Crunchy Biscuits With Duck Treats

Potato is commonly used in pet foods as a digestible carbohydrate source and functional binder, supplying starch, fiber, and modest amounts of vitamins (B6, C) and potassium—often included as cooked or dehydrated flakes, starch, or protein concentrates. While it provides energy and helps formulate grain‑free recipes, potatoes are not a primary protein for dogs or cats (and are not nutritionally required for obligate‑carnivore cats), can contribute to excess calories or affect blood glucose in diabetic animals, and must be cooked and free of green skins or sprouts to avoid solanine toxicity; allergies are uncommon but possible.

Duck is used in pet food primarily as a flavorful animal protein and fat source, commonly included in limited-ingredient or novel-protein formulas for dogs and cats. It supplies high-quality amino acids and energy and can help pets with sensitivities to common proteins, but it is relatively rich in fat (so may be unsuitable for low‑fat or pancreatitis-prone animals), can still trigger allergies in some pets, and requires proper cooking/processing and handling to avoid bacterial contamination.

Cane molasses is a viscous sweetener and palatability enhancer used in pet foods and treats to add simple carbohydrates, help bind ingredients, and contribute trace minerals like iron, calcium, potassium and magnesium along with small amounts of B vitamins. It can improve taste and texture but is high in sugars and calories, so it should be used sparingly—excessive intake can contribute to weight gain, dental issues, or unstable blood glucose in diabetic or obese pets.

Potato protein is a concentrated plant-based protein used in pet foods as a protein source, binder and texture enhancer, offering a highly digestible amino acid profile with relatively good lysine content compared with other plant proteins. It can be a useful hypoallergenic alternative for dogs and a supplement in balanced formulas, but it should not be the sole protein for obligate carnivores like cats because it lacks certain nutrients (e.g., sufficient taurine and other animal-derived factors) and must be used within complete, nutritionally formulated diets; quality processing also minimizes potato-specific compounds such as glycoalkaloids.

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.
