Assessment

In veterinary dermatology literature and systematic reviews of canine cutaneous adverse food reactions (CAFR), beef is consistently established as the single most common dietary allergen in dogs (accounting for approximately 34% of cases). However, chicken ranks third overall (15%), behind dairy products (17%). While beef and chicken are the top two meat protein allergens responsible for canine food allergies, dairy ranks higher than chicken when considering all food allergens.

Mueller, Olivry, and Prélaud (BMC Veterinary Research, 2016) systematic review of 297 dogs with CAFR identified the leading allergens as beef (34%), dairy products (17%), chicken (15%), and wheat (13%).
MSD Veterinary Manual and subsequent veterinary literature (2018–2026) confirm beef, dairy, chicken, and wheat as the primary food allergens in dogs, with beef and chicken being the most common whole-meat triggers.
