Our 4 month old puppies have found the joys of digging, and I'm curious on ways to stop it. I've seen the stuff in the stores that supposedly will stop it, but I don't want to plop down money and not have it work. One spot I've gotten them to stop at, but at the expense of them doing more digging at another. I know once the grass comes in, that will help stop it but I can't get the grass to grow until they stop growing.
