Today while walking my dog , he met a feisty female shihtzu. They checked each other out and then she started to hump him like he was a female and she was a male. Her owner said "she is trying to teach him what to do".I'm not to sure about that, but my dog didn't like it and nipped at her and he looked at me with his eyes and told me he was finished with his walk and it was time to go.
I think she was just being dominate but maybe she was trying to teach him something.I thought it was funny because it was so unexpected and strange.
