The best thing to do is redirect him.
Time for a yucky anecdote. My chihuahua is a neutered male and came to me with a nasty habit of sucking himself off. ALL of himself. He used to do it all the time. I taught him that he is not allowed to do it on the bed, the couch, or in front of guests. He will go to his dog bed and do it. That's been the best solution.
You can't expect him to never hump. But you can teach him when and where he can. |
