The Bulldog is a British breed of dog of mastiff type. It may also be known as the English Bulldog or British Bulldog. It is a stocky, muscular dog of medium size, with a large head, thick folds of skin around the face and shoulders and a relatively flat face with a protruding lower jaw. Selective breeding for appearance has led to increased susceptibility to health problems including brachycephaly, hip dysplasia, heat sensitivity and skin infections. The dogs may not be bred in Norway or the Netherlands, because of concerns about their quality of life.
Originally developed in England for bull-baiting, now primarily a companion breed.
The Bulldog, also known as the English Bulldog, is recognized for its characteristic wrinkled face and pushed-in nose. Its docile and friendly nature makes it a popular companion, though it requires care due to its predisposition to certain health issues such as breathing problems and joint disorders. Despite their fierce appearance, Bulldogs are generally gentle and affectionate.
