Top 10 Allergy-Support Dog Food Toppers
Detailed Product Reviews
1. 5 Element Food Therapy Allergy, Skin & Coat Support Dog and Cat Superfood Meal Topper – Add Water and Protein - Superfood Blend for Itchy Skin, Allergies & Shedding – Whole-Food Mix
Overview: The 5 Element Food Therapy topper takes a holistic, Eastern-medicine-inspired approach to pet nutrition, specifically targeting skin and coat health. This powder formula combines omega-3 rich sardines with antioxidant superfoods to address allergies and itching from the inside out, requiring you to add water and your own protein source.
What Makes It Stand Out: The food therapy philosophy sets this apart—it’s not just a supplement but a whole-food meal enhancement. The inclusion of wild-caught sardines provides bioavailable omega-3s, while organic ingredients like dandelion greens and goji berries offer unique phytonutrients rarely found in conventional toppers. The versatility to prepare as gravy or mix with meat adds practical value for picky eaters.
Value for Money: At $4.50 per ounce, this sits in the mid-range for specialty toppers. While not the cheapest option, the quality organic ingredients and vet formulation justify the cost. It’s more economical than prescription diets for skin issues and comparable to other holistic brands, though the need to add protein increases overall meal costs.
Strengths and Weaknesses: Strengths include the transparent, whole-food ingredient list, USA small-batch manufacturing, and dual preparation methods. The holistic approach appeals to owners seeking natural solutions. Weaknesses are the small package size (just 2 ounces), necessity of adding protein, and premium price point that strains multi-pet budgets. Some dogs may dislike the fish-forward flavor.
Bottom Line: This is an excellent choice for pet parents committed to holistic nutrition who want to address skin and coat issues naturally. Best suited for single-pet homes or as a rotational supplement rather than daily use for large dogs.

What Are Allergy-Support Topper Mixes?
Allergy-support topper mixes are specialized supplemental foods designed to be added to your pet’s regular kibble to address both palatability issues and allergic sensitivities simultaneously. Think of them as functional condiments—much like how a drizzle of olive oil and fresh herbs can elevate a simple dish for humans, these toppers transform basic dry food into a gourmet, therapeutic meal. They typically come in freeze-dried, dehydrated, or wet formulations and are crafted with limited, novel ingredients that minimize exposure to common allergens while delivering targeted nutrients that support skin health, digestive function, and immune system regulation.
What distinguishes these from standard toppers is their intentional formulation for sensitive systems. They’re not just about making food taste better; they’re about making food safer and more nourishing for pets prone to adverse food reactions. Most feature single-source proteins your pet has never encountered, eliminating the chicken, beef, or dairy that frequently trigger immune responses. They’re also fortified with omega fatty acids, probiotics, and prebiotic fibers that work synergistically to repair gut lining, reduce systemic inflammation, and restore the skin’s natural barrier—addressing the uncomfortable symptoms that make allergy sufferers miserable.
Why Kibble Alone Isn’t Enough for Allergy-Prone Pets
Standard kibble, even high-quality varieties, often falls short for pets battling food sensitivities. The manufacturing process itself—extruding ingredients at high temperatures—can alter protein structures, potentially creating new allergenic compounds that weren’t present in the raw ingredients. Additionally, most commercial kibbles rely on repetitive protein sources and contain multiple carbohydrate fillers, creating a perfect storm for pets with developing or existing allergies. When your pet eats the same protein daily for months or years, their immune system can start misidentifying these once-safe molecules as threats, triggering the cascade of itching, licking, and gastrointestinal distress you’re witnessing.
Beyond the allergy concerns, kibble’s low moisture content (typically under 10%) and uniform texture simply don’t excite many pets, especially those whose senses are dulled by chronic inflammation or medication. A pet experiencing allergic discomfort often has reduced appetite to begin with, and a bowl of dry, bland pellets does nothing to stimulate their interest. This creates a dangerous cycle: poor intake leads to nutritional deficiencies that further weaken the immune system, making allergic reactions more severe. Allergy-support toppers break this cycle by introducing novel, aromatic ingredients that entice eating while delivering therapeutic compounds directly where they’re needed most.
