My little guy is so persistent at getting anything and everything he can off the floor. I try to be very careful and keep the floor swept at all times. I also keep him on the leash with me in the house, but he always seems to find something. I've noticed his poo getting soft, so I'm wondering if it is from crumbs he is finding. I'm always digging things out of his mouth when we go outside also. He is 11 weeks old. Is this normal at his age, and do they outgrow it?
