Lucy seems to be nervous around new people,especially around children.The kids will try to pet her but she'll hide behind me or in between my legs Or sometimes she'll go hide by Kodie
I try to encourage her(i dont force her) to atleast go up to them.She hasnt shown any aggression toward strangers,no snapping, nothing like that.I've never had a dog thats nervous around strangers,so i dont have very much experience with this.

What should i do?
