Cody who was 4.5 yo at Christmas time, neutered, has never humped anything in the 2 years we are together. So Santa gives him a BIG teddy bear cos Cody LOVES to FLING things in the air. Christmas day he grabs that teddy Bear and starts humping away

, I give him my ungodly sound for NOOOOOOO and he stops, looks at me then the bear and walks away. I think about what should I do, leave it out or take away, it's so cute and BIG I decide to leave it out and play it by ear. It sits alongside his toy box, every time he went near it he refused to even look at it, then one day he grabs it trying to kill it but Teddy ends up under Cody's legs and the humping begins, again I give out the NOOOOO sound followed with NO HUMPIMG. Well Teddy sat for months by the toy box, Monday he grabs it starts fighting with it, flinging it all over, I am telling him GOOD BOY kill Teddy, praising him like crazy for playing with it, he stops looks at me starts to hump looks at me just as I am about to give out my ungodly sound and he STOPS the humping and continues with the kill. He knows he's not supposed to hump it, he is learning playing is ok, humping is not even if Teddy ends up under his back legs in the right position lol.
