Caitlin Hamilton, age 24, gives her dog Hanai, a 17 month-old Boxer, a big kiss on the sidewalk on University Avenue in Seattle, Wash. Hamilton has been living on the street for eight years. She found Hanai on Craig's List when she was in Montana. A seven month old puppy at the time, he had a dislocated shoulder, a fractured elbow, and atrophied leg on his left side which she later had amputated. Veterinary clinic, Companion Pet, performed the $1,200 surgery free of charge. Hanai is certified as an emotional support animal for Hamilton who was brutally assaulted four years ago.
