Our Dino loves playing with his frisbee - I just started throwing it for him and he soon got the hang of it. He does have what we call his frisbee tantrum when he drops it and can't manage to pick it up again - he stands on top of it and digs like mad making frustrated yelping noises
So best one is his red kong frisbee which is made of soft bendy rubber - gentle on his mouth and he can dig at it with his paws to pick it up.
As you see frisbee is his favourite outside toy:
