So sorry about your girl, Sarah, and wishing Rhona the very best of luck, the therapy sounds great.
Just a thought......and no disrespect to your vet's diagnosis; :-) DM is hard to diagnose and is mainly a rule in after everything else has been ruled out.
It's not painful and most dogs are blissfully unaware that hind leg function is not as it should be and are usually happy and content in themselves. I'm just wondering for there to be such a dramatic improvement in your dog after her session, if she was in pain in any way?
Just to make you aware, (you may be already), there are other problems that can mimic the signs of DM, i.e. Disk Protrusion, Spinal Neoplasia, Myelitis, Diskospondylitis, Lumbosacral Stenosis (Cauda Equina Syndrome), to name a few. All of which can result in muscle atrophy in the back end and neurological deficits in the hind legs.
I had a GSD diagnosed with DM 18 months ago from 2 different vets. It wasn't DM at all; he had a protruding disc that was putting pressure on the spinal cord. Needless to say, the outcome was very different to what it would have been if we settled for the diagnosis of DM. He's still going strong and made a good recovery.
Anyhow, best of luck and (((big hugs to you and Rhona))).
