After a while you realize that the dogs learn to accept this as home and look forward to their daily contact with people when they can go for a walk or on quiet days even play ball. Software designers, teachers and doctors volunteer. Young people studying to be veterinarians, retired people, high school students and college students volunteer. Photographers, journalists and artists volunteer. People who don't have room in their apartment for a dog volunteer so that they can have the pleasure of walking and playing with dogs.
Volunteers tend to be tolerant people with a good sense of humor.
I know because on my first night I tested everyone's patience. While the young men on my shift rinsed each cage with a deft sweeping motion, I always managed to douse someone inadvertently with the high pressure water sprayers. Fortunately even the dogs were patient that night. None of them bolted out of the cage when I forgot to brace the gate with my knee. Rottweiler mix did not wander too far when I forgot to latch his cage.
