this it what the tic looks like, it is as if he is trying to remove something painful or annoying from his mouth. he opens his mouth and tries to scratch it away, he sometimes flicks his tongue out as if to remove something, this is now very regular, every day up to 6 times. Sometimes he uses both paws, as you can imagine this makes him stumble. My vet has checked him over, teeth all ok, tongue and inner mouth ok, no lumps or bumps and no complaints when head and neck region checked over. Ears also checked out ok. He eats and toilets normally. He is 13 so I wondered if this was just an old age thing and he has developed a weird habit. Which if so, fine, but I must say it is quite upsetting to see, cos it looks like he needs help. So do I, any thought or similar habits ? ?
