How big is a wolf pup?

Wolf pups are born quite small, weighing only about 1 pound (0.45 kilograms) and measuring about 10 inches (25 centimeters) in length. They grow quickly, however, and by the time they are 6 months old, they can weigh up to 30 pounds (14 kilograms) and measure up to 3 feet (0.9 meters) in length.
