Leo is a six-year-old boy who suffers brain aneurysms. He's undergone three surgeries since he was five. At age three, Leo was hospitalized and recovered more quickly when service dogs were brought to visit. His mother Yasmine noticed this.  

"As soon as the dogs came, he lit up," Yasmine, his mother said. "He started walking, he started having them do tricks...he was laughing, he was smiling, and within three days he was out of the hospital."

She decided to get Leo a dog and found Henry at a high-kill shelter. He was trained to detect Leo's seizures and since then he's a vital part of Leo's family.
