Whistles are excellent as they give a clear, concise instruction to the dog which it cannot misinterpret but before you try this exercise to the whistle you have to teach her what the stop whistle means by doing the exercise that Cazzie described above. If you just introduce it as she's coming towards you she won't have a clue what it means and you dilute its effect for future use
I wasn't just gonna toot it at her and expect her to know what it means
...shes many things, but shes not psychic
I will get myself a whistle, and do a search on here for whistle training, I'm sure someone else posted it on here a while ago, I'll start with the basics and see how we go
As for the treats, Betty is VERY food orientated, not too arsed about toys, unless she is in the mood to play
I have started to not give treats after every thing I've asked of her, as advised on here, she has to work harder for them now, getting a treat after doing a few tasks with loads of praise too, although I cant go too long in between treating, as she looses interest
