i haven't read the all of the post but just wanted to say that worked as a vet tech(for 15yrs) in california with one of the best surgeons ever.we did alot of myelograms/Laminectomies esp. on dachshunds.90% them did great with strict follow up care such as pain medicine(not too much) and crate living.just make sure you find a really good vet,preferably a surgeon,not a clinic vet-there is a BIG difference and most will let you make payments(just like the vet credit you applied for).i do understand cost and surgery will probably be the only thing that will fix her at this point.wishing you the best in whatever you decide to do.
