A Teckel will do just that, small bit of digging work and ratting,,, tracking up. Bushing. Universal really. They have the heart of a lion... I say to mine if you could look in a mirror and realise what you are you'd have a culture shock. I've got a litter of 5 2 week old and i've knocked so many people back that didn't have a clue. Can't just throw a dog down a hole and expect it to have a do' and be bomb proof. One guy expecting it to be down the hole after its first jabs. Told him where to go as you can imagine.
