Question: Poitevin and Moscow Water Dog, are breeds of what?
Context: The Poitevin, known as the Chien de Haut-Poitou until 1957, is a breed of dog used in hunting as a scenthound, from the province of Poitou.  This predominantly pack hound was created in the 17th century specifically to hunt wolves.

The Poitevin, also called Mulassier ("mule-breeder"), Poitevin Mulassier or Trait Mulassier is a draft horse from the Poitou area of France.  It is a late-maturing breed with strong bones, known for its calm nature.  It is found in many solid coat colors, the result of crossbreeding with several other European draft breeds throughout its history, and is the only French draft horse to be found in bay dun.  Today, Poitevins are used mainly for driving, although some are used for riding and equine therapy. A grief therapy dog (also known as an emotional support dog, companion dog, or comfort dog) is a form of animal-assisted therapy.  Dogs have been proven to be able to assist people in overcoming grief, which has led to a recent rise in the use of therapy dogs; although animal-assisted therapy theory has been around since World War II.  Grief therapy dogs can be found in locations such as funeral homes, hospitals, nursing homes, schools, and hospices, and may provide support in situations such as funeral services, counseling sessions, and disaster relief.  Popular breeds used as therapy dogs include the Portuguese Water Dog, Bernese Mountain Dog, St. Bernard, and Golden Retriever. The Moscow Water Dog, also known as the Moscow Diver, Moscow Retriever or Moskovsky Vodolaz, is a little-known dog breed derived from the Newfoundland, Caucasian Shepherd Dog and East European Shepherd.  It is now extinct, but was used in the development of the  Black Russian Terrier.  The Moscow Water Dog was produced only by the Red Star Kennels, the state operated organization chartered to provide working dogs for the armed services. The Tweed Water Spaniel, or Tweed Spaniel, is a breed of dog extinct since the 19th century.  It is best known for being involved in the early development of the modern Curly Coated Retriever and Golden Retriever breeds of dogs.  They were described as a generally brown athletic dogs from the area around Berwick-upon-Tweed near the River Tweed and close to the Scottish Borders.  A type of water dog, the breed was not well known outside the local area.  This breed may have been created by crossing local water dogs with imported St. John's water dog, another breed which is also now extinct. The Spanish Water Dog (perro de agua español ) breed dates back several hundred years and has its origins most likely in Turkey from where it was imported into Spain as a general purpose sheepdog and guard.  It is also used sometimes as a gundog, and is skilled at retrieval from water.  The SWD has strong genetic links to other ancient water breeds such as the Portuguese Water Dog, the French Barbet and the Irish Water Spaniel. The Cantabrian Water Dog (Spanish: perro de agua cantábrico ) is a landrace breed of dog developed in the coast of Cantabria, northern Spain, as an assistant to fishermen.

The Wetterhoun (FCI No.221, translated into English as the Frisian Water Dog) is a breed of dog traditionally used as a hunting dog for hunting small mammals and waterfowl in the province of Fryslan in the Netherlands.  The name of the dog comes from the West Frisian "Wetterhûn" meaning "water dog."  Plural of Wetterhoun is Wetterhounen in Dutch.  The breed may also be called the "Otterhoun" (not to be confused with the Otterhound) or "Dutch Spaniel", although it is not a Spaniel-type dog. The Poitou donkey or Poitou ass (French: Baudet du Poitou ), also called the Poitevin donkey or simply the Poitou, is a breed of donkey originating in the Poitou region of France.  It is one of the largest donkey breeds, and was selected for size so that it could be used for the production of large working mules, in conjunction with the Poitevin horse breed.  It is known for its distinctive coat, called a "cadanette", which hangs in long, ungroomed cords.  Breeders originally prized the coats highly, but today, many Poitou donkeys are shorn for hygiene reasons.
