There's a lot of reason why people likes to own a dog. They can be a partner, mostly for older people or in cases where police are using dog's skill to help their job (for examples in the borders), they can act like a guard when you are sleeping at night, and in most cases, they are fun to play with.
Nevertheless, dogs must have proper training in order to be able to do so, thus when you buy new dogs or when you have a puppy dogs, you should train them so that they can do exactly what you wanted them to act.
Puppy training provides you with a good articles on how to train your puppies. It starts with a simple crate training, followed with training to sit, come, lay down, stay, fetch, heel, and socializing your puppy.

I believe the author will add more articles in the future.
