Strong Choice
A thoughtfully formulated daily supplement chew for adult dogs that avoids many of the most common food allergens while providing omega fatty acids and yeast culture to support skin and immune health. The peanut butter base can be appealing for dogs who can’t have chicken or beef. It should be used in addition to, not instead of, a complete and balanced dog food.

Benefits the manufacturer highlights in its own product marketing. KibbleLab lists them for reference and does not verify these claims.KibbleLab Review
Strengths
- Formulated to avoid many common food allergens like beef, dairy, wheat, lamb, egg, chicken, and soy, which can help sensitive dogs.
- Includes gamma-linolenic acid from borage oil plus EPA and DHA from fish oil to support skin and coat health.
- Contains yeast culture, a postbiotic, which can help support gut and immune function.
- Soft chew format with real peanut butter makes it easier to give as a daily supplement for most dogs.
Considerations
- This is a supplement, not a complete and balanced diet, so it must be fed alongside a regular dog food.
- Peanut butter may still be an issue for the rare dog with a peanut allergy or fat intolerance.
- Fish oil–derived EPA and DHA could be a concern for dogs with fish allergies.
- Dogs with pancreatitis or needing strict fat control should use any fat-containing chews only under veterinary guidance.

Top 5 Ingredients Explained
01
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.
02
Citric Acid
Citric acid is commonly used in pet foods as a preservative, pH adjuster and mild flavoring agent that helps inhibit microbial growth and chelate metals to slow fat oxidation and preserve color and freshness. It provides no nutritional value for dogs or cats and is generally safe at the low levels used in commercial diets, though concentrated forms or excessive intake can cause gastrointestinal upset or decreased palatability in sensitive animals.
03
Modified Food Starch
Modified food starch is commonly used in pet foods as a thickener, binder and texture stabilizer (in canned, pouch, and some dry formulas), supplying a digestible carbohydrate that helps maintain consistency and palatability. It provides calories but little protein or micronutrients, so it can contribute to excess energy intake in overweight or diabetic pets and may be a concern for animals with grain or starch sensitivities; modified forms are generally regarded as safe, though some owners prefer less-processed ingredients.
04
Glycerol
Glycerol (glycerin) is used in pet foods primarily as a humectant and sweetening agent to retain moisture, improve texture and palatability, and serve as a solvent or carrier in wet foods, treats, and liquid supplements. It provides a modest source of metabolizable energy for dogs and cats, but in large amounts can cause gastrointestinal upset and may affect blood glucose, so products intended for diabetic pets or sensitive animals should be used with caution.
05
Lecithin
Lecithin is commonly used in pet foods as an emulsifier and texture stabilizer—typically derived from soy, sunflower, or egg—and supplies phospholipids (such as phosphatidylcholine) that help disperse fats and maintain product consistency. In small amounts it contributes choline and supports fat digestion and cell membrane health, but it is not a primary nutrient source; soy-derived lecithin may be a consideration for pets with soy sensitivities and very high intakes can occasionally cause mild gastrointestinal upset.
