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.
Scotch Collie The Scotch Collie is a landrace breed of dog which originated from the highland regions of Scotland. The breed consisted of both the long-haired (now known as Rough) Collie and the short-haired (now known as Smooth) Collie. It is generally believed to have descended from a variety of ancient herding dogs, some dating back to the Roman occupation, which may have included Roman Cattle Dogs, Native Celtic Dogs and Viking Herding Spitzes. Other ancestors include the Gordon and Irish Setters.
