Help me guess the breed of my rescue puppy! 14 weeks old!

A few months ago we rescued Betsy, our now 14 week old mystery breed. We were originally told that she was a Malamute/Retriever mix. After seeing her grow and the colour of her fur etc, we’ve started to look into other breed of dogs. She’s a very light brown/reddy fur with a thick under-fur, she’s got a slight brown mask and a dark stripe down her back and tail. This made us wonder if she had part German Shepherd in her.

She’s very loving and energetic. LOVES to play in water and roll around in leaves at every possible chance she gets. She hates the warm weather and will seek out any kind of cold surface to lie down on.

Any ideas would be great!
