Dopey, sounds like you received medical attention, but I would keep that wound unbound, open to the air, and as clean as possible until you're sure there's no infection. I've seen dog bites turn ugly including one fellow who developing sepsis from a tiny puncture that he bandaged.
Sorry this happened to you.
I've had so many doctors tell me to keep bandages on and that had only made things worse. When I was in college I had this mole on my shoulder removed because I was afraid it was cancerous (it wasn't) and he told me to keep the bandage there for three days. Day two I am doing some homework and I kept smelling this odd smell. It was driving me insane and I couldn't trace the source. It turns out it was my festering mole hole. I ripped that bandage off and scrubbed it in the shower. Now, any time I get a laceration by a doctor or something else I keep it open to the air and wash it well.
