Are both Terceira Mastiff and Australian Cattle Dog Portuguese dog breads?
Australian Cattle Dog The Australian Cattle Dog (ACD), or simply Cattle Dog, is a breed of herding dog originally developed in Australia for droving cattle over long distances across rough terrain. This breed is a medium-sized, short-coated dog that occurs in two main colour forms. It has either brown or black hair distributed fairly evenly through a white coat, which gives the appearance of a "red" or "blue" dog. It should not be confused with the Australian Shepherd, a similarly named but totally different breed.
Miniature cattle Miniature cattle are found in various parts of the world. Some, such as the Dexter breed of Ireland and the Vechur of Kerala, India, are traditional breeds; others have been recently created by selective breeding. The Australian Lowline was the unexpected result of a scientific experiment. Some, but not all, miniature breeds display achondroplasia, or dwarfism.
