I have a basic understanding of Isometric exercise and would appreciate input as I want to be sure I’m on the right track and am unable to find out much for duration.

I always have Pisa in my loader with me, today while I ploughed some new paths it appears to be a great way to work her muscles while easing up on her hips.

The cab is pretty much window and big enough that she can walk around one side of me and behind, with a few spots to perch her front legs on, it leaves her hind feet on the cab floor.

depending on the spot, Her back is either level, about 15 degree, 30 degree and super close to 45 degree, she keeps her back straight in all positions.

she seems to vary her position often to look out a different direction, we get out for a short walk every 45 min or so and have not been longer than 1.5 hrs total.

I drive gentle, switching direction so Pisa is not rocked around, and stay in low range ,

I’m not sure how long its ok for? She loves it, enough room for a few sits and hand touches, mostly her looking out.

Thanks

no Steve, I care about my dogs.

Ok. Most of what I remember about managing dogs with bad hips or elbows had to do with weight management and excercise like swimming because its non-weight bearing. It sounds like you're doing just the opposite on the excercise by having her bear weight in a way that I think sounds like its extra stressful on joints.

thank you for answering my question and explaining where I was wrong in my assumption.

Yes, it would be all joint-force to maintain balance during inadvertent movement (as Steve points out)..
