High-energy dogs are always ready and waiting for action. Originally bred to perform a canine job of some sort, such as retrieving game for hunters or herding livestock, they have the stamina to put in a full workday. They need a significant amount of exercise and mental stimulation, and they're more likely to spend time jumping, playing, and investigating any new sights and smells. Low-energy dogs are the canine equivalent of a couch potato, content to doze the day away. When picking a breed, consider your own activity level and lifestyle, and think about whether you'll find a frisky, energetic dog invigorating or annoying.
Number one in Americans’ preferences, Labrador Retrievers are the perfect companions for both single people and families. They’re playful, affectionate, and easy to train, so there’s no reason not to love such a dog. But having a Lab is a full-time job with no weekends off, and with vacations where you’ll be missing your dog more than you can imagine.
While individual dogs may vary, in general show-bred Labradors are heavier built, slightly shorter-bodied, and have a thicker coat and tail. Field Labradors are generally longer-legged, lighter, and more lithe in build, making them agile. In the head, show Labradors tend to have broader heads, better defined stops, and more powerful necks, while field Labradors have lighter and slightly narrower heads with longer muzzles. Field-bred Labradors are commonly higher energy and more high-strung compared to the Labrador bred for conformation showing while conformation breeds are calmer in energy, and as a consequence may be more suited to working relationships than being a "family pet". Some breeders, especially those specialising in the field type, feel that breed shows do not adequately recognise their type of dog, leading to occasional debate regarding officially splitting the breed into subtypes.
Several early descriptions of the St. John's water dog exist. In 1822, explorer W.E. Cormack crossed the island of Newfoundland by foot. In his journal he wrote "The dogs are admirably trained as retrievers in fowling, and are otherwise useful.....The smooth or short haired dog is preferred because in frosty weather the long haired kind become encumbered with ice on coming out of the water."
With the Lab’s physical strength and high energy level, early socialization and puppy training classes are vital. Gently exposing the puppy to a wide variety of people, places, and situations between the ages of 7 weeks and 4 months and beginning obedience training early on will help him develop into a well-adjusted, well-mannered adult. Puppy training classes serve as part of the socialization process and help the owner learn to recognize and correct any bad habits that may be developing. Labs are devoted, intelligent, and enthusiastic companions who need to be included in family activities.
Whatever they were called, the dogs were known for their keen sense of smell, ability to find downed birds, and speed. British visitors to Newfoundland appreciated the dogs’ abilities and brought them back to England. There, they caught the eye of the Earl of Malmesbury, who acquired some of the water-loving dogs to hunt the swamplands surrounding his estate. The Earl’s son began breeding the dogs and it was he who gave them the name Labrador. The Kennel Club in England made the breed official in 1903.
The first St. John's dog was said to be brought to England in or around 1820, but the breed's reputation had already spread to England; there is a story that the 2nd Earl of Malmesbury saw a St. John's dog on a fishing boat and immediately made arrangements with traders to have some of these dogs imported to England. These ancestors of the first labradors so impressed the Earl with their skill and ability for retrieving anything within the water and on shore that he devoted his entire kennel to developing and stabilising the breed.

It has been shown that out of all dog breeds, it is the Labrador Retriever that is most likely to be obese. In a 2016 published study it was shown that out of 310 Labradors, most were missing all or parts of the POMC gene. This gene plays a part in appetite regulation as well as indication of the amount of one's stored fat. The study concluded that the absence of that gene had a significant impact on Labrador weight and appetite. The POMC gene mutation is present in only one other breed – the Flat-Coated Retriever.
