How quickly do wolf pups grow?
Very. Wolf pups weigh about 1 pound at birth. At four weeks they weigh about 5 pounds and at two months old they weigh 20 pounds. In their first fourteen weeks of life, pups put on between 2.6 and 3.3 pounds per week. At six months old it’s hard to distinguish them from adults, and by one year of age they are close to their adult size. By the age of two, a wolf is fully mature.
