What is this raw spot with pus and a black center on my dog's leg?

I found this raw round circle on my dog's hind leg tonight. He has been acting normal in personality and appetite. It looks like maybe there is a small puss pocket with a black speck in the middle.

I would worry that is a precious bite wound from a spider or something or a tumor or cyst that is infected and has a necrotic center. Try to stop in from licking it and clean it with soap and water to rinse the pus off. You can place neosporin to help prevent bacteria and dirt from getting inside. This will buy you time to get to your vet for further testing to see if surgery is needed or just antibiotics
