Well, I misspelled schutzhund...oops, damn german words(confusing).

Schutzhund consists of three phases: tracking, obedience, and protection. A dog must pass all three phases in one trial to be awarded a schutzhund title. It is primarily a competition with german sheppards and belgin malinosis, but is open to all breeds.

KNPV, is an abbreviation for "Koninklijke Nederlandse Politiehond Vereniging" or Royal Dutch Police Dog Association. This organization conducts police dog trials and offers certificates that are among the most coveted and respected in the world.

French ring is another dog sport, but unlike the other two mentioned above, it consists of only obedience, and protection, but is known to have the toughest agatators, or helpers of any ring sport.

There are many other ring sports for dogs, but tese are some of the more poplular ones.
