dosage
Effective dosing isn’t one-size-fits-all, especially when your dog’s system is compromised. The concentration of active ingredients determines whether you’re providing therapeutic support or just a tasty treat. Understanding potency metrics helps you calculate true value and avoid under-dosing.
The ACV Concentration Question: How Much Is Effective?
Therapeutic-grade cubes should contain the equivalent of at least 1 teaspoon of raw, unfiltered ACV per cube for a medium-sized dog. This provides approximately 500-750mg of acetic acid, the minimum needed for meaningful pH modulation and antimicrobial effects. Some manufacturers list ACV as a percentage of the cube’s weight—look for formulations where ACV represents at least 30% of the total composition. Anything less may not deliver sufficient active compounds.
Weight-Based Dosing Guidelines
Manufacturers should provide clear dosing charts based on weight ranges, not vague “one cube per day” instructions. A 10-pound dog needs significantly less than an 80-pound German Shepherd. Effective products offer graduated dosing: small dogs (under 25 lbs) might receive half a cube, medium dogs (25-60 lbs) one cube, and large dogs (over 60 lbs) two cubes. During active antibiotic treatment, some veterinarians recommend a slightly higher “loading dose” for the first week, then tapering to maintenance levels.
Adjusting for Antibiotic Strength and Duration
Broad-spectrum antibiotics like enrofloxacin or amoxicillin-clavulanate cause more severe dysbiosis than narrow-spectrum options. For aggressive antibiotic protocols, you might increase the frequency (e.g., one cube twice daily) rather than the individual dose. Long-term antibiotic courses (beyond 14 days) require sustained support, making cost-effective bulk purchasing important. Always coordinate dosing adjustments with your veterinarian, especially if your dog is on multiple medications.
Timing: When to Administer with Antibiotic Courses
Strategic timing maximizes benefits while preventing interactions. The relationship between ACV cubes and antibiotics requires careful scheduling to ensure both work effectively without interfering with each other.
The Two-Hour Rule: Separating ACV from Medications
Administer ACV cubes at least two hours apart from antibiotic doses. The acetic acid and antimicrobial compounds in ACV could theoretically bind to certain antibiotics, reducing absorption. More importantly, this separation ensures the probiotics in the cubes aren’t immediately killed by the antibiotic circulating in your dog’s system. Morning antibiotic with breakfast? Give the ACV cube as a midday treat or with dinner, maintaining that critical buffer zone.
Creating a Gut Support Schedule
For optimal results, begin ACV supplementation 24-48 hours before starting antibiotics if possible. This pre-loads the gut with beneficial bacteria and creates a more resilient microbiome. Continue daily throughout the antibiotic course and for at least two weeks afterward—many experts recommend extending support for a full month post-treatment to ensure complete microbiome restoration. Some dogs benefit from ongoing maintenance dosing, especially those with chronic GI sensitivity.
Quality Indicators and Manufacturing Standards
The supplement market’s lack of regulation means quality varies dramatically. Knowing how to assess manufacturing practices separates premium therapeutic products from marketing hype. These indicators often matter more than flashy packaging or celebrity endorsements.
Third-Party Testing and Certificates of Analysis
Reputable manufacturers provide Certificates of Analysis (COA) from independent labs for every batch. These documents verify CFU counts, acetic acid levels, and screen for contaminants like heavy metals, mycotoxins, and pathogenic bacteria. Look for testing that includes viability studies proving probiotics survive storage and stomach acid. Companies that post COAs publicly demonstrate transparency; those that refuse to share them likely have something to hide.
Human-Grade vs. Feed-Grade Ingredients
“Human-grade” means all ingredients and manufacturing processes meet FDA standards for human consumption. This matters because feed-grade ingredients can contain higher levels of contaminants and lower quality standards. While the term isn’t legally regulated for pet supplements, manufacturers using human-grade ingredients typically advertise it prominently. Ask direct questions: “Are your apples organic and human-grade?” “Is your facility USDA-inspected for human food production?”
Small-Batch Production Benefits
Large-scale manufacturing often involves high-heat processes and extended storage that degrade sensitive compounds. Small-batch production allows for fresher ingredients, gentler processing, and more quality control. Look for “small batch” language on packaging or websites, and check expiration dates—products with 18-24 month shelf lives likely contain more robust preservation systems than those expiring in 6 months, which may indicate minimal processing and fewer additives.
Palatability and Administration Tips
Even the most effective supplement fails if your dog refuses it. The dehydration process naturally concentrates flavors, but clever formulation and administration strategies can make the difference between enthusiastic acceptance and a daily battle.
