Mugsy
My pug tends to do a weird bitting...almost chatter like thing with his mouth. I tend to see him doing this only when he's been smelling something (like the bed, couch, etc.) for a awhile. He'll then start to do that weird chattery thing until he starts to force excess liquid/saliva (i think it's saliva...) onto the object he is smelling. The smell almost smells like urine. What is he doing, and is this a sign of an infection??