The Science Behind Food Allergies in Pets
Food allergies in dogs and cats are fundamentally immune system misfires. When a susceptible pet ingests a trigger protein, their body incorrectly identifies it as harmful and produces immunoglobulin E (IgE) antibodies. Subsequent exposures cause these antibodies to signal mast cells to release histamine and other inflammatory chemicals, resulting in the classic itching, redness, ear infections, and digestive upset we recognize as allergic symptoms. What many pet owners don’t realize is that the gut plays a starring role in this drama—approximately 70% of a pet’s immune system resides in their gastrointestinal tract.
Identifying Common Food Allergens
The usual suspects in pet food allergies are surprisingly limited. For dogs, the top offenders are chicken, beef, dairy, wheat, and egg. Cats share similar triggers, with fish and chicken leading the pack. These ingredients dominate commercial pet foods not because they’re inherently problematic, but because their overuse has created widespread sensitization. The concept of “exposure frequency” is critical here—proteins that appear most often in a pet’s diet are most likely to become allergens. This is why simply switching from one chicken-based kibble to another rarely solves the problem. The immune system needs genuinely novel proteins it hasn’t developed antibodies against, which is where exotic sources like kangaroo, rabbit, venison, or even insect protein enter the picture.
How Toppers Interrupt the Allergy Cycle
Allergy-support toppers work through several mechanisms. First, they reduce the overall allergen load by replacing a portion of the problematic kibble with hypoallergenic ingredients. Even if you can’t switch your pet’s primary food due to cost or prescription requirements, adding a novel protein topper dilutes the concentration of trigger foods. Second, many contain protease enzymes that help break down protein molecules into smaller, less allergenic peptides before the immune system can react. Third, ingredients like L-glutamine, marshmallow root, and slippery elm help repair the “leaky gut” phenomenon where damaged intestinal walls allow undigested proteins to enter the bloodstream, triggering systemic reactions. Finally, omega-3 fatty acids from sources like green-lipped mussel or algae oil actively suppress inflammatory pathways, providing symptomatic relief while the root cause is addressed.
Key Ingredients That Define Quality Allergy-Support Toppers
Not all toppers marketed for “sensitive” pets deliver on their promises. The ingredient panel tells the real story, and discerning pet parents should know exactly what to seek out. Premium formulations share common characteristics: minimal ingredient lists, purposeful nutrient inclusion, and transparent sourcing. They avoid the “kitchen sink” approach of throwing in dozens of trendy superfoods, instead focusing on a few well-researched components that genuinely support allergic pets.
Novel Protein Sources
The cornerstone of any effective allergy-support topper is a true novel protein—one your pet has never consumed. This requires careful dietary history tracking. If your dog has eaten chicken, beef, turkey, lamb, and fish, options like duck, rabbit, venison, kangaroo, or alligator may be appropriate. For cats, similar exotic proteins work, though their obligate carnivore status means they need higher protein concentrations. Hydrolyzed proteins represent another advanced option, where the protein molecules are enzymatically pre-digested into fragments too small for the immune system to recognize. While often more expensive, hydrolyzed toppers offer a safety net for pets with extensive allergy histories or those undergoing elimination diet trials where absolute certainty is crucial.
Limited Ingredient Philosophy
The “limited ingredient” label should mean more than just a short list—it indicates intentional simplicity. Each component should serve a specific purpose. Look for toppers with five to eight main ingredients maximum. Beyond the novel protein, you’ll typically find a single carbohydrate source like sweet potato, pumpkin, or tapioca (which are less allergenic than grains), a healthy fat source, and targeted supplements. This simplicity serves two purposes: it minimizes exposure to potential new allergens, and it makes identifying problematic ingredients much easier if reactions occur. Beware of toppers that claim “limited ingredient” but still contain multiple protein sources or vague terms like “meat meal” or “animal fat,” which obscure the actual contents.
Gut-Supporting Additives and Probiotics
The most sophisticated allergy-support toppers function as gut health interventions. They include specific probiotic strains with documented benefits for allergic pets, such as Lactobacillus rhamnosus GG or Bifidobacterium animalis. These beneficial bacteria help modulate immune response, strengthen intestinal barrier function, and outcompete pro-inflammatory microbes. Prebiotic fibers like chicory root or acacia fiber feed these good bacteria, while postbiotics (the beneficial metabolic byproducts of fermentation) provide immediate anti-inflammatory effects. Additional gut-healers include colostrum, which contains proline-rich polypeptides that regulate immune function, and digestive enzymes that ensure complete protein breakdown before absorption.
