My puppy is around 7 months and for a few weeks he has had a spot or two on his lower abdomen on the area where there is less fur. They are slightly raised oval or round areas. A couple of days ago he was licking them quite a lot but now less so so they aren't bothering him. They look dark but I wonder if this is mud stuck to them.
Any ideas what they could be? Some sort of skin parasite? Should I go to the vet or give it another couple of days to see if it improves alone?
