Many dogs can experience a sore back and your vet will usually evaluate for disc problems and most cases this is not the problem. If your vet finds no disc problems then u will get meds for pain and inflammation. This approach will not fix the problem but rather treat the symptoms and cause other new issues due to compensation.
Most commonly the issue is a subluxation of the spine which is literally a spinal joint that can get stuck in motion causing nerve pain and muscle strain. A Certified Animal Chiropractor can easily evaluate your dog for this and a chiropractic adjustment along with cold laser can correct this. Your vet is not experienced in diagnosis of this issue so it will not be detected, I teach at Options for Animals chiropractic college and can tell you that the Vets that I teach are always amazed when I teach them about spinal biomechanics since this is not taught in their school.
