when Duchie had her troubles, Doc Chuck told me to put her in water just deep enough to come to her shoulders (which is not a lot!) and use my hand to swirl the water and keep her a little off balance. the water was warm which felt good to her and it was high enough that her buoyancy took the weight off her back and legs but she still felt compelled to try to balance.

dunno - of course I DO NOT have DVM after my name, but worth checking on.
