Hello. I am mom to two 3 yr.old Shischons...they are not related. My male dog itches ALL the time!!! He gets groomed regularly (every 5-6 wks) & has been on the same diet since we got him. I've taken him to the vet and discussed his non stop itching with the Dr. I was advised to give him a certain kind of Benadryl. I do not want to gave to do this all the time. Someone suggested Selsun Blue! I'm at my wit's end with the itching and feel very badly for him as well.
