I have two goldent retreivers.
1 is 12 years old - very well trained the old lady of the house the other is a little over 1 year old.
I trained her with the pincher just like my older golden was trained on professionally years ago.
My new golden I decided to train myself. So far she's picked...
She always had a plushy toy, usually in her mouth. If she got up, she carried it around. I suppose anyone who is on this site already is accustomed to that though. ;)
