No-one is about to claim that training a dog is an easy thing to do. Dogs are animals with personalities, and whether or not those personalities are amenable to training, they will present different challenges with each different dog. It cannot be denied that some are easier to train than others, but no dog is untrainable. It is simply the case that some dogs need to be given more of a chance than others to pick up what their master wants them to learn. After all, humans are the same – if you got straight As in your freshman year of high school, congratulations, but you are in a minority.
So it makes sense that there is help that can be found to improve the behavior of a dog you are finding hard to train. As ordinary “civilians” when it comes to the overall behavioral patterns of a pet dog, it goes without saying that we will not magically have access to the “button” inside a dog’s mind that makes it behave well, perform tricks or anything else you want it to do. There are professionals who have written books and made DVDs showing helpful tips and hints, and a wealth of websites which do the same.
You may even take your dog to a trainer who will be able to identify ways to get it behaving the way you would like. The expense of doing this makes it something that you may not want to do too regularly, but if all else fails it can be beneficial to you and to your dog.
