The Labrador is one of the most popular registered pedigree dog breeds in the UK. Whatever their colour, Labs are known as loving, gentle and ideal family dogs.
Labrador puppies are surprisingly small at birth. The average weight of a puppy in a litter of six is 454 g (1 lb) or less.
During the first eight weeks of life, the average Labrador puppy gains approximately 900 g (2 lb) per week. By the time the puppy has reached eight weeks, he should be approximately 7 kg (16 lb).
Between eight weeks and six months (26 weeks), the new owner can expect this rate of growth to continue. By six months, a healthy Labrador puppy should weigh 22 to 27 kg (50 to 60 lb).
Between six months and one year, the growth rate of the Labrador will slow. At one year, male Labradors should weigh 29 to 36 kg (65 to 80 lb) while females should weigh 24 to 31 kg (55 to 70 lb).
By the time a Labrador is three years old, he should have reached his adult weight. Between years one and three, the Labrador should gain between 2 kg (5 lb) and 4.5 kg (10 lb).
