Sounds like Daisy could become a fear biter. That doesn't mean she
would make an unprovoked attack on adult or child. My Smokey is a fearful
dog & hates for someone he doesn't know to come too near to him. He likes
to make the first move with strangers large or small. I've had him since he
was 8 wks old & think he was born that way. (bad genes)

Daisy should not be put in the situation where she has to flee from
curious toddlers.
