Hi there and thanks for posting on Petco Pet Education Center, formerly Petcoach! If mites/mange have been ruled out by Solo's veterinarian, other causes may be related to a an allergy such as a food allergy or environmental allergy. A fungal infection could also be another potential possibility. Next steps would be to perform a fungal culture to rule out a fungal infection and be sure Solo is on a good quality flea preventative year round to help rule out a flea allergy. If fleas and fungus have been ruled out, then I would advise on getting an allergy test done on Solo. I hope this helps and thanks again for using Petco Pet Education Center, formerly Petcoach!

    There are several potential reasons for itching and red bumps, including fleas, mites, skin infections, and allergies. If you veterinarian did skin scrapings to rule out mites, I recommend treating Solo for fleas. Even if you don't see any, it only takes one flea to cause a reaction. https://www.petco.com/shop/en/petcostore/product/frontline-plus-for-dogs---red-for-dogs-89-to-132-lbs If that doesn't help you can try at itch soothing shampoo like these: https://www.petco.com/shop/en/petcostore/product/dog/dog-grooming-and-bathing/dog-shampoos-conditioners-sprays/burts-bees-for-dogs-itch-soothing-shampoo https://www.petco.com/shop/en/petcostore/product/dog/dog-grooming-and-bathing/dog-shampoos-conditioners-sprays/furminator-itch-relief-ultra-premium-dog-shampoo Thanks for using PetCoach.
