I am assuming that this is acne under Twinkie's chin b/c I noticed he has been scratching under his chin alot and I looked under it today just to see and OMG it was a big red circled scabbed area. He has been scratching at it and it is really scabbed, the size of 1/4 of a penny maybe bigger. I feel so bad that I let it get this far but any ideas on what it could be and more importantly how to get rid of it? Does this kind of thing eventually go away or do I need to go to a vet and get some cream for it? Thanks for any answers to this. <<))