Ingredients to Avoid in Allergy-Support Toppers
Just as important as what’s included is what’s excluded. The pet food industry is rife with problematic ingredients that can undermine the very purpose of an allergy-support topper. Many manufacturers cut corners with cheap fillers or use marketing loopholes to include known irritants. A truly hypoallergenic topper should be free from these common culprits that can trigger or exacerbate reactions.
The Hidden Dangers of Fillers
Fillers like corn, wheat, soy, and unspecified “grain by-products” have no place in allergy-support formulations. These ingredients are not only common allergens themselves, but their high carbohydrate content can feed yeast overgrowth, which often accompanies allergic skin conditions. Potato starch, while grain-free, can still cause issues for some pets and offers minimal nutritional value. Cellulose powder, essentially wood pulp, is sometimes added as a fiber source but can irritate sensitive digestive systems. The best toppers use purposeful, whole-food carbohydrates like cooked pumpkin or sweet potato that provide fiber, vitamins, and moisture without inflammatory effects.
Artificial Additives That Trigger Reactions
Synthetic preservatives like BHA, BHT, and ethoxyquin are known to cause adverse reactions and should be immediate deal-breakers. Artificial colors serve no purpose beyond human marketing appeal and can be problematic—yes, that “cheese flavor” coloring might make the topper look appetizing to you, but it could worsen your pet’s symptoms. Even natural-sounding additives require scrutiny. “Natural flavor” is an ambiguous term that can hide allergenic proteins, and carrageenan, a common thickener in wet toppers, has been linked to gastrointestinal inflammation. Look for toppers preserved with mixed tocopherols (vitamin E) or rosemary extract, and avoid anything with unnecessary additives that don’t contribute to your pet’s health.
The Palatability Factor: Making Kibble Irresistible
Here’s where science meets artistry. Allergy-support toppers must accomplish the seemingly contradictory goals of being hypoallergenic and hyper-palatable. Manufacturers achieve this through understanding the biology of pet taste and smell. Dogs have about 1,700 taste buds compared to human’s 9,000, but their sense of smell is up to 100,000 times more acute. Cats are even more smell-dependent, with a highly developed vomeronasal organ for detecting pheromones and food odors. This means aroma is far more important than taste for both species.
Texture and Aroma Enhancement
Premium toppers manipulate texture and scent through gentle processing methods. Freeze-drying preserves the natural volatile compounds that create irresistible meaty aromas without introducing the Maillard reaction browning that can create new allergens. Dehydrated options rehydrate to create a gravy-like coating that clings to kibble, changing the mouthfeel and making each bite more satisfying. Some toppers include small amounts of palatants derived from hydrolyzed liver or fish—while these sound like “meat by-products,” they’re actually enzymatically broken down into amino acids that provide umami flavor without intact proteins that could trigger allergies. The result is a sensory experience that triggers your pet’s ancestral prey drive, making them enthusiastic about mealtime again.
Temperature and Moisture Tricks
Never underestimate the power of warming. Adding a topper with warm water (not hot) releases aromatic compounds and creates a temperature profile similar to fresh prey, which is naturally more appealing than room-temperature kibble. This simple step can increase intake by 30-40% in picky allergic pets. Moisture content is equally crucial. Many allergy symptoms cause mild dehydration, and pets instinctively seek water-rich foods. Toppers that create a light broth or gravy address this need while making kibble easier to chew and digest—especially beneficial for senior pets or those with dental issues that often accompany chronic health problems.
Choosing the Right Topper for Your Pet’s Specific Needs
One size does not fit all in the world of allergy management. The ideal topper depends on your pet’s species, age, size, and the severity of their allergic condition. A thoughtful matching process ensures you’re not just throwing money at the problem but investing in a solution that will genuinely improve your pet’s quality of life.
Dogs vs. Cats: Species-Specific Formulations
Canine and feline nutritional requirements differ dramatically. Dogs are omnivorous and can tolerate moderate carbohydrates, so dog-focused toppers might include beneficial fruits and vegetables like blueberries or spinach for antioxidant support. Cats, as obligate carnivores, require toppers with minimal plant matter and higher protein concentrations—ideally above 40% dry matter. Cat-specific toppers should also include taurine, an essential amino acid for heart and eye health that isn’t always necessary in dog formulas. Using a dog topper for a cat could lead to nutritional imbalances, while cat toppers are typically too rich and calorie-dense for dogs when used as directed.
