Hey.
I've got a beautiful 6 month old lab boy. I adopted him at 6 months and it was pretty obvious he'd had little socialisation and training. I've been doing a lot of work with him and he now knows 'sit', 'come', 'stay' and 'shake'. We are working in 'place' (as in 'go to your').
One of the things I've been working on is to sit and wait for his food and to sit before the door opens or crate door opens. He's great at sitting before his meal and waiting for the 'okay'. At the door? Not so much. If he busting for a pee, he sits like lightening, but at any other time - he can stand there for up to 3 minutes before he complies. I don't endlessly repeat the command, and I DO reward with a 'good boy' and an open door.
Is he just being stubborn or is there something I'm missing?
