I have a 9 mo old belgian malinois. He developed these “cold sore” like sores on the very tip of his tongue and has had them for a several weeks now. Red and white looking papules on tip of tongue. Firm to the touch and can be seen from the underside of his tongue as well. Some have the appearance of white heads. Has not been spreading, but is also not going away. Does not seem to be in pain, eating just fine and engaging in all activities as normal. We contacted our vet and they are unsure what this is. Will be going in to the vet again to take another look, but was wondering if anyone else has come across this before? Vet recommended taking all his rough chew toy away so he has only had access to his plush toys and blanket and does not seem to be getting better. We live on 5 acres of land and when he is running around will just randomly try and pull weeds from the ground, which may be causing some irritation. Any insight would be much appreciated.
