Identify Puppy/ Breed Guesses ?

I'm the proud/happy owner of a 2 year old pit/lab mix that I adopted when she was 9 weeks old. - Pepper has completed obedience classes and 5 agility classes.

Pepper needed a playmate and I was ready to go a few more rounds with puppyhood. Reno Humane Society introduced us to 3 month old Shadow and I knew she was the one for our family. I was told she was a pit mix; but she's got such big ears and such a narrow head/nose I'm not really sure what she is - other than stinking cute!

Any input is appreciated.
