Allergic reactions are often triggered by allergens such as gluten and specific proteins. Thrive food is free from wheat, dairy, soy, and GM ingredients. Our products contain a single type of protein. This transparency allows you to easily identify any ingredients that your dog might be allergic to; we don't hide our ingredients under vague terms like "meat" or "animal derivatives." Because of this, Thrive foods are a popular choice for vets to use in exclusion diets when trying to determine which proteins a dog is allergic to. 100% irresistible, 0% Nonsense®
