My dog was diagnosed with allergies. She has been on an elimination diet for 2 months and still has itchy, red skin on forearms and chest. She wears a collar with a metal buckle and the rash is especially bad on her chest where the buckle and tags hang. Could she have a metal allergy? We have bought her a new collar today, minus the metal and only put it on when she goes out. Allergies are year round. The only thing that helps is steroids which are not good for her. What is the next step we should take? She also has a raised, pimple (boil?) on her neck. Since she went back to her old food, she is lethargic, vomiting bile and has no appetite. This has only been two days however.
