after calling my newf mentor in a teary-eyed, blubbering freakout upon discovery of Sulley's first hot spot, here is what worked for us.
I cut out the hair in the hot spot (like right down) and a little bit around it. I don't show my dog, so I can handle a bald spot. Kim said she would have thinned it with thinning shears, but same idea, and I was freaking out. You need to get some air in there so it can dry up.
I gave them each a good spray with Bactine twice a day for a few days, then applied gold bond (lightly) until they healed up and he left them alone.
A 'healthy' wound is whitie-pink, like when you scrape yourself or get a blister. If it is larger than the palm of your hand, REALLY smells, or is looking bad (like bad meat, darkesh looking or has puss), then it is probably time for a vet visit. Sulley's still smell a bit, although they are all healed up, so we are going to the vet this week to see what is going on.
