Wondering what the mix is

Awaiting test results but I am curious what others see in him...Scout is almost 7 months old, pretty clear he is a heeler mix (even loves to go for the heels when we are out in the yard lol), but I am trying to figure out what else he is. The rescue also had some of his his sisters which are more the single color tan/brown and don't have pointy ears. They look like they have beagle, hound, or some sort of terrier. I assume he has some pit in him.
