If your dog exhibits a behavior you don’t like, there is a strong likelihood that it’s something that has been reinforced before. A great example is when your dog brings you a toy and barks to entice you to throw it. You throw the toy. Your dog has just learned that barking gets you to do what he wants. You say “no,” and he barks even more. Heaven forbid you give in and throw the toy now! Why? Because you will have taught him persistence pays off. Before you know it you’ll have a dog that barks and barks every time he wants something. The solution? Ignore his barking or ask him to do something for you (like “sit”) before you throw his toy.
Every dog needs to learn to walk on a leash. Besides the fact that most areas have leash laws, there will be times when keeping your dog on a leash is for his own safety. Learn how to introduce your dog or puppy to the leash, then teach him how to walk properly on the leash, even beside you on a bike. A loose leash walk teaches your dog not to pull or lunge when on the leash, making the experience more enjoyable for both you and your dog.
