A. Humping behavior in dogs can be a non-sexual behaviorally related issue in addition to a sexual reproductive one. If your dog was neutered 6 months prior, it is likely that the hormones in his body have reduced already and are not the cause of his behavior. HOWEVER dogs that have previously been bred or had sexual activity prior to neutering may still exhibit interest in and sexual behavior toward in-heat females.
In most cases, the humping behavior is not sexually related and can actually be a sign of "dominance" in dogs. While this term is largely outdated in behavior, it is one that is done usually on one dog to another to show "hey I'm the boss, i wanna be in charge". Dogs can sometimes take turns doing various similar behaviors during play, or one dog may want to take charge and only allow him or herself to do it. (Yes females can do this too!). If your dog is humping a pillow or toys, he may just be trying to tell his toys he's the boss! If you feel uncomfortable with this behavior, then stopping him in the act and distracting him with a different game is best.
