Guess the breed

I know, to easy right? Read on.
We did a Wisdom Panel on this dog at work. His name is Emmett and he is a real sweetie. He came from a cattledog rescue group but his mom knew he wasn't a purebred due to something involving his color change from puppy to adult. Can you guess what else was identified in his makeup?

I've thought about doing one on Jenny because it's possible she might be a mix somewhere down the line. She sorta looks like a smooth brussels griffin cross to me at times. Not that it matters but it might explain her fabulous nose. Who knows, maybe she's a puggle! Ha ha! So who wants to guess what the Wisdom panel found out about this cutie pie?
