I think it depends on the dog, not the breed. I have one chi that does his toy and one that has never humped. My gf has a female maltese that humps anything that can't get away from her..lol..so it is just not the males.

We had him neutered as part of the adoption contract, but ... he continued to hump (and I mean all the way to a little doggie howling climax) for about 6 years. Thankfully the frequency has finally diminished to near zero. It started out several times per day and always when company was here .... the sound of happy conversation served as some kind of an aphrodesiac for him. What an embarassment! I would have to tell him to "get a room" and remove him to an empty part of the house. :) Man he was a sex fiend. I've heard that chihuahuas are "worse" this way than some other breeds. Can anyone confirm?
