My yorkie is losing hair on his head- he is 14 months- took to vet yesterday and he has been scratching alot and she feels it is an allergy- so he is to start taking 12.5 mg or teaspoon of benadryl every day- if anyone can suggest any other treatments I would be grateful.. He is totally a inside dog and in the summer he is on frontline-- no carpet, wood floors in all the house. THanks for all your help
