Birdie LouieBodacious Beef Jerky Treats

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.

Organ meat from the named animal, or unnamed when the label just says liver. Liver is one of the most nutrient-dense foods there is, rich in vitamin A, copper, iron and the B group, and most pets love the taste, which is why it is used both as an ingredient and as a flavor coating. For allergies, the species is what matters, and beef liver is beef. Unnamed liver can come from any species and may vary by batch.

A staple of grain-free recipes, supplying starch, fiber and plant protein. Peas were common in the diets examined in a federal investigation into heart disease in dogs; the investigation did not establish a cause and no ingredient was banned. Pea protein high on a list can inflate the protein number with a plant source. Pea allergy is rare. Not a problem, but worth noticing when it appears in several forms in one recipe.

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.
