About The Owner- (Donald F. Holmes Sr.) I’m a professional dog trainer and handler. I’ve been training dogs since 1986. I compete on a championship level in Schutzhund, a German sport meaning (protection dog) which includes three different categories; tracking, obedience, and protection / apprehension. At three different levels Schutzhund I, II, III. I’m a former Lieutenant Commander for the Canine Division for The Brunswick Police Department in Brunswick, Ga.
