I hope you will give us an update as to what the vet that is treating your dog advises.
Usually they start with the least invasive tests as indicated, until they find answers.

On more than one occasion a physical exam, lab work and a quick ultrasound has led to a diagnosis for my dogs. It all depends on what the vet is looking for………..
And, at 13 it may be age related, but at least the vet should be able to come up with some comfort measures.
