To make a long story short, our 8ish year old dog has had a cyst on her shoulder for over a year. Took her to the vet and he confirmed that it was just a cyst and would cost 900 something to remove and it would probably just come back anyway, so we opted against surgery. 6 months later and the thing finally burst all over my kitchen, couch, livingroom floor....yeah yuck! Anyways. I have been cleaning it with peroxide daily & letting it "breathe" and then bandage it up with gauze pads and neosporin. Do I need to do anything else? It has been leaking, but doesn't seem to be infected.
