While some of these dog training methods are firmer, some others are based on patience and love. In the end, choosing the proper dog training method will depend on your dog and on your preferences.
Dog training methods teach you to properly train your dog for specific needs. In this sense, while there are some dog training methods which are especially designed for particular competitions (such as obedience or agility training), you can also find a large variety of methods for every day living. Housebreaking a puppy or a new dog can also be considered as part of a training process.
These dog training methods always have something in common in spite of their differences: the idea of you becoming the leader of your dog. It is extremely important that your dog understands this at first in order to prevent the formation of stubborn or too independent personalities.
