Dogs are perhaps the most common household pet in the world. After all, they are incredibly friendly creatures and can do many different things. Some are even specially trained to help people with disabilities, such as guiding the blind. Dogs can even get incredibly good at agility sports, hunting, and more! Dogs are also common in fiction, such as Snoopy, Lassie, and even the Tramp. Are you a dog lover? Do you have a dog? Chances are if the answer is yes, you know a lot about your dog.
