How big does a Labrador Retriever get?
An adult male Labrador Retriever usually weighs 65–80 lb (29–36 kg) and an adult female 55–70 lb (25–32 kg). Labs grow fast and love food, so they are prone to puppy chubbiness. Keep them lean while their joints develop; most reach adult height by about 12 months and fill out until around 18 months.
When is a Labrador Retriever fully grown?
As a large breed, a Labrador Retriever typically reaches its adult weight at about 18 months. Height usually finishes first; chest and muscle keep filling out for a while after.
