Abstract: The disclosure provides a dog collar and leash system. The system may comprise a collar structure. The collar structure may include an elongated flexible strap having a first end portion, a second end portion, and an elongated central portion extending from the first to the second end portion. A closing structure may establish engagement of the first and second end portions to define a closed loop. The system may include a leash structure comprising a housing and a reel supported in the housing. A cord may be spooled on the reel. A spring may be mounted in the housing to provide a biasing force on the reel. A handle portion may be disposed at a free end of the cord. The system may include a keeper structure comprising a first keeper element to retain the handle portion in fixed relationship with the collar structure when the cord is fully spooled.