Life Stage and Size Considerations
Puppies and kittens with allergies need toppers that support growth without overloading their developing systems. Look for formulations with controlled calcium and phosphorus levels, plus DHA for brain development. Senior pets benefit from toppers with added joint support like green-lipped mussel and turmeric, which also happens to be anti-inflammatory. Size matters too—small breed dogs need calorie-dense toppers in tiny portions to avoid weight gain, while giant breeds may require larger servings and specific ingredients that support slower metabolic rates. Many premium lines offer breed-size specific formulations that account for these metabolic differences.
Severity of Allergies: Matching Intensity to Formula
For pets with mild sensitivities (occasional itching, minor digestive upset), a basic novel protein topper with limited ingredients may suffice. Moderate cases benefit from added probiotics and omega-3s for active gut and skin healing. Severe allergies—characterized by chronic ear infections, self-mutilation from scratching, or inflammatory bowel disease—require the most advanced formulations with hydrolyzed proteins, medical-grade postbiotics, and potentially even serum-derived immunoglobulins that neutralize allergens in the gut. Understanding where your pet falls on this spectrum prevents under-treating serious conditions or over-treating mild ones unnecessarily.
DIY Allergy-Support Topper Recipes
Commercial toppers offer convenience and precision, but prepared pet parents can create effective homemade versions with proper knowledge. DIY approaches allow absolute control over ingredients and can be more economical for multi-pet households. However, they require careful attention to nutritional balance and food safety.
Simple Single-Ingredient Options
The safest starting point is a single-ingredient topper made from a novel protein your pet has never eaten. Boil rabbit, venison, or duck until fully cooked, reserve the broth, and finely shred the meat. Freeze in ice cube trays for easy portioning—one cube per meal is a good starting point for medium dogs. The reserved broth, chilled with fat skimmed off, can be poured over kibble for moisture and aroma. This approach is ideal for elimination diets because if reactions occur, you know exactly what caused them. Always introduce one new protein at a time and maintain for at least two weeks before adding another.
Balanced Homemade Blends
For longer-term use, create a more complete topper that addresses multiple needs. Combine 2 cups cooked and mashed sweet potato, 1 cup cooked novel protein, 2 tablespoons coconut oil, and a pinch of powdered egg shell for calcium. For added gut support, stir in a tablespoon of plain canned pumpkin (not pie filling) and a canine-specific probiotic capsule opened into the mix. This provides protein, moisture, fiber, healthy fats, and probiotics in one scoop. Store in the refrigerator for up to three days, or freeze in portions. Never include onions, garlic, grapes, raisins, or excessive salt, and consult with a veterinary nutritionist if you plan to replace more than 25% of your pet’s daily calories with homemade additions.
How to Properly Introduce Toppers to Your Pet’s Diet
Even the most hypoallergenic topper can cause digestive upset if introduced too quickly. A methodical approach prevents overwhelming your pet’s system and allows you to accurately monitor for both positive changes and adverse reactions. Patience during this phase pays dividends in long-term success.
The 7-Day Transition Protocol
Start on day one by adding just 10% of the topper’s recommended serving to your pet’s regular kibble. If your pet typically eats one cup of food, that’s about one tablespoon of topper mixed thoroughly. Observe stool quality, energy levels, and scratching behavior for 48 hours. If all remains stable, increase to 25% on day three. Continue this gradual escalation: 50% on day five, 75% on day seven, and full serving by day nine or ten. This slow ramp gives gut flora time to adjust and allows you to pinpoint any ingredient intolerance with precision. Keep a daily journal during this period noting appetite, stool consistency, skin condition, and behavior—this data becomes invaluable if you need to troubleshoot later.
Monitoring for Reactions
Know the difference between detox symptoms and true allergic reactions. Mild, temporary digestive changes like slightly softer stool can occur as the gut biome shifts and heals. However, increased itching, ear inflammation, vomiting, or diarrhea within 24 hours of a topper increase suggests a true intolerance. Take photos of your pet’s skin and ears before starting to create a visual baseline. Weigh your pet weekly—unexplained weight loss could indicate malabsorption issues. The “ear test” is particularly telling for dogs: if they start shaking their head or scratching ears within 12 hours of a new food, you’ve likely identified a problem ingredient. Stop the topper immediately and consult your veterinarian if severe symptoms develop.
