Hello,
I’m sorry to hear about your pup. No one online can diagnose or prescribe a treatment plan for your dog. If you are asking if you “can” well, sure. You can do whichever plan you chose for your dog. Is it going to be as effective as surgery? No one really knows. We think that surgery offers a faster recovery and a better long term prognosis overall. But which is best for you is a decision to be made after a long talk with a vet you trust. In almost all cases my clients choose conservative care because they simply can not afford the mri and surgery. I also strongly (strongly!!) recommend strict cage rest for 8 weeks. If your pup isn’t on your lap or outside going potty they are in a cage. Period. No excuses or exceptions. I say this so the scenario that your describe is less likely to happen. I hope this helps. I have tons of info on my blog and YouTube channel. Also the book below is super helpful.
Sorry for the late response. It sounds like you are doing everything recommended. It is difficult to keep them resting when they begin to feel better, but try to get him to rest as recommended. You could call your vet and let them know how he is doing and they may be able to advise you as to the next steps and what more you can do to help him.
