I'm new to this board. I have an almost two year boy that licks and bites his paws. Three of his paws are saliva stained. He's only been with us for about 8 weeks ... rehomed from a breeder. The breeder said he had seasonal allergies. I posted a question on another board about this and Karlin suggested I read up on SM. I don't see any "air scratching" or pain around the neck area. Sometimes he seems to be trying to reach his back paw, his head between his front legs and his body looks curved under, shaking with some yelping. The first time I saw it I thought he was having a seizure. After this happens, his mouth seems to chatter and he licks his mouth. Could this be SM symptoms?