Storage and Shelf Life Best Practices
Investing in premium toppers only to have them degrade through improper storage is a costly mistake. Different formulations require different handling, and understanding these nuances ensures your pet receives the full nutritional benefit you paid for.
Dry vs. Wet Toppers
Freeze-dried and dehydrated toppers are remarkably shelf-stable when unopened, typically lasting 12-18 months in a cool, dark pantry. Once opened, oxygen and moisture become enemies. Transfer contents to an airtight container, press out excess air, and use within 30 days. Add a food-grade desiccant packet to absorb humidity. Wet toppers in cans or pouches must be refrigerated after opening and used within 3-5 days. Never leave wet topper mixed with kibble at room temperature for more than two hours—bacterial growth can cause food poisoning, especially in immunocompromised allergic pets. For convenience, portion wet toppers into small silicone molds and freeze; they’ll thaw quickly when added to your pet’s bowl.
Refrigeration and Freezing Guidelines
If you prepare homemade toppers, proper storage is non-negotiable. Divide batches into single-serving portions immediately after cooking and cooling. Store three days’ worth in the refrigerator and freeze the remainder. Use glass containers rather than plastic to avoid chemical leaching, especially when storing acidic ingredients like pumpkin. Clearly label everything with the date and ingredients—what seems obvious today will be forgotten in three weeks. For freeze-dried toppers, paradoxically, freezing can extend shelf life after opening by preventing oxidation. If you buy in bulk, keep the main supply in the freezer and remove only a two-week portion at a time.
Cost Analysis: Are Premium Toppers Worth the Investment?
Sticker shock is common when first exploring allergy-support toppers. A 16-ounce bag might cost $25-40, significantly more than standard food toppers. However, a purely price-based analysis misses the bigger picture of health economics and quality of life improvements. Understanding the true cost per serving and potential long-term savings puts the investment in perspective.
Breaking Down the Price Per Serving
A typical freeze-dried topper recommends 2-4 tablespoons per cup of kibble. A 16-ounce bag contains roughly 60 tablespoons, meaning it provides 15-30 servings depending on your pet’s size. At $30 per bag, that’s $1-2 per meal. Compare this to the cost of prescription allergy medications like Apoquel ($2-4 per day) or Cytopoint injections ($50-150 monthly), and the topper becomes cost-effective preventive care. For pets requiring novel protein prescription diets at $90-120 per bag, using a quality topper with moderately priced limited-ingredient kibble can reduce total monthly food costs by 30-40% while achieving similar results.
Long-Term Health Savings
The real value emerges in avoided veterinary expenses. Chronic allergies lead to secondary skin infections requiring antibiotics ($50-200 per course), ear infections needing prescription drops ($30-80), and emergency vet visits for severe allergic flare-ups ($200-500). By managing symptoms nutritionally, many pet parents reduce these incidents by 60-80% annually. There’s also the incalculable value of your pet’s comfort—less itching means better sleep, reduced anxiety, and improved behavior. When framed as a daily investment in preventing $1,000+ annual allergy management costs, premium toppers deliver exceptional return on investment while providing the immeasurable benefit of a happier, healthier companion.
Frequently Asked Questions
How long does it take to see improvements in my pet’s allergy symptoms after starting a topper?
Most pet parents notice increased appetite and energy within 3-5 days, but visible skin improvements typically require 4-6 weeks of consistent use. This timeline reflects the skin’s natural renewal cycle—new, healthy cells need time to replace the damaged ones. Digestive symptoms like loose stool often improve within 1-2 weeks as gut flora rebalances. Keep a symptom diary to track subtle changes, and remember that seasonal environmental allergies can complicate results, so year-round feeding provides the clearest picture.
Can I use multiple allergy-support toppers at once for variety?
It’s best to establish your pet’s tolerance to one topper for at least 6-8 weeks before introducing a second. Once you know a single protein works well, you can rotate between 2-3 compatible toppers to prevent new sensitivities from developing. This rotational feeding mimics natural dietary variety but should be done systematically—never mix two new proteins in the same meal during the introduction phase, as this makes identifying triggers impossible if reactions occur.
