Ollie did the same thing at that age! And it was normally my arm but we always told him no and grabbed a toy and tried to get him interested in the toy but he soon would be humping again! and we just repeated this over and over and he stopped doing it as much but now he is neutered and hasnt done that since. (he is 8 months old).
Oh but he will hump his 2 yorkie friends that sometimes come over to play but i have learned that is to try to show dominance. We of course tell him no and pull him away and throw a toy--etc... |
