we bought a stuffed animal so that my dog could play with it. all was fine until he hit doggie puberty. All of a sudden i walk into the living room and my dog is in full three point stance pounding the stuffed animal. He was going at it like a lil possesed beasty. funny as hell. As he got older he still wanted to bone it, but got so big that when he tried he'd topple over. Even after falling to his side he'd still thrust away. lol
