Query: Itchy dog

My dog has been suffering for the entire summer and fall with some nasty dermatitis. We have bathed her twice in the past two months with the Pine Tar Shampoo and have seen a remarkable improvement. Her skin has lost the inflamed look and the scalely patches are healing; she smells a whole lot better. Her coat is soft and shinning. Packers Pine Tar Soap products are oldies but goodies.
