Labrador retrievers generally give birth to litters of five to ten puppies, according to the American Kennel Club. Labrador retrievers live an average of 12 to 14 years, and they weigh anywhere from 55 to 80 pounds when they reach adulthood.
Labrador retrievers are well-behaved and make excellent family pets, since they tend to be gentle and patient with children. The Labrador's easy disposition also makes it a good choice as a companion pet for an elderly person. The breed originated in Canada and has a smooth, dense coat that is easy to maintain.
Labrador retrievers are used as assistance dogs for the blind and those with autism, and they are widely used as drug detection dogs for law enforcement agencies.
