Hi, My 15 month old german shepherd has this rash between his legs and its turning black and he lost his fur in that area. I also noticed he still pees with both of his legs down...is that normal? He also seems to walk alittle awkward, maybe due to the rash. I did take him to the vet and they gave me this shampoo to use called keto chlor and they told me to switch his food. I changed it to chicken soup because it didn't have all that wheat and wheat gluton. So far its been a month after the vet's visit and this issue is still going on. Anyone have this happen to their german shepherd and could give me some advise to help him?
