My 10 year old lab has most symptoms for a yeast infection. Itchy rear end, chin, paws and ears. Have been to the vet and they prescribed some chlorhexidine spray. Did not seem to work. Wondering if anyone has had the same problem with yeast and their dog. If so, what did you do or supplement used to correct the problem? Has anyone fed an over the counter anti-yeast pill that women use for their dog? Any advice would be appreciated.
