Earlier Kiara was out playing with an old male Pittbull, and all of a sudden she decided to take over the male role on top... I was shocked!

Could this mean that she is starting her first heat, or is she just weird? She isn't fixed yet, the appointment is in a few weeks.

Girls mount all the time.

I have all girl dogs, and the humping started with 10wk old Mixie mounting a 6mo old Soshanna. Now, they take turns mounting each other. The truth is dogs mount over dominance, anxiety, excitement, play, etc. Its a social behavior, but it is an indicator that things might need to be slowed down a little, to avoid an issue.

My female is my humper also we just tell her "no" or "leave it" she definetly does it more then my male and doesnt listen as well as the male when told not to do it. Though i have to admit it is hysterical to see her hump my mothers male rottie mix from the back as my male humps his head. We do chase them off but its always as we're laughing. They actually have a bigger problem doing that to the rott then they do with my sisters pitty mix. None of them are fixed yet.

Come to think of it my last female was always humping too not as much after she was spayed but shedid still do it sometimes. My aunts girl humped before she was spayed then never did it again after spaying.

Oh okay that's good to know. And that makes sense Eric, I could tell that she wasn't wanting to play as rough as the pitt was.

And yes Bella, it was hilarious! The few of us watching were all so shocked that it was about 5 seconds until we really reacted hahaha
