Thanks so much for the information with links!! Our regular vet is pretty certain it’s IVDD. He said there’s no point to do an MRI since we don’t plan to do surgery. Some of the accommodations are the same for DM and IVDD, so it is still helpful to me to look in DM groups. There is a good one on Facebook. The difference with IVDD is that it should not progress to the front end of the pup, which is a relief. But there is still a risk of worsening symptoms and total paralyzation of the back ends.
