1. Dogs

Dogs are the most popular pet in the United States. There are many reasons for that. Dogs are immensely loyal and protective. Research has proven that the loyalty of a dog to his master is second to none. They are generally affectionate with kids and their owners. Some dogs are better with kids and can be trained better than others. Dogs will know when the master is low and will playfully try to distract them from the surly mood. According to The American Kennel Club, the Labrador Retriever is the most popular dog breed in America today.
