That old saying that you can't teach old dogs new tricks isn't exactly true. Some of the best dogs that I have taken in over the years have been older dogs that were never properly trained. After working with these dogs for a few weeks, they began to pick up the basic commands that every good dog should know. If a dog doesn't learn, there could be a health problem preventing the dog from picking up what you are trying to teach him. This blog will break down some of those issues and help you get past the difficulties you are experiencing.