Masking the Tang: Flavor Profiles Dogs Love
Quality manufacturers balance ACV’s acidity with natural palatants like organic chicken liver, bone broth powder, or nutritional yeast. These aren’t just flavorings—they provide additional nutrients. Some dogs prefer apple-cinnamon blends, while others respond better to savory profiles. If your dog is notoriously picky, look for single-ingredient cubes you can crumble over food rather than force-feed whole. The texture should be firm but not rock-hard, allowing easy breaking if needed.
Creative Serving Methods for Picky Eaters
For dogs who turn up their noses, try crumbling a cube into warm water to create a broth, then pouring it over kibble. The warmth releases aromas and softens the cube. You can also hide pieces in a Kong toy with peanut butter (xylitol-free) or mix with pumpkin puree. Some owners have success using the cubes as training rewards when broken into smaller pieces, creating positive associations. Never force-feed, as stress negates gut health benefits.
Cost Analysis and Value Assessment
Price tags can be misleading. A $40 container might seem expensive until you calculate cost per therapeutic dose. Understanding value metrics ensures you’re investing in efficacy, not just marketing.
Price Per Serving vs. Price Per Container
Divide the total cost by the number of servings based on your dog’s weight. A $50 container with 60 cubes might last a small dog 4 months but only 1 month for a large dog. Therapeutic-grade cubes typically cost $0.50-$1.50 per dose. Below this range, suspect quality; above it, you may be paying for branding. Factor in the cost of prevented vet visits for post-antibiotic diarrhea or yeast infections—these cubes often pay for themselves.
Subscription Models and Shelf Life Considerations
Many premium brands offer 15-20% discounts for subscriptions, which makes sense for long-term antibiotic courses or maintenance dosing. However, check shelf life first—ordering 6 months of cubes that expire in 3 months wastes money. Quality products maintain potency for 18-24 months when properly stored. Some companies offer flexible subscriptions that let you pause or adjust delivery schedules, preventing waste while ensuring you never run out during critical treatment periods.
Storage and Freshness Preservation
Dehydrated cubes are shelf-stable, but improper storage can degrade probiotics and enzymatic activity. Proper handling ensures you’re delivering full potency with every dose.
Proper Container Types and Conditions
Store cubes in their original airtight container, away from heat, moisture, and direct sunlight. The packaging should include a desiccant packet to control humidity—never remove it. Avoid transferring cubes to plastic bags, which can trap moisture. A cool, dark pantry is ideal; the refrigerator is unnecessary and can introduce condensation. Once opened, use within the timeframe specified on the label, typically 60-90 days for maximum potency.
Shelf Life Expectations for Dehydrated Products
Quality dehydrated ACV cubes maintain label potency for 18-24 months unopened. After opening, probiotic counts gradually decline—this is normal and why opened-container timelines matter. If cubes become soft, sticky, or change color, they’ve absorbed moisture and should be discarded. The acetic acid itself remains stable, but the living probiotics and enzymes are what you’re paying a premium for. Buying smaller containers more frequently ensures fresher product if you have a small dog.
Monitoring Your Dog’s Response
Every dog’s microbiome is unique, and responses to supplementation vary. Systematic observation helps you fine-tune dosing and identify whether the product is working or if adjustments are needed.
Positive Signs: What Improvement Looks Like
Within 3-5 days of starting ACV cubes, you should see firmer stools and reduced gas. By day 7-10, expect improved energy, better appetite, and less abdominal discomfort. The coat may appear shinier as nutrient absorption improves. Keep a simple log: stool consistency score (1-5), energy level, appetite percentage, and any GI symptoms. This objective data helps you and your vet assess progress and make informed decisions about continuing or modifying the protocol.
When to Pause or Adjust
If diarrhea worsens or your dog develops excessive gas or bloating, you may be dosing too high or the prebiotic fiber content may be too rich for their sensitive system. Reduce the dose by half for 3-4 days, then gradually increase. Some dogs experience a temporary “die-off” reaction as harmful bacteria are displaced—mild lethargy or loose stools for 24-48 hours can be normal. However, persistent symptoms beyond 72 hours warrant discontinuation and veterinary consultation.
Consulting Your Veterinarian: Essential Conversations
While ACV cubes are generally safe, professional guidance ensures they complement rather than complicate your dog’s treatment plan. Veterinarians increasingly recognize the importance of microbiome support during antibiotics.
Questions to Ask Before Starting
Bring the product’s ingredient list and COA to your vet appointment. Ask: “Are any of these ingredients contraindicated with my dog’s specific antibiotic?” “Should we adjust the timing based on my dog’s medication schedule?” “What specific improvements should I monitor?” For dogs with chronic conditions like kidney disease or diabetes, your vet may recommend modified dosing or specific formulations. Some antibiotics, like tetracyclines, have specific binding concerns that require longer separation times from supplements.
