We applied Hartz 3 in one to our 9-month old beagle a week ago. Now his hair is coming out and his skin is infected where I applied the drops. What do I do? He does not seem to be sick, just has a skin infection. It is gross looking and I know it is hurting him. After reading some of the posts, I just bathed him in Dawn. What about Benadryl?
