The Labrador Retriever, also known as the Labrador and the Lab, is a breed of dog in the Sporting Group. This energetic and loving dog breed is a popular family pet, and they are also the most frequently used breed of dog selected for work as search and rescue dogs, guide dogs, service dogs, and therapy dogs. The Labrador Retriever was recognized by the AKC in 1917 and AKC approved in 1994.
Labrador Retrievers are relatively large with males typically weighing 65 to 80 pounds and females 55 to 70 pounds. The Lab's coat is fairly short, straight, smooth, and waterproof. They possess a straight, powerful, broad tail that is often likened to an otter's tail. The majority of the characteristics of this breed, with the exception of color, are the result of breeding to produce a working retriever.
Like any dog breed, there is a great deal of variety among Labrador Retrievers. The following characteristics are typical of the show bred or bench bred lines of this breed in the United States, and are based on the American Kennel Club standard. Significant differences between United States and United Kingdom standards are noted.
Labrador Retrievers are a well balanced and versatile dog breed that make excellent pets. As a rule, they are not excessively prone to being territorial, pining, insecurity, aggression, destructiveness, hypersensitivity, or other difficult traits which sometimes manifest in a variety of breeds. Labradors have a reputation as a very mellow breed and an excellent family dog, including a good reputation with children of all ages and other animals.
Labrador Retrievers are generally a healthy breed, with good medical care they should have relatively few major problems. Labs are somewhat prone to hip and elbow dysplasia, especially the larger dogs, though not as much as some other breeds. Eye problems are also possible in some Labs.
