We have a 10 month old mini blue dapple dachshund female. She has been spade and early sept she developed pimple like bumps on her head, down her back. They get scabby. She is loosing her hair and is itching. She has been to the vet and they think it maybe an allergy. We have changed her food, our laundry soap, her treats to no avail. We have given her anti-itch meds and cleaning her with med shampoos. Can anyone give me any helpful ideas. The vet is not much help. They have sold us expensive foods and shampoos but nothing seems to help. Please help us to get our beautiful puppy healthy again.
