Labrador Retriever size questions
How big does a Labrador Retriever get?
The American Kennel Club gives 65 to 80 lb (29 to 36 kg) for males and 55 to 70 lb (25 to 32 kg) for females. Individual dogs can fall outside a breed range, and a mix or a dog from working lines may be larger or smaller.
When is a Labrador Retriever fully grown?
On this curve a male reaches half of adult weight at about 19 weeks (4 months), 90 % at about 42 weeks (10 months) and 95 % at about 59 weeks (14 months). On this curve a female reaches half of adult weight at about 18 weeks (4 months), 90 % at about 42 weeks (10 months) and 95 % at about 58 weeks (13 months). These ages come from the shape of the published growth chart for large dogs, scaled to the AKC weight, so they describe a typical dog, not a particular one.
How much should a Labrador Retriever puppy weigh at 6 months?
A typical male is about 49 lb (22 kg) and a female is about 45 lb (20 kg) at 26 weeks on this curve. The range for healthy puppies is wide, so use the calculator above with your own puppy’s weight.
