Well Bentley my rescue I have had for about 2 1/2 months now has been itching like crazy for about 1 1/2 now & is poping up with hot spots...... He has a fungal skin infection which seems to be clearing up with the meds & shampoo that the vet gave me. He goes back Wednesday for his second round of heartworm treatment & I am going to ask about the itching & chewing (hot spots) to see maybe if its an allergy, but in the mean time I want to make him comfortable. Has anyone giving benadryl to there dogs to help with itching? I just want to use it until Wednesday when we go to the vet.
