Poor kid. Don't ever let her tease a dog for human food. around 5 or 6, I did. Got part of my lip half the size of a postage stamp taken and needed stitches. Not fun. She sounds funny!
xd Definitely not. They haven't had much experience around dogs (Olivia was around my parents dogs as a baby but not since) but we'll stress to ask before you pet the dog, don't bother the dog when they're eating, don't tease the dog...things like that.
And as harsh as it sounds if they WERE messing with a dog (teasing, or whatever) and they were older and got bitten it would be their fault.
Right now even if I could get a dog I wouldn't because I think they are too young and they would just drive the poor animal insane. Haha
