Is your pup’s behavior out of bounds? In an exclusive excerpt from his new book, the Dog Whisperer teaches you how to set limits—and stick to them!

Being able to set and communicate boundaries is one of the most important roles that you play as your puppy’s pack leader.

English bulldogs often exhibit "bullying" behavior. It is important to discourage this at an early age. However, you can harness this trait and use it to your advantage. Consider enrolling your puppy in Guard Dog School. That way, you will have more control over the behavior, but also receive a great benefit from it!
