Kickass, the doorstop dog, says he will no longer “fetch” because he learned that it is part of instinctive behavior handed down from his wolf ancestors as they brought food back to the den and regurgitated it for the pups. The pups are long gone and they wouldn’t eat a GD tennis ball anyway. Kickass will, however, continue to chase cars, a DNA remnant of pursuing buffalo, until he catches one with an orange-haired driver. Then he doesn’t know what the hell he will do! There is that regurgitation thing, of course.
