Can anyone help me out? My girl is almost 2 years old and I’ve been struggling with her skin for over a year now. We had fleas in the yard but that problem has professionally dealt with and haven’t had a flea for over 5 months, but she constantly itches, to the point where she makes herself bleed in places. She’s lost a fair bit of fur on the chest and stomach and is starting to get small red lumps on her ears (pic included). I have tried everything I can think of to help her, antihistamines and Prednisone from the vets only work temporarily, I bath her about 1 to 2 times a week with Malaseb shampoo which isn’t seem to be helping either, not sure if I should take her back to the vet or try something else? If anyone has some advice it would be really appreciated
