my neighbors golden always wants to go in my house.
but maybe thats because shes never home to take him for a walk and he lives outside.
I will sday this though, they aren't the most loyal/protective dogs around, they might even be too friendly if you know what i mean. when i had a golden mutt, he was very friendly and would want to play with everybody, so i could never let him off the leash, but my dogue de bordeaux knows who is his rightful owner, and stays close by even without a leash, and still is very friendly, but can sense danger.
Somebody stole my purse from behind, and the dogue jumps on him and grabbed a hold of his neck and wouldn't let go of him till the police came, my golden was just running around paying hehe. i still loved him just as much.
all you need to do is train it properly, it requires to be a bit more firm with this breed, but really it all depends on how you treat your dog, you still need to be firm.
