Rhode Island State Police Ruby, an Australian shepherd/border collie mix, was the first shelter dog to train with the Rhode Island State Police. Her handler, Corporal Daniel O'Neil, practiced with the canine for a year, helping her become a certified trooper with the Rhode Island State Police K9 Unit by 2012. Before joining the state police force, Ruby was at Rhode Island Society for the Prevention of Cruelty to Animals (RISPCA), still searching for a home after months at the shelter and five failed adoptions. Even though the energetic pup had some hard-to-manage behaviors, shelter volunteer Patricia Inman stayed devoted to Ruby, training the dog and working to find her the ideal forever home.

I started to cry," O'Neil told PEOPLE in March about Iman's reactions to realizing that Ruby rescued her rescuer. "Even six years after not seeing her, Ruby was wagging her tail and jumping up on Pat, giving her kisses," he added.

"As dramatized in our Rescued By Ruby movie, they needed each other for that champion spirit to flourish.

" the statement concluded.