Integrating with Your Dog’s Treatment Plan
Your veterinarian can help create a comprehensive gut support protocol that might include ACV cubes, temporary diet modifications, and additional supplements like S. boulardii (a beneficial yeast that isn’t affected by antibiotics). They can also recommend follow-up testing, such as fecal microbiome analysis, to objectively measure recovery. This collaborative approach ensures you’re not just treating symptoms but actively rebuilding your dog’s gut health foundation.
Frequently Asked Questions
1. Can I give my dog ACV cubes while they’re still taking antibiotics, or should I wait until the course is finished?
You can and should start ACV cubes during antibiotic treatment, but timing is crucial. Administer the cubes at least two hours before or after the antibiotic dose to prevent the medication from killing the beneficial probiotics in the supplement. Starting 24-48 hours before antibiotics (if possible) can even help prepare the gut, and continuing for 2-4 weeks after completing antibiotics supports full microbiome recovery.
2. How do dehydrated ACV cubes compare to liquid apple cider vinegar mixed in my dog’s water?
Dehydrated cubes offer precise dosing, eliminate the strong taste and smell that many dogs reject, and preserve heat-sensitive probiotics that liquid ACV lacks. The dehydration process concentrates beneficial compounds while making administration mess-free and travel-friendly. Liquid ACV can also irritate tooth enamel and esophageal tissue if not properly diluted, risks that cubes eliminate.
3. Will these cubes interact with my dog’s other medications?
ACV cubes can potentially interact with certain medications beyond antibiotics, including diuretics and insulin, due to ACV’s effects on potassium levels and blood sugar. The two-hour rule generally applies to all medications. Always provide your veterinarian with the complete ingredient list and discuss potential interactions, especially if your dog is on multiple prescriptions or has chronic health conditions.
4. My dog has a sensitive stomach and reacts to new supplements. Should I still try ACV cubes?
Dogs with sensitive GI tracts often benefit most from ACV cubes, but introduce them gradually. Start with one-quarter of the recommended dose for 3-4 days, then slowly increase. Choose cubes with minimal ingredients—just ACV, a single probiotic strain, and one prebiotic fiber. Avoid formulas with multiple botanicals or complex ingredient lists that increase reaction risk. Monitor closely and discontinue if you see persistent vomiting or worsening diarrhea.
5. How long does it take to see improvements in my dog’s stool quality and energy levels?
Most dogs show improvement in stool consistency within 3-5 days, with energy and appetite improvements following within 7-10 days. However, dogs on long-term antibiotics may need 2-3 weeks for noticeable changes. If you see no improvement after 14 days, the product may be ineffective for your dog’s specific microbiome needs, or there may be underlying issues requiring veterinary attention.
6. Are there any dogs who shouldn’t take ACV gut health cubes?
Dogs with diagnosed kidney disease should use ACV products only under veterinary supervision due to potassium content. Dogs with known yeast overgrowth (systemic candidiasis) may need to avoid ACV temporarily, as the sugars in apples could theoretically feed yeast, though the acetic acid typically counteracts this. Puppies under 6 months and dogs with severe immunosuppression should also have veterinary clearance before starting any probiotic supplement.
7. What’s the difference between CFU count and viability, and why does it matter?
CFU (colony-forming units) measures the number of live bacteria at manufacture, while viability indicates how many survive storage, shelf life, and stomach acid to reach the intestines. A product with 5 billion CFU but poor viability may deliver fewer effective bacteria than one with 1 billion CFU and excellent viability. Look for brands that guarantee CFU through expiration and provide data on acid resistance and shelf-stability testing.
8. Can I use these cubes as a daily preventative, or only during antibiotic treatment?
Many dogs benefit from daily maintenance dosing, especially those with chronic digestive issues, food sensitivities, or who are prone to infections. Maintenance doses are typically half the therapeutic dose used during antibiotic treatment. However, some veterinarians recommend cycling—3 weeks on, 1 week off—to prevent the gut from becoming dependent on external probiotic support. Discuss long-term use with your vet based on your dog’s individual health profile.
9. How do I know if the probiotics in the cubes are actually alive when I give them to my dog?
You can’t visually confirm viability, which is why third-party testing and brand reputation are crucial. Reputable companies use opaque, airtight packaging with desiccants to protect probiotics from moisture and light. Some include “time-release” or enteric-coating technologies, though these are less common in cubes. If the product has been properly stored and is within expiration, and if you see positive changes in your dog’s digestion, the probiotics are likely alive and active.
10. My dog is on a prescription hydrolyzed protein diet. Will ACV cubes interfere with this therapeutic diet?
Quality ACV cubes without added proteins are generally compatible with hydrolyzed protein diets. However, some cubes include flavorings like chicken liver or bone broth, which could contain intact proteins. For dogs on elimination trials or hydrolyzed diets for inflammatory bowel disease, choose single-ingredient ACV cubes with no animal-based flavorings. Always confirm compatibility with the prescribing veterinarian, as even small amounts of non-hydrolyzed protein can affect diet trials.
