I'm trying to train Romeo and Juliet to toss toys into the air, which I'd then like to generalize to tossing other things, as a cute trick. I tried it with a small soft toy (size of my palm). I've got no problem getting them to pick up the toy and also throwing it at me, but I can't seem to figure out how to get them to lift their head and throw it upwards. Does anyone have any idea? Is there anything I can do or use to try and increase the chances of them actually doing that behaviour? It's not really a behaviour that can be lured I'd think and they don't do it on their own ever with any toy so I can't capture the behaviour either. I know I'll have to shape it but if there's anything I can do to speed it up a little or just get that head up movement, that might help!
