Story
Koda is a very sweet and playful Mastiff looking for her forever home. She does well on a leash and listens well even if she's not sure of the command. She did come from a home where she was an outdoor-only dog, so she will need some extra training to be housebroken. She's never been with other dogs before but she pays no mind to her neighbors in her kennel. Koda is an absolute no for cats please. She is good with kids and very gentle. ##2178866##
