My dogs got spots on his belly on one side of his penis. Some are red and some seem to have yellow heads, I have been away for a week and just got back, Im going to bath him tomorrow and make an appointment at the vets. Has anybody any idea what it is? I thought allergy but its only on one side of his belly. He had a little rash about 2 months ago and the vet gave him massive antibiotics saying it was a skin virus....... Can he keep getting "skin viruses"? if so how can I stop it? (sorry about the amount of questions its just these antibiotics cost me about £35 and I dont want to have to keep buying them if I can work out whats causing it)
