Bulldogs are medium-sized, muscular dogs known for their loose, wrinkled skin and pushed-in nose. Originally bred for bull-baiting, they are now gentle and affectionate companions. Bulldogs have a distinctive gait due to their stocky build and short legs. They thrive in moderate climates and require minimal exercise.

The Bulldog, also known as the English Bulldog, is a domesticated breed that originated in the British Isles. It was initially developed in England for bull-baiting, a popular sport in medieval times.

As a domesticated breed, Bulldogs are suited to human-inhabited environments rather than wild habitats. They prefer moderate climates and can struggle in extreme heat due to their brachycephalic (short-nosed) structure, which makes breathing difficult in hot weather.

The Bulldog does not occupy a natural ecological niche in the wild, as it is a domesticated breed developed for companionship and show purposes. Its role is primarily as a household pet, thriving in environments where it receives regular care and attention from humans.
