Fawn or brindle?

[roxy_girl_WA]

Our little girl is 11 weeks old and up until now a beatiful fawn color with a really nice blaze. All the sudden though these black hairs that almost look like smudges are showing up on her chest between the white and red and on the back of her legs, they're still pretty lite butr I thought that fawns werent supposed to have black anywhere except their face. Is she changing into a brindle?

Fawns can have black hairs mingled in or smudging, but that's different than the brindle stripes. Since brindling tends to become more sparse as the dog ages (the stripes "spread out"), it's not likely that she was a hidden brindle once she was dry.
