Growing up our male dogs were named after middle linebackers by my grandfather and I - Butkus, LT, Lloyd, Lambert, etc. - as they were Newfies. One of my greatest young successes (in my mind) came when we had a half Newfie, half something else: Polamalu. Wasn't technically a linebacker, but played like one.

Female dogs were named by my grandmother. it was usually some uncommon human name - Cora, Molly, etc.
