When we rescued our first puppy,
Travis, from a dirt road back in 1990, he was nearly starved to death, infested with worms, and both demodex and sarcoptic mange. He hardly had any hair anywhere, and the mange mites had about destroyed his hair follices. Of course, he had the attendant staph infection in his skin from the mites. Travis was about 6 weeks old when we found him, and the only treatment back then was the mitaban dips.
