KasiksMini Trainers Beef with Blueberry Treats - FirstMate Pet Foods

A red-meat protein, higher in fat and iron than poultry. Fresh or deboned beef is mostly water and ranks higher on the label than its dry contribution; beef meal is the concentrated form. Beef is among the most common food allergens reported in both dogs and cats, probably because it has been fed so widely for so long. Beef by-products such as liver and heart are listed separately.

The dried cells of yeast, often a by-product of brewing. It is rich in B vitamins, protein and minerals, improves flavor, and contains compounds that may support gut bacteria. Despite a persistent myth, there is no evidence it repels fleas. Yeast is an uncommon allergen in pets. Yeast culture is a slightly different product, a fermented feed that supplies similar nutrients.

Rendered fat, a concentrated energy source and the main supply of linoleic acid, an essential fatty acid for skin and coat. Rendered fat carries very little protein, so many chicken-allergic pets tolerate it, but not all do, and a strict elimination diet avoids it. Usually preserved with mixed tocopherols. Not a quality concern; a good fat source.

A fruit added in small amounts for antioxidants and a bit of fiber. Blueberries are safe for dogs and cats, and the pigments that color them are the same ones linked to antioxidant activity in people. In a complete food they appear well down the list in small amounts, so they are a modest extra and should not decide which bag you buy.

Almost always rosemary extract, used as a natural antioxidant to keep fats fresh, usually alongside mixed tocopherols. The amounts are tiny. A persistent internet claim links rosemary to seizures in dogs; there is no published evidence for it at food levels. If your dog has epilepsy, ask your neurologist rather than avoiding foods on this basis alone.
