So our Max is almost 18 months old... he's a great dog... amazing with our 2 year old son, has never chewed anything in our house, an alert watchdog, great with our other dog, etc etc... But our one pet peeve with him is being in our faces or all over us. He will lay on the couch with us, which is fine... but if you are sitting there, and he comes over or you call him over to pet him, as soon as you start to pet him, he jumps up on the couch and literally puts his face right against yours sniffing... nothing aggressive at all and not even usually kisses... just like sniffing your breath or something... At the slightest affection or attention, and he has to be on top of you sniffing you, tail wagging. At that point we just push him down, say "down" and stop the affection... I was thinking that when he realizes that doing that ends the affection/play, he'd figure it out and stop doing it... but it's been months and there is no change... any ideas?
