APPDA
APPDA is a single-program sport. The American Protection & Patrol Dog Association writes the rulebook, certifies decoys and judges, sanctions trials, and maintains titles. Handlers do not cross-register APPDA titles with PSA, Mondioring, or IGP — those are separate sports under separate bodies. The cultural identity is 'real world' flavor: the exercises are set by the rulebook, but the judge varies their order, distractions, and props trial to trial. Open to all breeds and mixes that meet temperament and control requirements; no breed-restricted divisions appear in current public materials. Dogs are registered directly with APPDA — membership is $40 and includes one scorebook — rather than through AKC or FCI programs. APPDA certifies its own decoys and judges, and decoy quality is a defining feature of the sport's culture.
