Food Allergies

My pup may have possible food allergies, so I have to wean her off the chicken and beef, and give her lamb and fish food. Yes, my dog is now a guppy. She has had this rash that goes away briefly and then comes back. The vet said lets try modifying her diet. She also has to eat veggie treats, or nylon bones, anything but pigs ears, cow hide, and well anything that dogs tend to eat. Now I just have to convince my husband that he cannot feed her off the table. Maybe this will help. She was so sweet at the vet, I do not know what he did but, he relaxed her so much that she actually laid down on the table. She never does that. He was an older vet, so maybe he is well trained in calming dogs. I will keep you posted.
