Ruby is my Airedale. Ruby is offspring from Don Turnispeed's German Airedale and one of his hunting bitches.
Turnispeed's German is fairly big for Airedales (iirc). He remarked to me once that he was somewhat disappointed with the German's hunting abilities as he tended to want to stay closer to Mr. Turnispeed versus running with the pack.
That is just what I wanted in a protection dog, so I went with a half German bitch.
