interesting read mate,
ive got a lakie X, when he was abit younger he was like this, he'd try and dominate dogs 2-3x bigger than him in the park, he ruled my birds russell, used to grab the russells face and bowl him over, the russell wont go anywhere near him when his tea's down because he knows lol! i have to close the door because my dog will scran down, and then go and take the russells food off him, he got into a scrap with a big bull type while i was out, came of worse, i thought he'd be a complete b*****d with other dogs but it seemed to have sorted him out, he will still try it on
