Which statement best describes a characteristic of working dog breeds?

• A. Smaller size, kept as pets
• B. Larger size, used as guard dogs and messenger dogs
• C. Used for pointing and retrieving game
• D. Mixed group of dogs

Answer: (B)

Working dog breeds are defined by the tasks they were bred to perform—strength, endurance, and trainability for demanding jobs. A hallmark of this group is larger, powerful dogs that have been used for protection and practical work, such as guarding property or carrying messages in historical contexts. That makes the statement describing these breeds as larger in size and used for guard duties and messenger work the best fit, since it directly reflects their traditional roles and capabilities.

Smaller size and being kept as pets describes companion or toy breeds, which aren’t the typical functional emphasis of working dogs. Pointing and retrieving describes sporting or hunting breeds, not primarily working dogs. A mixed group of dogs doesn’t capture a defining trait of the Working Group.
