I have a bald (the black hair anyway) 5mo old puppy given to me by my nephew after a bad breakup. Can't get any background info on breeding deficiencies. I suspect depressed immune system due to poor breeding practices, even though his conformation is great. Vet bills are killing me! Switched his diet to duck and potato, been on antibiotics for secondary staph (bumps that are ongoing after treatment) and have him on ivomec for possible demodectic mange. Wits end coming right up. HELP!
