My FEMALE Phoebe will hump her doggie stairs. It's funny, because thats the only thing she humps. I thought at first that maybe there was a smell on the fabric cover (it was given to us), but then I bought a second set so she could get on the bed & she humps that as well! I've heard that humping is a "dominant" issue, and not always fixed by spaying/neutering. Good luck with your pup! |
