I think Sit pretty might be Beg at least in my lexicon. that is the dog sits and then lifts their front paws off the floor The back muscles and hip joints take the most load in this position and not the knees. Jumping is another kettle of fish, as is weaving, like doing weave poles in agility.

As someone said you actually teach this trick on a solid non slip surface and first with their back cushioned either against a wall or your legs.

Building the upper thigh muscles and lower thigh muscles is a very good thing to do with a dog with LP. Once again I will mention swimming, as just a great overall exercise for dogs.

Then lots and lots of walking. Hill climbing, walking through sand and or different surfaces.

Believe it or not, but having your dog just stand still in a Stack position does strengthen all their postural muscles. And is a good exercise to do.
