I don't really know where I got this idea but I have always thought that tradies take their dogs to work with them to act as a sort of guard dog for the tools in the back of their utes. Maybe that is where the idea of taking a dog with them started and it has evolved to the point that a lot of tradies do this? Or maybe I made that up in my head
How annoying for you and your poor pets though.
Many years ago when I was a kid my Mum sold something in the trading post and the guy that bought it brought his dog along when he came to pick it up. The item required some dissembling and whilst he was doing it his dog got into our guinea pig cage and killed one of our little guinea pigs

We were all so upset but the man was absolutely devastated and even cried. We ended up feeling bad for him!
