I have a four year old daughter and a 6mth old baby. I have a shorthair and a lab in the house. Both are fine around kid's.
My four year old daughter recently bit (hard) my gsp in the head and she never bit her back. She can sit on her ect.
It's hard to say though because each dog is it's own. Even with mine, as much as I love and trust them, their still dog's.
