MINNEAPOLIS (WCCO) — A local rescue dog is now walking on three legs after an animal organization says he spent years with a painful injury from a shooting.

Sunny is a 7-year-old Chow Chow-Golden Retriever mix with Pet Haven in Minneapolis. His foster mother says he was injured in a shooting several years ago and recently received surgery to amputate one of his front legs.

In a press release, Pet Haven says Sunny’s life has never been easy. When the rescue group first took him in, he tested positive for heartworms and had to have all of his teeth pulled from constantly chewing rocks due to hunger.
