The Labrador Retriever is a large, sturdy breed that typically weighs 55 to 80 pounds at maturity. Males are notably larger at 65 to 80 pounds and 22.5 to 24.5 inches tall, while females weigh 55 to 70 pounds and stand 21.5 to 23.5 inches. English (show-type) Labradors tend to be stockier and heavier than American (field-type) Labradors, so understanding your Lab's type helps set appropriate weight expectations.

Labrador Retriever puppies grow quickly and have hearty appetites from the start. Most Labs reach their adult height by 9 to 12 months but continue filling out until 12 to 14 months. Weight management is especially critical for Labs because approximately 25% carry a gene mutation (POMC) that makes them perpetually hungry and prone to obesity. Feeding a large-breed puppy food with controlled calorie content and using measured portions rather than free-feeding is essential for healthy Lab growth.
