There was a dog that stared Rosa. He had been declared criminal at age 16 because he started drugs at age 9. Rosa met a dog in the prison named Trep. There was a story behind him they adopted him and returned him 3 times.
Rosa started a program to help design inmates/ help prison dogs train. This program was a success. After this Rosa helped Trep find a home and he finally got out of jail.
After Rosa got out of jail he got intern\ job at the animal shelter. Rosa was proud because he couldn't believe how many animals he saved. So the program really paid off.
