Found rurally and never claimed, Doc is vetted now and in good health. Approx. 90 lbs, he is a people-friendly dog and will play with non-dominant dogs. Prey drive on cats, however. We're working on a bit of hand-grabby behavior, and he has a good understanding of basic commands and the leash. He's not a high energy dog ... likes his playtime and then a good long rest. We believe he's in the 2 - 3 year old range.
