I think Harvey has learnt stop (sit) at the whistle. Went a bit to pot when we tried it in the garden, but he's grasped it indoors!!!!
The smile on my smilie is pretty similar to the one that I've got now- well proud of my little loon!
Plus, armed with mature cheddar he waited for my command before running to fetch his ball. Dead chuffed!! He's still a loon and jump and pulls on the lead, but at least we've cracked something!!!
