In all honesty..... in a situation like that. Id set her up for a fall there, id go somewhere safe, where i could ensure nothign bad would happen to her, adn then when she plonked herself down and refused to move, id just drop the lead and walk off.
Failing that, if shed just pee off and have fun, then id tie her to something and walk off, preferably to behind a tree or just out of her sight so i could still see her.
Sounds drastic and obviously you couldnt do it on the road or anything like that, but i have removed MY support, attention etc from a situation before with good results.
It WAS a different situation, my dog was lunging and barking at other dogs and he felt i was backing him up. So i set up a situation where dogs would walk past, which he couldnt possibly reach (dogs and owners knew the deal), and the SECOND he barked and lunged - i left him.
He quickly figured out after only three or four goes, that barking and lunging got him NOwhere, other dogs were still present (walkign about not just standing staring at him) and his source of backup and support gone.
After that we could move on to me opening the treat bar whenever we saw another dog as he was more concerned then about where i was and NOT focussing on the other dogs as much.
If a dog laerns that when he/she throws themselves to the ground and refuses to move you are left with very few options, and all of them pretty much give the dog SOME reward for doing it. The only other thing you could do is stand there and ignore it. Picking up the dog, trying to cajole it with food adn toys etc would probably reinforce the behaviour.
Havent thougth my method through 100% ill admit, it is something of a gut reaction really (ie 'if you aint coming, sod ya, im off'), so if you think that MIGHT work, do think it through and discuss it with others first, and make 110% sure nothing can happen to your dog whilst you stomp off without her.
