HillsSoft & Chewy Training Treats with Real Chicken Dog Treat

The most common protein in pet food, and for dogs one of the most common food allergens, with beef and dairy. If chicken is what your pet reacts to, it hides everywhere: chicken fat, chicken broth, chicken meal, natural flavor. On a label, chicken listed first is weighed with its water still in, so a food leading with fresh chicken often has less chicken protein than one leading with chicken meal. Neither is better; they are different measures.

A plant source of omega-3 fat (alpha-linolenic acid) and fiber, used in about a third of dog foods for coat and stool quality. Dogs and cats convert plant omega-3 to the useful forms inefficiently, so fish oil does the job better. Flax is not a documented common allergen, though some pets tolerate it poorly, most often as loose stool. Fine in a food; not a reason to prefer it over one using fish oil.

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.

The liver of the chicken, used both as a nutrient-dense ingredient and as a flavor. It is rich in vitamin A, iron, copper and B vitamins and most pets find it very palatable, which is why it turns up in treats and as a coating on kibble. Because it is chicken, it counts as chicken for a pet with a chicken allergy, even when it appears far down the list.

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.
