The Golden Retriever is a relatively modern and very popular breed of dog. It was developed as a retrieving dog to use while hunting wild fowl. Today it is one of the most common family dogs as it is easy to handle, very tolerant and does not require very much of the owners, other than regular exercise, food and veterinary check-ups. It is often affectionately known as a Golden or "Yellow Retriever". Golden Retrievers are observed to be highly compatible with people and other dogs, though after the seclusion from dog life it may develop human qualities and then may not be fond of other dogs. It will bark when startled but other than that it makes a poor watchdog due to its friendly nature. Golden Retrievers are particularly valued for their high level of sociability towards people.
