My dog's underbelly is black, dry, crusted, and he keeps licking it.

Pet's info: Dog | Mixed Breed | Male | unneutered | 2 years and 6 months old | 12 lbs

My dog has a seemingly large rash on his underbelly. His nipples are enlarged. The skin went from bright pink to dark black. It's super dry and almost "crusted" he is constantly licking his underbelly. I am unsure what this could be.

Oh my . Poor Maddox. So this appears to potentially be a severe yeast infection of his skin. He needs a skin cytology through your vet to confirm this and then likely will need a short course of anti-fungal pills a topical anti-fungal shampoo /- conditioner spray. I would recommend scheduling an app with your vet soon to get this taken care of, because nothing at home will be able to treat this successfully unfortunately. However, hopefully we can get this addressed quickly and successfully. I would also consider having your vet test Maddox for thyroid disease (as an underlying factor), especially if you have noticed any recent weight gain, dull haircoat /- lack of normal energy level. Best wishes with Maddox and his skin. Take care.
