I recently got my pup from a friend of mine and moved into my new home. Unknown to us, the home was crawling with rodents who were infested with fleas. After 3 months of battling them we are finally rodent and flea free but my dog still has bald spots and is scratching constantly. Her vet said she had developed a skin infection from all the scratching and biting. She's very sensitive to fleas and had a horrible red swollen rash. We are using the antiseptic lotion the vet gave us for her rash, but she still has such dry skin and gets cuts, welts, and bald spots from all the scratching. Her hair feels dry too. Is there anything else we can do to help her with the dry irritated skin? The vet warned us that shepherds have very sensitive skin. I grew up with shepherds who were never given special food and they never had problems. She's my first all black shepherd and it seems her coat is much different then the shepherds I've grown up with. She doesn't really have an undercoat and her hair has always been thinner than theirs.
