ok so my girl is now 5 and she has always been a little bit timid. her normal behavior is to start 5 to 10 feet from someone and bark at them till she builds the courage to get close enough to sniff them and then she is good, this is what she does with adults. Kids on the other had she makes me very nervous. she is amazing with my son who is 7, there is not one little bit of me that thinks she'd hurt him, however his friends are another story, I do not trust her with his friends anymore :( she runs at then, and although she has not hurt one (yet) she looks like she nips at them and jumps at them. I'm not sure why she is doing this to them, and Im scared that she may bite one of them one day even though she has never been a biter. Has anyone else incountered this?
