You never know.... If its definatley got whippet in its blood then its probably going to work in some sort of fashon, as kids (30 years ago!) we used to nick lurchers from the local dogs home an give them a run on some very good an famous coursing grounds near by, most gave a good account of themselves an were given good peminant homes, one was exceptional, killing the first four that we put her on, lived to a ripe old age too, seein plenty of work an bred some good pups.
Works sometimes with terriers too, a good mate has a excellent worker (above an below) from the local dogs home.
Defo not
