Retriever Rescue

My beautiful boy from Jan has got a white lump on one of his droopy jowls at the back of his mouth, it doesn'nt seem to cause him any pain and he has only developed it today.
Does anyone know what it could be and does it need attention from the vet?

If you are worried about this then you must go to the vet.No-one on this site can tell you what it is without seeing it.

Let us know how you go on. it may just be an ulcer but you must find out
