I have a 4 year old pekingese with a disc problem that has been diagnosied by a vet. He can walk some on his back legs but he is wobbly. They told me that he needs to have surgery and it costs $3000. I am a single women who lives by myself. There is no way I could afford that. Someone told me about wheelchairs they make for dogs. I am waiting on companies to send me information. I just hope I am doing the right thing.
We once had a Doxie with back trouble (wasn't a disc though, it was nerve damage). After a shot of Vitamin B 12 and a regimen of Prednisone, along with some extensive in-home therapy ["swimming" and rub downs daily]. She got better. As a matter-of-fact was back to 100% in about 6 weeks. I am sorry for your baby. We also looked into the wheelchair possibility (when we were still unsure of her recovery). Our Vet knew a man that also had a similar injury in his Doxie-- which never got better-- but he built it a little wheeled cart. We knew that was an option.
What have the Vets said about the wheelchairs? Did they say it was a possibility? If you haven't asked them please do. Just like the OP said...it could be an injury that a wheelie cart would only further the damage.
I would suggest talking to the vet about the possibility of a wheelchair for this particular injury...A lot of disk problems can heal themselves, it can take months, which is why surgery is sometimes recommended, but that doesn't mean that it's the only option.
Herniated disks, for example, are often managed with pain medication with human and animal patients alike, while waiting for the injury to heal. Surgery can be dangerous and very expensive, so I understand that you're looking for other options (other than putting your pet to sleep, which I'm sure you're trying to avoid).
If the injury doesn't hurt, but is causing paralysis or weak limbs, then a wheelchair can be VERY helpful. It allows them to regain mobility while they heal, and even better, it can speed up the rehabilitation process! Wheelchairs can actually get your pet back on his feet SOONER.
I hope that helps...and if you ARE forced into surgery because of pain, then I would suggest finding a vet that is willing to work out a payment plan with you, if your current vet won't. Some vets are particularly understanding about money issues, and to help your animal, will allow you to pay off the $3000 a little every month.
