My dog was just diagnosed with IVDD. He had The wobbly sailor legs. We are on day 6 of “crate rest” and my husband and I noticed that his Back end almost looks skinnier? Could he be losing muscle mass this soon and is muscle loss even a side effect? His back and doesn’t seem as droopy from when I brought him in on Saturday his legs still kind of cross in the back and he is not strong. I have anxiety, diagnosed, and so I’m just looking for some peace of mind. We could just be over thinking it and maybe his backend always was the size.
