Because of his condition, Harry has limited mobility and has to rely on a wheelchair do move around. He got an assistance dog, Addi, in 2017. Addi helps Harry by doing things like opening doors, opening drawers, turning light switches on and helping to remove socks and coats. “Most importantly he’s a constant friend and he encourages him to go outside, which, prior to having Addi, he never liked doing”, Harry’s mother, Hilary, noted.
