Welcome to Just Answer. My name is Jane. I have been involved professionally with dogs in the healthcare and behavioral fields for over 20 years. I’ve worked as a Vet Assistant and Behaviorist and have extensive experience in dog reproduction, as a breeder, for even longer than that.. Canine behavioral issues and training are also my specialties. It will be my pleasure to work with you today.
Unfortunately, x-rays are not the best diagnostic tool for a dog showing a hunched back appearance. A hunched back appearance often indicates upper abdominal pain or back issues. The testing would have ruled out many causes of upper abdominal pain however, x-rays might not rule out disc issues. Additional images such as a myelogram, CT scan or MRI would be needed to do that.
With a back issue, it is usually treated with anti-inflammatory medications often with pain relieving properties as well. However, to really get the best benefit, the dog should be kept inactive for at least a week meaning strict crate rest and only short leashed walks for elimination purposes. The dog should only be picked up properly with one hand on the chest and scooping the rear legs so no undue weight is put on the discs of the back. Many dogs with back issues avoid jumping and stairs if they can.
If Bella was given anti-inflammatory medications and is still on them, you might go ahead and try the strict inactivity for a week and see if there is improvement. If so, a longer period of inactivity may allow the disc time enough to heal and no longer be an issue. Disc issues are a problem in longer backed breeds like dachshunds and chihuahua.
Buffered aspirin can be given to a dog with a dosage of up to 5-10 mg per pound every 12 hours for pain. Keep in mind that a dog's body does not metabolize aspirin in the same way as a human and thus should not be given more than a day or two without contacting your Vet. The aspirin may need to clear your dog’s system before other medications can be given, so keep that in mind if you decide to give aspirin and be sure and tell your vet when your dog is seen. If your dog was on another anti-inflammatory medication, it would likely need to clear the system as well before aspirin could be used so consult your vet if that was the case.

I do want to mention that usually pressing along the back doesn't trigger a response from a dog with a disc issue. Often it is one specific type of movement that triggers discomfort and since a dog isn't totally sure what movement does it, they adopt the hunched walk to avoid it. Now upper abdominal pain can also cause a hunched appearance but those illnesses like pancreatitis can be diagnosed with bloodwork and examination. Also with many abdominal issues a dog will not have a normal appetite and will have other symptoms such as vomiting and/or diarrhea.
I hope I've given you a different direction to explore and Bella's discomfort is eased. If so, I'd appreciate a 5 star rating. The rating should be based on my answer and not any site issue.
