Development of play behavior between potential guide dogs for the blind and human raisers.

This study shows longitudinal development of human-dog interactions in a guide dog raising program. Social play interactions between potential guide dogs for the blind (puppies) and their adult female raisers (PWs) were videotaped at home during the period from two months to 11 or 12 months of the puppies' age. The puppies and PWs established close proximity relationships by two to three months of age. The older the puppies became, the shorter time the puppies and PWs spent in intensive fighting and chasing play. The older the puppies became, the longer the puppies and PWs spent in waiting, seeking and possessing together play which needed the puppies' self-control, concentration and ability to cooperate with the PWs. Whether or not these behavioral tendencies which the puppies showed were appropriate for guide dog candidates is also discussed.
