Short story: Musashi was my husband, Ty Whitehair's dog. Ty and Musashi achieved an AKC CDX and a SCH3 title, the highest level of Schutzhund dog training. Schutzhund (German for "protection dog") is a rigorous sport that tests a dog's abilities in three main areas: Tracking, Obedience, and Protection. A SCH 3 title means a dog has passed the most advanced test, showing high intelligence, obedience, courage, and control. Musashi also lived a long and happy life to just over age 17; he was the first Bull terrier that I ever slept with :)
