having the rug eaten out from under you

Our doggie Farmer was once always deservedly in the dog house. He used to eat everything including all of our rugs leaving our floors bare. The chewing phase seems to be done so I'm making some new rugs. One is braided and the other crocheted. The braided one I've taken apart several times to get it right. The crocheted one is made out of old clothes and is sooooo easy except that Farmer plops down on it every time I start crocheting.
