Darby. We probably have more dogs per capita than any neighborhood in our town. But most of them are either inside dogs or stay-in-the-yard dogs. Not so Darby. This little Shih Tzu has the run of the neighorhood. He has fathered several litter of pups, as his little manhood is very much intact. And although we often complain about him being a nuisance, we all love him.
