We've had our Border Collie/Chow mix since May. He is now 20 months. He is the neediest dog I've ever seen. He needs attention almost constantly. That's usually not much of a problem since there are 5-7 of us here all the time. It seems if he thinks he's not getting enough attention, he will go in my younger girls room, pick up toys he can find, walk past you, LOOK at you, then walk to his kennel with the toys. If we don't catch him, he will chew them up. He's destroyed several Barbies. Any ideas how to stop this?
