We got a lovely lovely 15 mo staff x jack russel x who knows the other day who is used to our age DCs. DH though (used to german shepherds etc.) has started to play fight with her - I have told him not too because it's not fair as she won't understand 'trying to get the ball' etc. is a game just for playing with adults, or is it OK to 'play' with dogs? I have always had dogs, but I was older than my DCs. DH has always had dogs but would be very playful with them - hiding and calling them so they find him and pretty much pounce on him when they find him etc., rolling around the garden that sort of thing. Any opinions?
