Many Labrador prospects and owners often ask themselves the question: How big does a Labrador Retriever get? Here is a detailed explanation of how big a Labrador Retriever grows and how long it takes to reach its maximum size.

A Labrador Retriever usually grows 14 to 18 months and is therefore fully grown. A male reaches a size of 56 to 58 cm with a weight of 29 to 36 kg. A female Labrador is 54 to 55 cm tall and weighs 25 to 32 kg.

A Labrador Retriever needs special puppy or young dog food in the growth phase. When buying, you should make sure that the packaging says Puppy and not Adult. There is now very good dog food on the market. We recommend the Royal Canin special food for puppies:

Important: The amount of feed, composition (wet / dry feed) should be agreed with the breeder or veterinarian.

Growth in Comparison

How does the Labrador Retriever growth rate compare with the other dog breeds?

  • Small breeds of dogs like the Chihuahua are fully grown in approximately 6 months.
  • Medium-sized dog breeds like the Shiba Inu grow around 9 months.
  • Large dog breeds such as the Golden Retriever or the German Shepherd Dog are fully grown at around 14 months.
  • Very large dogs like the St. Bernard are fully grown at around 18 months.

In general, one can say: 

A dog is fully grown when a bitch is in heat and the male starts to lift his leg. However, it can take a little longer until the final size is reached. This is faster with small breeds than with large breeds.
