Two labs grace our house. The oldest is now almost six. He grew up and became a good dog seemingly on the day he turned three. Up to that point he thought 'Gawd' was his middle name. The younger lab, a girl, is almost three. Hope she goes through the same transformation as the older one did. Of all the labs I've owned, most seem to calm noticeably about age three with only occasional fits of insanity afterwards. Labs simply wouldn't exist if they weren't such lovable beasts. Every time they eat something I just remind myself it'll be funny some day.
