That's what we call Oban's big teddy bear.  I just couldn't bring my well brought up self to make the title, "humping question".  :)  Oban (6 months old) does the nasty with poor Poppa Bear.  I say, what the heck, he doesn't go after people's legs, or furniture, leave him to it.  In several humping question posts I've seen displacement on to another object suggested as a method of control and that's what it seems to me we've already got, why rock the boat?  But OH doesn't like it.  He thinks it is bad, embarassing and undesirable and we should stop it.  If people come over I hide Poppa Bear.  Think I should stop it altogether?  Suggestions as to how?

My first worker had a huge stuffed Tigger toy which was far bigger than him when I brought him home at 8 weeks. Not one to be daunted by size he started humping poor Tigger with gusto from about 4 months old. He never humped anything else and I just distracted him with a toy or a treat when he started at it and he grew out of it after a month or so as he started teething and was more interested in chewing so poor Tigger went from being his love interest to being disembowelled and ripped to shreds. If it's a problem for you or your OH I'd just remove the toy and if he tries to hump anything else just say 'ah ah' and distract him onto something else with lots of praise. My boy has never humped anything else since he grew out of his Tigger love phase though.

My friends JRT humps a cushion she has had since being a puppy (Now7 yrs old!)
She is allowed to do it unless they have people coming round and then the cushion gets hidden for the duration of the visit! She does not do it all the time and can forget about it for weeks at a time, maybe as Oban gets older he will hump Poppa brear less ? I would be tempted to let him have it and just quietly remove it if visitors arrive ;-);-)
