Context paragraphs:
List of Labrador Retrievers: This list of Labrador Retrievers covers notable individual dogs that belong to this breed.  The Labrador retriever is the most popular breed of dog (by registered ownership) in both the United States and the United Kingdom.  The breed is exceptionally affable, intelligent, energetic and good natured, making them excellent and popular pets, companions and working dogs.  They have a high work ethic Common working roles for Labradors include: hunting, tracking and detection, disabled-assistance, carting, and therapy work.  Approximately 60–70% of all guide dogs in the United States are Labradors.

.243 Winchester: The .243 Winchester (6×52mm) is a popular sporting rifle cartridge.  Initially designed as a target/varmint round, it may be used for animals such as coyote, blacktail deer, whitetail deer, mule deer, pronghorn, and wild hogs.  It can also be used against larger animals such as black bear or elk but is sometimes said to be "too light" for such large animals.  Rounds of at least 90 grains are better suited for hunting larger animals while rounds less than 90 grains are more suitable for varmints.  The .243 is based on a necked down .308 cartridge case.  It is very popular with target shooters, Metallic Silhouette, and long range shooters, because of its accuracy and low recoil.

Lithuanian Hound: The Lithuanian Hound has been traditionally used to hunt hare, fox, and boar.  The breed is mentioned in the Statutes of Lithuania (16th century).  It is believed that it comes from the mixing of bloodhounds with several other hound breeds.  Once a popular breed in Lithuania, the population decreased to 78 individuals after World War II.  Thanks to several enthusiasts, the hound was revived, standardized, and the number of registered and documented dogs reached around 350 in 1987.  After the dissolution of the Soviet Union, the breed decreased to around 150 individuals by 1998.  The decrease in popularity is explained by changing hunting habits: the Lithuanian Hound is best suited for hunting large animals in large open areas, but modern hunting plots are decreasing in size.  The Lithuanian Cynological Society plans to register the breed with the Fédération Cynologique Internationale (FCI).

Weimaraner: The Weimaraner ( ) is a large dog that was originally bred for hunting in the early 19th century.

Iris cyst: An iris cyst, or uveal cyst, is a small hollow structure either attached to the iris of the eye or floating free in the anterior chamber.  An iris cyst is composed of a single cell layer of epithelium and is filled with fluid.  It is most commonly seen as secondary to inflammation in the eye, especially with canine glaucoma.  They are most commonly seen in dogs. Golden Retrievers, Labrador Retrievers, and Boston Terriers are the most commonly affected breeds.  Iris cysts also occur in cats and horses.  The cysts are usually free floating in dogs, attached to the pupillary margin in cats, and present in the interior of the iris (especially blue irises) in horses.

Lucky and Flo: Lucky and Flo are a pair of black Labrador retrievers notable for being the first animals trained to detect optical discs by scent.

Exercise-induced collapse: Exercise-induced collapse (EIC) is a genetic syndrome, predominantly occurring in mixed breed dogs related to several retriever breeds as well as purebred Labrador Retrievers but also seen in Chesapeake Bay Retrievers and Curly Coated Retrievers, Boykin spaniels, Cocker spaniels, German wire-haired pointers, Old English Sheepdogs, Bouvier des Flanders, Pembroke Welsh corgis and Clumber Spaniels (Verified 2015 by Laboklin in the UK).

Labrador Retriever: The Labrador Retriever, also Labrador, is a type of retriever-gun dog.  The Labrador is one of the most popular breeds of dog in the United Kingdom and the United States.

Retriever: A retriever is a type of gun dog that retrieves game for a hunter.  Generally gun dogs are divided into three major classifications: retrievers, flushing spaniels, and pointing breeds. Retrievers were bred primarily to retrieve birds or other prey and return them to the hunter without damage; retrievers are distinguished in that nonslip retrieval is their primary function.  As a result, retriever breeds are bred for soft mouths and a great willingness to please, learn, and obey.  A soft mouth refers to the willingness of the dog to carry game in its mouth without biting into it.  "Hard mouth" is a serious fault in a hunting dog and is very difficult to correct.  A hard-mouthed dog renders game unpresentable or at worst inedible.
