Hello. I recently discovered a hollow ring-shaped red mark on my dog's abdomen. It's not raised and doesn't appear to be bothering him (it's not tender and he's not itching it). He has a loss of appetite and is a bit lethargic. Any help you can provide is most appreciated.
Again, because he is showing symptoms of illness, you need to have this checked out ASAP....Both are treatable, but will get worse quickly, without treatment......Karla
