The dog (Canis familiaris or Canis lupus familiaris) is a domesticated descendant of the wolf. Also called the domestic dog, it is derived from the extinctPleistocene wolf; the gray wolf is the dog's closest living relative. The dog was the first species to be domesticated by humans. Experts estimate that hunter-gatherers domesticated dogs more than 15,000 years ago, which was before the development of agriculture. Due to their long association with humans, dogs have expanded to a large number of domestic individuals and gained the ability to thrive on a starch-rich diet that would be inadequate for other canids.
They were an essential part of traditional Tahitian society; their meat was included in Tahitian cuisine and other parts of the dog were used to make tools and ornamental clothing. Dogs were fed a vegetarian diet and served during feasts as a delicacy. European explorers were the first outsiders to observe and record their existence, and they were served to early explorers including Captain James Cook. The Tahitian Dog disappeared as a distinct breed after the introduction of foreign European dogs. (Full article...)
The Labrador Retriever ("Labrador" or "Lab" for short), is a retriever, and is the most popular breed of dog (by registered ownership) in the United States, Canada, and the United Kingdom. The breed is friendly, intelligent, energetic and good natured, making them excellent companions and working dogs. Labrador Retrievers are known to be one of the fastest-learning breeds of dog and respond well to praise and positive attention. The steady temperament of Labs and their ability to learn quickly make them an ideal breed for assistance dogs as well as search and rescue, detection, and therapy work.
A dog breed is a particular type of dog that was purposefully bred by humans to perform specific tasks, such as herding, hunting, and guarding. Dogs are the most variable mammal on Earth, with artificial selection producing upward of 360 globally recognized breeds. These breeds possess distinct traits related to morphology, which include body size, skull shape, tail phenotype, fur type, body shape, and coat colour. However, there is only one species of dog. Their behavioral traits include guarding, herding, and hunting, and personality traits such as hyper-social behavior, boldness, and aggression. Most breeds were derived from small numbers of founders within the last 200 years. As a result of their adaptability to many environments and breedability for human needs, today dogs are the most abundant carnivore species and are dispersed around the world.
A dog breed will consistently produce the physical traits, movement and temperament that were developed over decades of selective breeding. For each breed they recognize, kennel clubs and breed registries usually maintain and publish a breed standard which is a written description of the ideal specimen of the breed. Other uses of the term breed when referring to dogs include pure breeds, cross-breeds, mixed breeds and natural breeds. (Full article...)
