Many years ago, before attending massage school, I got the information for T-Touch, a form of massage for dogs, cats, horses, and other animals developed by Linda Tellington-Jones.
The different strokes/techniques are given memorable names and are demonstrated on (DVD these days but I had the VHS tape)... so that pet owners can help their own animals to become calmer and happier family members.
She still offers instructional DVDs and information on her website:

In addition there are videos available to watch on YouTube:

Can't really say that it worked well for my little Ceely, she sort of reacted to it like it was a stimulant rather than something designed to calm and relax her.

But I have definitely heard of massage and exercise in warm water as being helpful to dachsies as well. I hope she finds something helpful, it's hard to watch a pet be in pain.
