So sorry Seko / Helene -
Is a collapsed disk the same as a ruptured disk? I eventually needed to have surgery to have the fragments removed from the spinal cord. It was a very a painful existence until after my surgery. What is her prognosis? If you have to wait and see - try physical therapy before surgery. What does your veterinarian suggest?
I would suggest the same treatment for human bones and skeletal structure for your dog with physical therapy. Before my surgery, physical therapy was in order first. Impliment the same techniques: Heating pad for 10 minutes followed up with an ice treatment - I used a designated bag of frozen green beans (molds to body), for 10-15 minutes (re-freeze frozen bag). You could do this before bed on a regular basis for a few weeks. You might find an improvement. Gentle massages during or after treatment would be wonderful for you little one. It is important that your patient relax after each treament - so before bed is a good time. Actually, even before a nap too - (don't know your schedule). Sounds like alot of pampering for a dog, but why not try it - costs nothing. Also, try-try-try not to let her over-do it during this healing process.
Good healthy vibes are sent your way.
