The late James Herriot has this story about one of the places he would visit....the farmer had a dog that would chase cars down the driveway...as if to run them off...One day Herriot's son was with him and the dog was chasing their car...the son squirted the dog in the face with water....the dog stood back bewildered...but next time they came he was chasing cars again...so they squirted him again...until he finally stopped altogether....

Later when that dog had puppies the farmer called Mr. Herriot up asking if he and his son would like to train this batch, too....
