OK, my little sweet girly girl Patty has a humping issue.... She's very social with people and dogs. Loves to play and interact with other dogs, but, once she starts playing with a dog, particularly a very small dog she ends up humping it! Male or female,doesn't matter. If the dog snarks at her she will stop, but a few dogs have, most just stood or sat there at allowed her to do it (which is when I pull her off). WTH? At home she has tried to hump Apollo (when he's laying down) and Molson. Apollo will stand up and walk away (she can't get him then) but Molson just sits or stands and lets her do it. If I just pull her off whatever dog shes doing it to when I put her down she's back to "normal" again, playing nicely. I didn't really think it was an issue, just natural dog behavior, until last night when she was humping a stuffed animal in her crate....*sigh*.......She isn't a "dominant" dog by any means, she's actually super submissive and can be very shy (at first).
