, aka Bogie the Rogue Yogi Doggie, the Hound of Renown, regally allowing himself to be sniffed by a far lesser Dane.
He was given to me, and, really, the best dog you can get is the mutt whose heart wrenches you the most at your local SPCA. Mutts tend to be the healthiest, get all the good dominant genes from all their forebears, and a shelter dog will be grateful unto death that you rescued them.
