Question: Are Labrador Retrievers and Schweizer Laufhund both types of dogs?

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.

Soft mouth: The term soft mouth is used by breeders and users of hunting dogs to refer to a behavioral tendency to pick up, hold, and carry quarry gently.  It is not a preferred characteristic of terriers and ratters, who are expected to roughly shake and mangle pests such as rats and snakes in order to kill them quickly and efficiently.  It is desirable in gundogs such as retrievers and spaniels which are expected to produce quarry intact and in good condition, and is a notoriously difficult behavior to teach to a dog without an inborn temperament to do so.  As a result, breeders and users of gun dogs arrived on this term to describe a characteristic important to this enterprise.  Dogs breeds known for producing more soft-mouthed individuals include Golden Retrievers, Cocker Spaniels, Poodles, and Gordon Setters, but in any litter some individuals may be much less soft-mouthed than others, as there may be relatively soft-mouthed individuals in a litter of even classically hard-mouthed breeds such as Jack Russell Terriers or Mastiffs.

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.

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.

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.  They are sponsored by the Motion Picture Association of America (MPAA) and Federation Against Copyright Theft (FACT) as part of an initiative to combat copyright infringement of film DVDs.

Gun dog: Gun dogs, or bird dogs, are types of hunting dogs developed to assist hunters in finding and retrieving game, usually birds. Gun dogs are divided into three primary types: retrievers, flushing dogs, and pointing breeds.  Some kennel clubs define a Gundog Group for gun dogs, while other kennel clubs include them in the Sporting Group.

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).

Golden Retriever: The Golden Retriever is a large-sized breed of dog bred as gun dogs to retrieve shot waterfowl such as ducks and upland game birds during hunting and shooting parties, and were named 'retriever' because of their ability to retrieve shot game undamaged.  Golden Retrievers have an instinctive love of water, and are easy to train to basic or advanced obedience standards.  They are a long-coated breed, with a dense inner coat that provides them with adequate warmth in the outdoors, and an outer coat that lies flat against their bodies and repels water.  Golden Retrievers are well suited to residency in suburban or country environments.  Although they need substantial outdoor exercise, they should be housed in a fenced area because of their instinctual tendency to roam.  They shed copiously, particularly at the change of seasons, and require fairly regular grooming.

Schweizer Laufhund: The Schweizer Laufhund is a breed of hound dog, originally from Switzerland.
