"For many of the inmates, it's the first time they've actually been responsible for the care of another living thing," Lamb said. "It's extremely moving to hear the times these animals have changed them . or made them think differently about the decisions they've made. And it has a calming effect on the institution to have these animals here."

Butterfield was one of 10 inmates selected out of 100 who applied to Camp Canine when the program started. He fit the qualifications: clear conduct record and no sex offenses, child abuse or cruelty to animals. He had his GED.

Inmates like the program because it pays $2 a day - more than most other inmate jobs - and they get a private cell.

"You feel more free," said Butterfield, who had owned dogs before going to prison. "It really sped (time) up."

A very sweet story.
