Every dachshund owner knows their dog is prone to spinal problems. We also know that we can help prevent back issues by not allowing them to jump off furniture or engage in heavy play with larger dogs. I don't have a lot to say on this subject other than get pet insurance for your winer dog and please don't let them jump off the furniture. If you must allow furniture access, build or buy doggie steps. Yes, they look awful, but so does this.
Below is my gal, Millie. She likes to sleep to tightly curled up that her tail wraps over her nose and the tip of it touches between her eyes. You can see her back is shaved; this is about 2 weeks post-op and that's as tight as she could curl up. It took her a long long time to regain that flexibility, among other things.
