Labradors are a well-balanced, friendly and versatile breed, adaptable to a wide range of functions as well as making very good pets. As a rule they are not excessively prone to being territorial, pining, insecure, aggressive, destructive, hypersensitive, or other difficult traits which sometimes manifest in a variety of breeds. As the name suggests, they are excellent retrievers. Labradors instinctively enjoy holding objects and even hands or arms in their mouths, which they can do with great gentleness (a Labrador can carry an egg in its mouth without breaking it). They are also known to have a very soft feel to the mouth, as a result of being bred to retrieve game such as waterfowl. They are prone to chewing objects (though they can be trained out of this behaviour). The Labrador Retriever's coat repels water to some extent, thus facilitating the extensive use of the dog in waterfowl hunting.
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), but some lines (particularly those that have continued to be bred specifically for their skills at working in the field rather than for their appearance) are particularly fast and athletic. Their fun-loving boisterousness and lack of fear may require training and firm handling at times to ensure it does not get out of hand—an uncontrolled adult can be quite problematic. Females may be slightly more independent than males. Labradors mature at around three years of age; before this time they can have a significant degree of puppyish energy, often mislabelled as being hyperactive. Because of their enthusiasm, leash-training early on is suggested to prevent pulling when full-grown. Labs often enjoy retrieving a ball endlessly and other forms of activity (such as agility, frisbee, or flyball). Reflecting their retrieving bloodlines, almost every Lab loves playing in water or swimming.
Although they will sometimes bark at noise, especially noise from an unseen source ("alarm barking"), Labs are usually not noisy or territorial. They are often very easygoing and trusting with strangers, and therefore are not usually suitable as guard dogs.
Labradors have a well-known reputation for appetite, and some individuals may be highly indiscriminate, eating digestible and non-food objects alike. They are persuasive and persistent in requesting food. For this reason, the Labrador owner must carefully control his/her dog's food intake to avoid obesity and its associated health problems.
The steady temperament of Labs and their ability to learn make them an ideal breed for search and rescue, detection, and therapy work. Their primary working role in the field continues to be that of a hunting retriever.
