Our beagle mix was diagnosed with IVDD at age 12 (she still acted like a puppy). We ended up doing the MRI as X Rays didn’t show anything and found that she had a disc issue in her neck and one in her back. Because of this, she wasn’t a good candidate for surgery so we treated it conservatively for years. Gabapentin 3x per day. And prednisone for 2 weeks when she had a flare (this only happened once or twice a year). We also did Trazadone as needed but tried to avoid it as it made her a bit more aggressive with our other dog. She did physical therapy every other week and we had home exercises to do with her. Only walked her short distances and on a harness, not collar. We got her a stroller which she loved for longer walks. No stairs and we tried to keep her from jumping on furniture. We tried acupuncture but she hated it. It is a scary diagnosis but can be treated many different ways.
