About 4 weeks ago a few bumps showed up on Lewey. There was no itching and the vet said that it was atopic dermatitis because no mites were found on the skin scraping. We changed foods from Royal Canin Puppy to Hill's Prescription Diet Z/D ultra Allergen Free food and changed detergents. It seemed to get a little better until I left him with a friend who sat for me for 2 days. My friend bathed him in colloidal oatmeal shampoo (it had fragrance added to it) and he broke out everywhere. However, I just don't know if it was the shampoo because it never really cleared up completely to begin with. I took him back to vet who did a skin scraping again and indicated there were no mites that it was probably an allergic reaction. I thought maybe it looked like mange or something. It looks like small round patches of hair loss, it almost looks likes hives but when you lift the hair it looks like small pimples or something. He is itching every once in a while but not severe. He is playing normal and has no facial swelling. I am posting a few pics and wanted to know what you think it looks like, any advice is appreciated.
