This isn't going to be a helpful post but this thread reminds me of a funny story......
I was watching my nine year old nephew one day and he was watching Ava and Scoob play together. I had my back to them but was listening to Ty narrate what the dogs were doing. Then Ty starts laughing like crazy and started yelling 'they're partying!! they're partying!!'. I turn around to find Ava standing there with her ears pinned back and Scoob was humping her! Keep in mind, he's never humped another dog a day in his life and poor Ava didn't know what to think! He's never done it again though, much to Ava's relief.
