if it was pink, would it still be dog hair??

This morning, I was fixing Paigey's hair while Macy was putting on her sandals.

Macy: There is some dog hair in my shoe.
(I glanced up and saw her holding some white string)
Me: Macy, that is white. (Bo is black)
Macy: No, from a dog of a different color.
Me: That's string, silly! Like string from your clothes!
Macy: Are you going to blog that?
