As Maestro has canine arthritis and Inter-vertebral Disc Disease, passive stretching is necessary so as to not aggravate his achy joints. The main thing about any passive range of motion technique is to support the joint as you are stretching a muscle group.
After attending the Heritage Day festivities offered by the City of Calgary this past summer, I caved and ordered Maestro a dog stroller from Amazon. You try carrying an arthritic dog who can only walk a few feet before wanting a break. And when he wants a break, he’ll just park it wherever he stops. He doesn't care if he’s in the way.
Maestro’s condition has certainly stabilized with the combination of acupuncture, water and laser therapy.
