While I owned a few dogs throughout my life, I've never had a shop dog. The first place I worked though, had Betsy..... Betsy the Beagle. She just waddled around and constantly was sleeping at my feet, although it wasn't my dog. When someone would come in the shop, she'd get up, wander over towards the door, start shaking and then pee on the floor. Always. She was still a little stinker. Actually, for a beagle, she was big and fat. The owner was always feeding her people food. Believe it or not, when Betsy died, his next dog was another beagle and guess what he named her. Yep, Betsy. That was really weird.
Gonna look for my paint kit. I have a few of them. See if I can post it up, before I go home today.
