so my dog has been having a chronic skin infection for about the past 2 years now, antibiotics would make it go away but it would always come back. Most recently i took him to the dog dermatologist, he was placed on this soy dog food thats quite expensive, and he has gotten much better. So supposedly he has a food allergy, possibly to beef or chicken or whatever. I agree with the food allergy, but have a hard time believing a dog is allergic to meat. I am thinking its more along the lines of whats in the dog food, or how the dog food is made, or any number of other ingredients.
