Even though the toy isn't alive humping is a way of dogs to show dominance over something. He is actually being bossy to the toy, it's not actually a sex thing.
How I would personally stop this behaviour would be to put the toy on the floor and not allow him near it. I would block him with my body and a snap of the finger to get away from it. You may not believe this but this is an easy two day fix at most. |
