Researchers tested whether one week in a foster home helps dogs from animal shelters. They watched dogs before, during and after the week at home.

The team measured cortisol, a stress hormone, from urine and used activity monitors to see rest and movement. During the home week, cortisol fell and dogs rested more. When dogs returned to the shelter, their cortisol did not go higher than before. The study suggests that one-week foster stays can calm many shelter dogs.