My pet is on a prescription hydrolyzed protein diet. Can I still add a topper?
This requires veterinary approval. Some hydrolyzed diets are so precisely formulated that any addition compromises their effectiveness. However, many veterinarians approve single-ingredient hydrolyzed toppers or specific novel proteins that don’t interfere with the diet’s purpose. The key is ensuring the topper’s protein source is different from the hydrolyzed protein in the prescription food. Always consult the prescribing vet before adding anything, and consider that some prescription brands offer their own compatible toppers designed specifically for their diets.
Are freeze-dried raw toppers safe for pets with compromised immune systems from chronic allergies?
Freeze-drying reduces but doesn’t eliminate all pathogens. For severely immunocompromised pets or those on high-dose steroids or chemotherapy, fully cooked dehydrated toppers or wet formulations are safer. For most allergic pets not on immunosuppressive drugs, reputable freeze-dried options from companies with rigorous pathogen testing (HACCP certified) are generally safe. When in doubt, rehydrate freeze-dried toppers with hot water and let cool to reduce bacterial load further.
How do I know if my pet’s symptoms are from food allergies or environmental allergies?
True food allergies cause year-round symptoms that don’t fluctuate with seasons, while environmental allergies typically worsen during specific times (spring for pollen, fall for ragweed). Food-allergic pets often have both skin and digestive issues, whereas environmental allergies primarily affect skin. The most reliable method is an 8-12 week elimination diet using a novel protein topper and limited-ingredient kibble—if symptoms improve dramatically and then return when old food is reintroduced, you’ve identified a food component. Intradermal skin testing from a veterinary dermatologist can also differentiate the two.
Will my pet become dependent on toppers and refuse plain kibble?
It’s possible but preventable. Use toppers as a tool during the healing phase, then gradually reduce to 3-4 times weekly for maintenance rather than every meal. Rotate between topper-enhanced meals and plain kibble with just warm water. Think of it like seasoning your own food—you enjoy variety but can still appreciate a simple meal. The goal is long-term dietary flexibility that keeps your pet healthy without creating a picky eater who demands gourmet treatment at every feeding.
What’s the difference between a food allergy and a food intolerance, and do toppers help both?
Food allergies involve an immune response (IgE antibodies, histamine release) and typically cause skin issues like itching and ear infections. Food intolerances are non-immune digestive problems—think lactose intolerance causing diarrhea without skin symptoms. Toppers help both but in different ways. For intolerances, choose enzyme-fortified toppers that aid digestion of problematic compounds. For true allergies, novel proteins and immune-modulating ingredients are essential. Many pets have both, which is why comprehensive toppers address gut health alongside novel proteins.
Can puppies and kittens with allergies use adult-formulated toppers?
Puppies and kittens have specific nutritional requirements for growth that adult formulas may not meet, particularly regarding calcium-phosphorus ratios and calorie density. While a short-term trial (2-3 weeks) on an adult topper during an elimination diet is generally safe, long-term use requires a growth-appropriate formula. Some companies offer puppy/kitten-specific allergy toppers with added DHA and controlled mineral levels. When in doubt, consult a veterinary nutritionist to ensure the topper supports rather than compromises healthy development.
How do I transition my pet off an allergy-support topper if I need to switch to a prescription diet?
Reverse the introduction process gradually over 7-10 days, decreasing the topper by 10-15% every two days while increasing the new prescription food. Abrupt changes can cause digestive upset and food aversion. If your pet resists eating the new food without the topper, try using the topper’s broth or liquid portion only as a flavor enhancer during transition, gradually reducing this as well. Some pets may need a slower 14-day transition if they’ve been on the topper long-term.
Are there any breeds that respond particularly well or poorly to allergy-support toppers?
Breeds predisposed to food allergies—like Golden Retrievers, Labrador Retrievers, German Shepherds, Bulldogs, and West Highland White Terriers—often show dramatic improvements with toppers because their conditions are frequently diet-responsive. Conversely, some primitive breeds (Basenjis, Shiba Inus) may have more complex immune profiles and require longer trial periods. Giant breeds need careful calorie monitoring as some toppers are calorie-dense. Brachycephalic breeds (Pugs, French Bulldogs) with skin fold issues often benefit greatly from the anti-inflammatory omega-3s in quality toppers, which reduce the skin fold infections that plague these dogs.
