ok..i couldn't stand the sad look on Dookie's face so i brought him to the vet. after she cleaned the wound, we realized that it was much bigger than we thought. turns out, the skin was clipped off and the muscle/tissue is now exposed. the patch is about the size of a quarter and that's quite big on a 5.5 lbs dog!! it's also a little infected...it's quite gross.
anyway, she suggested that we clean the wound 2 times a day and give him antibiotics and stuff for the pain. if it doesn't start healing in a few days, he'll need to go under and have the extra skin cut off, and stiched back together.
i took the bill to the groomers and they paid the whole thing and apologized some more. even though i'm sure it was an honest mistake, i'm NEVER going back there again!
