More: He came out of a rock quarry one night as I was finishing up at work, no collar, just a big friendly fellow who jumped in the passenger seat like he belonged there. Took him to the vet the next day to see where his chip was going to take him back to, but no chip. So he's with us now, part of the family, and usually the best part. Just a big sweetie and excellent guard dog, depending on what you ask him to do.
