Duck & Pear Freeze-Dried Treats

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.

Duck liver is an organ meat used in pet foods and treats as a concentrated protein and highly palatable micronutrient source, supplying bioavailable vitamins (notably vitamin A and B12), iron, and copper for both dogs and cats. It is nutrient-dense and beneficial in moderation but should be included as part of a balanced formula because excessive liver can lead to hypervitaminosis A and mineral imbalances, and it should be properly processed to minimize pathogen risk.

Pear is used in pet foods primarily for fiber, moisture and natural flavor, and can contribute vitamin C, vitamin K, potassium and antioxidant phytonutrients that support general health. It may help with digestive regularity and add low‑fat sweetness, but pears are relatively high in natural sugars and their seeds/core should be removed (seeds contain trace cyanogenic compounds), so use is best moderated—especially for overweight or diabetic dogs and cats.

Mixed tocopherols are a blend of natural vitamin E compounds (alpha, beta, gamma and delta tocopherols) used in pet foods primarily as a natural antioxidant and preservative to protect fats and fat‑soluble nutrients and extend shelf life. They also supply dietary vitamin E—an essential antioxidant for immune function, skin and coat health and cellular integrity in dogs and cats—and are generally safe at typical use levels, though they are not a substitute for a complete vitamin formulation and may be less effective in animals with fat‑absorption disorders.

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.
