wow.. mine stopped humping after he was neutered He tried it a couple of times with his toy but I just said "NO" & took the toy away. he never does it anymore. my vet said if you let them do this it just becomes a habit & to stop him if I see him humping. he's 10 months now, neutered at 61/2 to 7 months & hasn't done this in months.
