Hello everyone. This is Charlton. He is 2 and a half years old. We have been talking him to the vet for some time now because of the black spots on him. He has had them surgically removed twice and it's returning. Currently giving antibiotics. Biopsies revealed nothing twice. Does anyone know what this is, and if so how to treat it. Vet says it's bacterial but we have gone through several times of giving him shots.
Thanks
