Basic obedience is the key to successful training.
You will have so much more fun with your dog if you practice the basic 4.
It is like building a house if the foundation is not strong enough; the House will collapse. If the House is not strong enough, then you won´t be able to place the roof on the top.
You see, it all starts with the foundation. Once the foundation is ready, you are prepared to move on with your dog. Don´t skip any steps that will lead to misunderstanding and frustration.
