Hey, our 18 week old mini dachshund Archie is being a little rat when it comes to his pee pads! Until about 2 or 3 weeks ago he used them fine, virtually trained himself to use them. Now when we are at work, or he is left unsupervised, he is dragging them around his area of the house and spreading poo and wee everywhere. He has loads of toys and things to do, we have no idea why he has started this. Any one experienced this before?
