Are the Briard and Plott Hound both companion dogs?
no
Briard
The Briard is an ancient breed of large herding dog, originally from France.
 A Briard-type dog appears in Gaston Febus' "Livre de chasse" ("Book of the Hunt"), written in the late 14th century.
 According to legend, about the same time, a Briard fought a judicial duel with Robert Macaire to avenge its owner's murder, Aubry of Montdidier.
 Charlemagne, Napoleon, Thomas Jefferson, and Lafayette are all said to have owned Briards.
 It became popular after the Paris dog show of 1863, after the breed had been fixed, with crosses with the Beauceron and the Barbet.
 During the First World War, the Briard was used, almost to the point of extinction, by the French army as a sentry, messenger, and to search for wounded soldiers.
 The Briard's modern-day roles include police, military and search-and-rescue work, as well as companion dog.
Plott Hound
The Plott Hound is a large scent hound, originally bred for hunting boar.
Griffon
Griffon is a type of dog - a collection of breeds that were originally hunting dogs.
 There are three lines of the griffon type recognized by the Fédération Cynologique Internationale (FCI): the griffon vendéens, the wirehaired pointers, and the "smousje" (Belgian companion dogs or Dutch Smoushond).
 The griffon type is characterized by rough or wire-hair. List of U.S. state dogs
Twelve states of the United States have designated an official state dog breed.
 Maryland was the first state to name a dog breed as a state symbol, naming the Chesapeake Bay Retriever in 1964.
 Pennsylvania followed the year after, naming the Great Dane as its official breed.
 Dog breeds are mostly affiliated with the states that they originated in.
 North Carolina chose the Plott Hound as it was the only dog breed indigenous to the state. Teddy Roosevelt Terrier
The Teddy Roosevelt Terrier is a small to medium-sized American hunting terrier.
 Lower-set with shorter legs, more muscular, and heavier bone density than its cousin the American Rat Terrier.
 There is much diversity in the history of the Teddy Roosevelt Terrier breed and it shares a common early history with the American Rat Terrier, Fox Paulistinha and Tenterfield Terrier.
 It is said the Rat Terrier background stems from the terriers or other dogs that were brought over by early English and other working class immigrants.
 Since the breed was a farm, hunting and utility dog there was little to no planned breeding other than breeding dogs with agreeable traits to each other in order to produce the desired work ethic in the dog.
 It is assumed that the Feist (dog), Bull Terrier, Smooth Fox Terrier, Manchester Terrier, Whippet, Italian Greyhound, the now extinct English White Terrier, Turnspit dog and or Wry Legged Terrier all share in the Teddy Roosevelt Terrier's ancestry.
 These early Ratting Terriers were then most likely bred to the Beagle or Beagle cross bred dogs (for increased scenting ability) and other dogs.
 Maximizing the influences from these various breeds provides the modern Teddy Roosevelt Terrier with a keen sense of awareness and prey drive, an acute sense of smell and a very high intellect.
 Although they tend to be aloof with strangers they are devoted companion dogs with a strong desire to please and be near their owners side at all times. Bichon
Bichon is the name for a type of related non-sporting category dog breeds.
 They vary in appearance, but all have tails curled over their back, fur that doesn't readily shed (actually hair, not fur), has a short snout, drop ears, and large, dark eyes.
 They were all bred to be amiable companion dogs and have a friendly, alert temperament.
 Their life expectancy is 15 years or more.
 The Bichon Frise, a type of bichon, is sometimes simply called a Bichon. Belgian Shepherd
The Belgian Shepherd (also known as the Belgian Sheepdog or Chien de Berger Belge) is a breed of medium-to-large-sized herding dog.
 It originated in Belgium and is similar to other sheep herding dogs from that region, including the Dutch Shepherd, the German Shepherd, the Briard, and others.
 Four types have been identified by various registries as separate breeds or varieties: Groenendael, Laekenois, Tervuren, and Malinois. Andalusian Hound
The Andalusian hound (Spanish: "Podenco andaluz" ) is a dog breed originating in Spain, especially Andalusia.
 These dogs are similar to other Iberian breeds such as the Ibizan Hound, the Portuguese Podengo, the Podenco Canario and the Maneto.
 In the Iberian Peninsula there are cave paintings representing dogs with a strong resemblance to these races.
 Dogs very similar to these, including the Cirneco dell'Etna and Pharaoh Hound, have been bred in much of the Mediterranean basin since ancient times.
 Despite the widespread belief that the podencos were introduced into Spain some 3,000 years ago by the Phoenicians, recent genetic studies have concluded that these dogs actually have a close genetic relationship with other European hunting dogs and are no more "primitive" than the others. Companion Group
Companion Group is the name of a breed group of dogs, used by kennel clubs to classify a defined collection of dog breeds, and does not necessarily include all dogs kept as companions or pets.
 In some kennel clubs the "Companion Group" is called the "Companion and Toy Group".
 The international kennel club association, the Fédération Cynologique Internationale has companion dogs in Group 9 "Companion and Toy Dogs". Star (dog)
