German Shepherd / ??? Mix

This dog has been the most special boy to ever come into my life. He was a stray before the SPCA picked him up for likely over a year given how matted and compacted his coat was, but not he's thriving in his new home, despite still having a very reserved and polite (though not fearful or anxious) demeanor.

The Embark genotype test is pending. I'd love to know that y'all would bet the results might show! He's a bit of a mystery around the dog park. He's a barker there but not vocal at all at home. Otherwise he's very biddable and focused, loves to chew on toys (took him a few days to learn toy from non-toy) and as of yet, miraculously doesn't shed much at all.

Now taking guesses! I'll report the results when they come in!
