Have a very worrying situation which I hope you can help me with. My Labrador playbites not only me and my husband but the kids as well. Kids dont like it and push him away which makes him jump up and do it more to them. Have tried to limit the interaction between them. Also when kids are playing in the garden our dog will come up from behind them and jump up and push them down. Have taken him to dog classes but nothing seems to work. Also he jumps up on people when we are walking him anyway. If he sees another dog though he will bark aggressively.
