Are both Jack Russell Terrier and Bullmastiff types of dogs?
Bullmastiff The Bullmastiff is a large-sized breed of domestic dog, with a solid build and a short muzzle. The Bullmastiff shares the characteristics of molosser dogs, and was originally developed by 19th-century gamekeepers to guard estates. The breed's bloodlines are drawn from the English Mastiff and the extinct Old English Bulldog. It was recognized as a purebred dog by the English Kennel Club in 1924. They are quiet dogs and very rarely bark.
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.
