The Jack Russell Terrier is named for the man who developed the breed during the 1800s, Jack Russell. These dogs are known for their energetic nature. They’re also very smart and at least a bit determined to do things their own way which makes them tend to try to take over as master of the house. Of course, the Jack Russell is so cute, many masters let them – at least to some extent. In 2003, the American Kennel Club officially changed the name to Parson Terrier, though most people continue to call them Jack Russells.
