Allergy & Immune Support Sensitive Care Peanut Butter Dog Supplement
Verified May 26, 2026
This is a soft chew dog supplement designed for adult dogs with food sensitivities who need extra support for skin, seasonal allergies, and immune health. It uses a peanut butter flavor base and avoids common protein allergens like beef, chicken, dairy, egg, lamb, wheat, and soy. Key active ingredients include GLA from borage oil and EPA/DHA from fish oil, along with yeast culture to support gut and immune function.
A thoughtfully designed allergy-focused supplement that avoids the most common food allergens while providing omega fatty acids and postbiotics to support skin, seasonal allergies, and immune function. It works best as a daily add-on for adult dogs who already eat a balanced diet but may benefit from extra skin and immune support. As with any supplement, it should be used alongside—not instead of—an appropriate complete and balanced dog food.

At a Glance
KibbleLab Review
Strengths
- Formulated without the major canine dietary allergens (beef, chicken, dairy, egg, lamb, wheat, soy), which is helpful for dogs with multiple protein or grain sensitivities.
- Includes GLA from borage oil plus EPA and DHA from fish oil, key fatty acids that can support skin barrier function and normal inflammatory responses.
- Contains yeast culture, a postbiotic ingredient that can support gut and immune health.
- Soft chew format with real peanut butter flavor is convenient for daily dosing and easier for most dogs to accept as a treat-like supplement.
Considerations
- This is a supplement, not a complete and balanced diet, so it must be given alongside a nutritionally complete dog food.
- Dogs with known fish allergies should avoid this product, as EPA and DHA are derived from fish oil.
- Peanut butter flavor is highly palatable but may not suit dogs with rare peanut sensitivities.
- As with any fat-containing supplement, very dogs prone to pancreatitis or on strict fat-restricted plans should only use it under veterinary guidance.

Top 5 Ingredients Explained
01
Yeast Culture
Yeast culture is a fermented yeast ingredient (commonly Saccharomyces cerevisiae) used in pet foods to provide natural flavors, B vitamins, amino acids and microbial metabolites that can support digestion, gut microbial balance, immune function and overall palatability. It is generally safe for dogs and cats, but animals with known yeast sensitivity or certain immune conditions may require caution and effects can vary depending on whether the product contains live organisms or dried yeast derivatives.
02
Gamma Linolenic Acid
Gamma-linolenic acid (GLA) is an omega‑6 fatty acid used in pet foods and supplements to support skin and coat health and for its potential anti‑inflammatory effects in managing dermatitis and allergic conditions in dogs and cats. It can help improve skin barrier function and reduce itching when supplied from sources like evening primrose, borage, or black currant seed oils, but should be balanced with omega‑3 fats to avoid pro‑inflammatory imbalance and may cause gastrointestinal upset or interact with anticoagulant medications, so use under veterinary guidance.
03
Eicosapentaenoic Acid
Eicosapentaenoic acid (EPA) is a long‑chain omega‑3 fatty acid commonly included in pet foods and supplements—usually from fish or algal oil—to provide anti‑inflammatory support for skin and coat health, joint comfort, and cardiovascular and immune function in dogs and cats. It is nutritionally important because pets (and especially cats, which convert plant omega‑3s poorly) benefit from preformed EPA/DHA, but owners should be mindful of product purity and oxidation and consult a veterinarian about appropriate dosing because high intakes can affect blood clotting or interact with certain medications.
04
Docosahexaenoic Acid
Docosahexaenoic acid (DHA) is a long-chain omega‑3 fatty acid added to pet foods and supplements to provide an essential lipid that supports brain and retinal development in puppies and kittens and helps maintain cognitive function, learning, and healthy skin and coat in adult dogs and cats. It is often supplied from fish or algal oils and is particularly important for species that convert plant omega‑3s poorly (e.g., cats); owners should be mindful of proper dosing, product oxidation or marine contaminants, and consult a veterinarian for animals on anticoagulant therapy or with specific health concerns.
05
Canola Oil
Canola oil is used in pet foods as a concentrated fat source and palatability enhancer that supplies energy and essential fatty acids—mainly omega‑6 (linoleic acid) and some omega‑3 (ALA)—and aids absorption of fat‑soluble vitamins. It can support skin and coat condition when balanced with animal fats or supplemental omega‑3s, but is calorie‑dense so must be portioned to avoid weight gain, does not provide species‑specific fats such as arachidonic acid for cats, and must be kept fresh to prevent oxidation.
