Ok folks. I know there are some people out there who are well versed in training dogs. Well, I've got a problem. My wifes little schnauser (sp?) mix thinks that she is Houdini and likes to dig holes to get out of the back yard. She has also dug a nice hole kinda like a den right at the edge of the porch and at the foundation of the house. How can I stop this? It wouldn't be so bad if the dirt that she moved outta the hole was somewhere that I could find it, but, I just can't figure out where it's going. No way to refill the holes. She is constantly getting out of our back yard unless I keep her chained up which I hate doing. She got out a while back, got pregnant, now we have puppies to find homes for. She has gotten out once since the puppies were born 5 weeks ago. Please help!!!
