sentences: The Australian Stumpy Tail Cattle Dog is a naturally bobtailed or tailless, medium-sized breed of Cattle Dog (not to be confused with the Australian Cattle Dog, aka "Queensland Heeler").
 The Australian Stumpy Tail Cattle Dog was developed in Australia to herd cattle, and descends from crosses between European herding dogs and the Australian dingo.
 The name is spelled both with hyphenation, as Australian Stumpy-Tail Cattle Dog, and without, and the shorter name Stump Tail Cattle Dog is also sometimes applied.
A natural bobtail is an animal's tail which due to a mutated gene grows unusually short or is missing completely.
 The genes for the shortened tail may be dominant or recessive.
Argulus japonicus, common name Japanese fishlouse or Japanese fish louse, is a species of crustacean in the family Argulidae, the fish lice.
 This species is light brown in colour and may be between 4 and 9 mm long and 3 to 6 mm wide.
 It has a stumpy tail, and is shaped somewhat like a round shield.
Myosin-1, also known as 'striated muscle myosin heavy chain 1', is a protein that in humans is encoded by the "MYH1" gene.
 This gene is most highly expressed in fast type IIX/D muscle fibres of vertebrates and encodes a protein found uniquely in striated muscle; it is a class II myosin with a long coiled coil tail that dimerizes and should not be confused with 'Myosin 1' encoded by the MYO1 family of genes ("MYO1A-MYO1H").
 Class I MYO1 genes function in many cell types throughout biology and are single-headed membrane-binding myosins that lack a long coiled coil tail.
Holodactylus africanus is a species of gecko that is commonly found in Eastern Africa.
 The gecko has a big head, thin body, stumpy tail, and has tan and brown bands.
 The adults are 3 and a half to four inches long.
Tail wagging by dogs is the behavior of the dog observed as its tail moves back and forth in the same plane.
 It is considered a social signal.
 Tail wagging by dogs can be described by its vigorous movement or even just the slightest movement of the tip of its tail.
 Other dogs wag their tail in a circular motion, and even when the tail is between their legs or the dog is on its back.
 The behavior of a dog can not always be an indication its friendliness.
 When a dog wags its tail, most people interpret this as the dog expressing happiness and friendliness.
 Though indeed tail wagging can express these positive emotions, tail wagging is also an indication of fear, insecurity, challenging of dominance, establishing social relationships or a warning that the dog may bite.
The American Bobtail is an uncommon breed of domestic cat which was developed in the late 1960s.
 It is most notable for its stubby "bobbed" tail about one-third to one-half the length of a normal cat's tail.
 This is the result of a cat body type genetic mutation affecting the tail development, similar to that of a Manx cat.
 The breed is not related to the Japanese Bobtail despite the similar name and physical type—the breeding programs are entirely unrelated, and the genetic mutation causing the bobbed tail are known to be different because the mutation causing the American Bobtail's tail is dominant, whereas the Japanese Bobtail tail mutation is recessive.
The Cão Fila de São Miguel (Portuguese: ] ) (frequently translated into English as the "São Miguel Cattle Dog" or "Cattle Dog of São Miguel Island", but other names, such as "Azores Cattle Dog", may be used) is a dog breed of molosser type originating on São Miguel Island in the Azores, an island chain which is one of the autonomous regions of Portugal.
 The breed was originally used for working with cattle.
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.
The Halls Heeler was a dog bred by Thomas Simpson Hall to herd cattle on the Hall family's extensive properties in north-western New South Wales in the 19th century.
 On "Dartbrook Station", in the Upper Hunter Valley, Hall selectively crossed the offspring of Northumberland Drover's Dogs (Border Collie lineage) that he had imported, with progeny of dingoes that he had tamed.
 By 1840 he had bred the type of dog that he needed to control cattle on the massive runs that his family owned, and until he died in 1870 few of these dogs were owned and used by anyone outside the Hall family and their workers.
 However the death of Thomas Hall and the break-up of the Hall estate coincided with the development of the dog show, and an interest in breeding dogs to specific criteria or standards.
 The Halls Heeler was further developed into two contemporary dog breeds the Australian Cattle Dog and the Australian Stumpy Tail Cattle Dog.
 The name is spelled both with the possessive apostrophe, as Hall's Heeler, and without.
