Buddy cut his forearm. Small lil cut, and it has been two days, he licks at it now and then. Now it seems to have small lump. It is Sunday, so I'll call vet tomorrow, but what SHOULD i have done? Hydrogen peroxide? Since it was so small, did not even bleed, i figured dog's licking the cut would keep it clean...? Craig wants to put bacitracin ointment on it and wrap it up so he can't lick it. Is that okay for dogs? What should we do?
