He seems to see our kids as play mates as well. My oldest DD will creep up to him saying "nice doggie" and this gets him going. He jumps up and runs and chases her and she runs away. He will hide and stalk her waiting for her to pass by and Then off they go again. Its great fun and they could do this for hours.
My concern is that they really get going. He will try to wrestle with her the way he does with other dogs. He uses his mouth on her biting, growling, chasing etc..... It's Never done aggressively. Never. Its always in the same style of play he does with our dog where they run and chase and wrestle in the backyard and, the second she wants to stop, she just picks him up and he immediately stops and starts giving kisses (licks) and calms down.
He's only 6 lbs so, he can't really hurt her but, sometimes he will go too far. One time while she was hiding under a blanket and he was trying to get to her, he accidentally bit her cheek. He didn't break the skin but, it did hurt.
I sometimes wonder if it's a good idea to allow him to see her as a play mate. He adores her and will instigate the play as much as she does but, I worry about allowing him to chase and growl and use his mouth in play with her. Thoughts?
