That's great! Any position they will freeze in works. But IMHO the remote "STOP" is more important than the remote "COME". You can always go get them, but you can't catch them if they go!

Since she's training for UKC Hunting Retriever hunt tests, the long whistle (sit command) is for "turn, face me, and sit; await further instructions."

She's not handling to a blind yet, but she is sending to the pile and learning the "go back" and "sit" commands. "Left" and "right" are next.

It's all so complicated. I don't think I could stand field trialing; I understand that's even worse.
