So, my pup is about 20 weeks old. She knows sit, come and is learning "heel". When I sit her down and tell her "come", she does. Now, when she gets something in her mouth and I tell her to "come", she runs around and won't come at all.
I've given her a tongue lashing from hell, but it doesn't matter.
Oh, and I've tried the "come girl, come girl" nice dog thing too. I actually tried the nice thing first, no luck. Any tricks out there??
