there is a book called "how to teach your dog to talk" lol first you just reward differnt sounds other then barking. echo may be a better choice though, the book says that dogs with a shorter muzzle have an easier time taking then a dog with a long muzzle, because they can make more shapes with their mouths. I never tought perky how though lol it never even occured to be to try and teach perky to talk lol I just out of the blue here this "hhhiii" out of perky lol
