There is a DNA kit you can get. I understand it is quit simple to use.
This boy is from a hording situation. The rescue I help has been working hard with him to get him used to people, he has a lot of traits of a coydog and some of the dogs he was rescued with do the coyote chatter. The rescue sent out the DNA test sample.
Turns out he is Cardigan Welsh Corgi mixed with Chinook, German Shepherd, and Australian Cattle Dog. I would never would have pegged that mix in a million years.
They also have 3 little female puppies who we were told were German Shepherd mixes...
This little girl
Not a hint of Shepherd in her.

Mostly Boston Terrier/Boxer mix..
My guess for your little girl would be Shepherd/Huskie or Malamute mix but so far I'm totally striking out on the guesses. LOL
