Our dog, a mini schnauzer, also loves the ground squirrels. However, he is either not fast enough or smart enough to catch one. He does love to dig and bark at where they have been. Plus he digs and barks at the exit holes for voles. Don't know what he would do if he actually caught anything. But mini schnauzer's were bred to be mousers and other small pests - he might not have been kept around very long!
