how long do labs grow for
Labrador retrievers reach their full height when they are between 12 and 18 months old, but they continue building muscle and filling out until they are 2 years old. How quickly Labs grow depends on the individual dog.
How much should a Labrador retriever weigh? The American Kennel Club states that a standard fully grown adult male Lab stands 22 1/2 to 24 1/2 inches tall and weighs between 65 and 80 pounds. Female Labs grow to 21 1/2 to 23 1/2 inches tall and weigh between 55 and 70 pounds. Lab puppies need good nutrition for proper growth. Underfed puppies don't grow as well as those that are well fed, and a serious illness can stunt a puppy's growth.
