My older Cocker girl spends a lot of time licking her Vulva, at first I thought it might have been a gland issue but she has had the done twice , she is still doing it and I have noticed a brownish stain on the white towel she was sat on, I cant decide if it is just something in the hair in that area (she is very hairy) although she has been bathed and trimmed , but that shouldnt cause the constant licking, as anyone any suggestions what it could be , I have read about a few possibilities most for bitches that arent spayed . She was done as a pup and is nearly 12 now, ....
