Ca-Ji's Xaro, known by his friends as Trooper (out of V Xaver vom Gleenbachtal SchH3 FH KKL1A and Ca-Ji's Heidi v Stachelhaus), was a shining example of the working German Shepherd. Trooper was an explosives detection dog, often referred to as a bomb dog. His partner, Joe Gallagher, is a former law enforcement officer who has two Federal Security clearances, FBI and Department of Defense. Together, they entered potentially life-threatening situations and Trooper was relied upon to keep both himself and Joel safe.

Out of multiple litters, a breeder may find only one dog that has the temperament and drive needed. Often, a dog will appear to have the qualifications, but after repeated exercises over time, a prospective dog shows that it is better suited for a family companion or household guardian. The training process is long, rigorous, and demanding for both the dog and the handler. From the time the dog is selected to graduation is about 12 weeks.

Trooper was selected at seven weeks of age after carefully testing an entire litter for drive, disposition, and working ability. His accuracy rate was rated at 96-98% (national accuracy rate for bomb dogs is 80%). Trooper could also locate guns, gunpowder, and gunpowder residue.

Explosive detection dogs are a special category of detection canines. The presence of bomb dogs is a force multiplier to any security operation. One dog team can do the work of dozens of law enforcement and security officers. Joel, Ca-Ji Shepherds is so proud of you and Trooper and your success-filled performance in the field. Please accept our sympathy for your great loss.
