Soy allergies are an example of this — where the body treats the soy protein as an allergen
causing hypersensitive reactions resulting in itching, pruritus, and distress for your pet.
Many dogs are
hypersensitive to certain foods or ingredients including chicken, beef, fish, eggs, pork, turkey, milk, corn, wheat, whey, and preservatives, to name a few, which
cause them to suffer an allergic
reaction.
Some dogs may be
hypersensitive, thus their immune system may respond abnormally,
causing an allergic
reaction in different parts of the body, including the eye.
