Thanks for the great replies; I think he's probably part Akita too. Good call.
We've had him over a week now and love him to death. We were training him to 'Stay' in the back yard yesterday with the gate open while we moved tree limbs out to the truck and he did pretty good. The couple times he did come out through the gate; he didn't run off.
He's not too tall; I measured him last night at 20 inches to the back 26 inches to the top of the head.
