I just had to resurrect this thread. I've been working with Cooper and his vet for about 2 months to figure out his odd licking behavior.
http://www.yorkietalk.com/forums/sic...hes-doing.html The only thing that I think it comes down to is peanut butter. He's been on an allergy diet for 2 months. I have to admit that i may have given him a peanut butter treat or 2 during that period. He seemed a little better but still showed symptoms of some kind of irritation.
He's back on regular food and he's been fine. To test, I gave him a treat that contains peanut butter this evening. He's doing the licking again.
I really don't know if it is the peanut butter, but at this point I have no other answers.
Thank you for the info in htis thread.
