Poultry can include meats like chicken, one of the most common food allergens for dogs, as well as options like a duck which has lower incidences of allergic reactions. Food allergies can cause distressing skin conditions in canines as well as chronic disorders such as indigestion, ear infections, and breathing troubles. Allergies are due to an abnormally high defensive response to a protein, in this case, a type of poultry, which the immune system perceives as an intrusive substance. Foods are broken down into amino acids by the digestive system, and the amino acids are then absorbed by enterocytes, a type of white blood cell. If the digestive system doesn’t completely break down the proteins, the enterocytes see them as intruders and attack the body.
An allergy to poultry is an over-reaction of your dog’s immune system to an unwelcome protein, in this case, a poultry protein, that is present in a particular ingredient of their diet.
