I am an experienced vet and happy to help.
Do you you know if the vet did a myelogram - where dye is injected into the spinal cord?
She did not
As you have mentioned my big concern is a spinal problem in this breed. When I hear "yelp again, loudly, when we tried to pick her up" this indicates to me a spinal problem
An xray does not always pick up a spinal problem and your really need a myelogram to detect compression of the spinal cord
Ok, so this would tell me if there is a disk problem?
Yes the myelogram definitely would or possibly a CT as well.
This can be quite urgent in these breeds as they can lose function of there back legs if this is not picked up early enough
Ok, so the spinal cord is likely the problem....so if there is a compression is surgery the treatment?
Depending on the severity surgery may be required to decompress the spinal cord. HERE is a linking discuss the disease and the different severity/grades of the problem.
Unfortunately the pain relief is likely to be just masking the problem at the moment
Some vets are unable to do a myelogram themselves so you may need to request referral to have this done
Ok, Thank-you, I'll look into this further.
