The Labrador Retriever, Labrador or just Lab, is a medium-large breed of retriever-gun dog. The Labrador is the most popular breed of dog in many nations. However, Field Labradors should still be proportional and fit within American Kennel Club standards. With Field Labradors, excessively long noses, thin heads, long legs, and lanky frames are not considered standard. These two types are informal and not codified or standardised; no distinction is made by the AKC or other kennel clubs, but the two types come from different breeding lines. Australian stock also exists; though not seen in the West, they are common in Asia. These dogs are also very good with children. Body: The body should have a powerful and muscular build.The tail and coat are designated 'distinctive [or distinguishing] features' of the Labrador by both the Kennel Club and AKC. The AKC adds that 'true Labrador Retriever temperament is as much a hallmark of the breed as the 'otter' tail.'
