Ok, for me the answer is obvious, I was just wondering if it's a lack of training or it can just be the dog's personality. Boris seems extremely stubborn to me. He knows the 'come' command perfectly, and I'm still reinforcing it with treats, but... When we call him to the room with the gate, very often he will stop at the door, and refuse to go in, in case we close the gate behind him. So he just stands there looking at the treat while a big puddle of drool forms up at his feet. Same thing for outside, when I call him he will go to the door and look at the treat half the time, because he doesn't want to go in. I really don't think it's lack of training, as he comes to the door everytime... and I just can't reward him more for coming, because when he does he gets his favorite treats. Just now he got even more sneaky, came in, grabbed the treat and ran back outside with the treat still in his mouth If anyone knows how to fix that behavior, I'm really interested, but it seems to me it's just his nature and it will never change. The only thing I can think of is no longer closing the back door when I call him, but I don't always do it, and I close the gate in the room after him maybe three times a week now, and he still won't get in 95% of the time when I call him. Tips is easier at least, he always comes whenever and wherever I call him, lol.
