When I was growning up we had a male Boxer named Gizmo, he lived to be about 14. He was the best dog ever in my opion. So when I got married I kept trying to talk my husband into a Boxer, (he had never been around Boxer's before) but I knew I wanted a male, and another name that began with a G, but not Gizmo. So I picked Gunny, because my dad was in the Marines for 27 yrs. So I decided that would be his name, even before I got another Boxer, well my dad loved it!!! and my husband is such a Boxer freak now he says he'll never own any other kind of dog again. We do have a mixed female from the pound, got her as a pup, Quint, after Quint on the movie Jaws. It fits her too, she's 7 now. Erin & Gunny
