The Australian Shepherd, often known simply as the 'Aussie', is a medium-sized breed of dog that was, despite its name, developed on ranches in the United States during the 19th century. For many years, Aussies have been valued by stockmen for their versatility and trainability. While they continue to work as stock dogs and compete in herding trials, they have earned recognition in other roles due to their trainability and eagerness to please and are highly regarded for their skills in obedience. Like all working breeds, Aussies have considerable energy and drive. 3.2 Grooming. With the coat being somewhat long and wavy or curly, this breed does shed, mostly in the spring to get rid of the winter coat. The shepherd should be brushed weekly to maintain a healthy and clean coat and also to prevent matting.
