Update 6/3, 6:30 p.m.: Barkley is still available for adoption, as no one has stepped forward to take him. He successfully had his dental work done, but his teeth were in rough shape, so many of them were pulled; he has two left. Shelter volunteers say he needs someone who can give him special attention.
Barkley has not had a lucky life, but he's looking for someone who can change that.
He was found in a trailer park, where he'd likely been abandoned - perhaps because he had medical issues that his family didn't want to deal with.
He's now been at the Daviess County Animal Shelter in Owensboro, Kentucky, for more than a week, and no one has shown any interest in him. So far, he's been so scared that he just sits in his enclosure and stares at the wall.
