We’ve all heard of hero dogs — dogs who work as therapy dogs or service dogs and especially dogs who assist police and fire departments in solving crimes. Some of you may have treated these dogs. One such dog, Kai, is an arson dog. Back in 2011 she discovered the fire accelerant that burned down an Alamo Height’s house, a woman, her child and her roommate. Kai has been a successful arson dog for five years. Part of her success is due to the help of her veterinarian, Lewis Radicke, DVM. Dr. Radicke works at the Lincoln Heights Animal Hospital in San Antonio and sponsors Kai’s care, an action he was recently honored for. "The whole staff loves her and they love to see her. And you can see how she reacts," Radicke told KSAT 12. He added that he’s proud every time he learns of a big case she’s working on because his care is partly responsible for how well she performs on the job. "There are a lot of these cases where she's spot-on. I mean, she picks up on it and she knows," he said. Radicke was not the only honoree. The American Humane Association honored Kai with the Hero Dog title in 2014.
