Well, I don't have a chi but my tzu likes to dig occasionally. I keep my yard and my flowerbeds up. It's one of my hobbies so her digging is unacceptable. As soon as I catch her. she looks at me then runs straight for her kennel b/c she has to go there for a few minutes. She is doing it less and less now. Hopefully she'll stop it for good soon! :lol:
