Dogs learn through repetition, and consistency. The one way for them to learn training is reward based. Giving your dog something, they really like such as food, toys or praise when they show a specific behavior means that they are more likely to do it again.
It’s important to find out what your dog really enjoys and what their desired things are. Favorite treats are often small pieces of meat or cheese. The better the reward the more your dog will enjoy training and learning.
