My precious Sheltie mix was diagnosed with Dermyosititis. It started when she was about 3 months. I had no idea what could be wrong but with 3 wrong diagnosis I finally had the biopsy done. This was 6 months ago and we put her on the generic form of trentenal and it’s not working. my baby, Ramona, is miserable. She has hair loss all over but especially ears, face, feet and tail. It’s crusty and gooey. She’s only a year old and acts like she’s old. She has stopped playing and is constantly scratching. I have her on good food, vit e, fish oil, plus the meds. Prednisone did help but as soon as she went off it came right back. I’ve done all the research online, but feel I’m doing everything I can. Anyone have a pup with this? Anything would help. I’m afraid I’m going to loose her.
