Also known as: chicken meat, deboned chicken
Whole muscle meat from chicken — one of the most common and digestible proteins in dog food.
The skeletal muscle of the chicken, usually thighs, breasts, and trim. On a raw label this is fresh (~70% water) meat; on a kibble label 'chicken meal' is the same meat cooked down and dried to a concentrated powder.
Chicken is inexpensive, widely available, and dogs digest it well. It supplies complete protein (all 10 essential amino acids), B vitamins, phosphorus, and selenium.
Chicken has been part of the domestic dog's diet for thousands of years, but it only became the default pet-food protein in the 1980s when the North American poultry industry scaled up and trim became cheap enough to use in bulk. Before that, most commercial dog food was built on beef and grain by-products.
Cooked chicken bones splinter — never feed them. Raw poultry bones are soft and safe for most dogs when appropriately sized.
Canadian-raised, antibiotic-free, and human-grade chicken is the highest tier. 'Chicken by-product meal' is a lower grade (see its own entry).
Your dog has a diagnosed chicken protein intolerance or allergy.
A solid, digestible everyday protein. Quality depends entirely on which parts of the bird are used and how they're processed.
