As per your symptoms of rashes on the on multiple body parts which seems to be due to contact dermatitis. Yes it could be due to fur allergy. Need not worry. I would suggest you to consult dermatologist without any delay. Because such symptoms can sometimes lead to severe allergic reactions. Doctor will treat your symptoms and may prescribe some anti-inflammatory medications. You should avoid touching or pricking these rashes. Apply cold compresses on skin. Apply calamine to soothe any kind of itching. Hope your concern has been resolved. Best Wishes, </s>
