Any of several breeds of gun dog, bred especially to scent the position of game and indicate it by standing, nose pointed toward it, often with one forefoot raised, in silence. English pointers have smooth coats, mainly white mixed with black, tan, or dark brown. They stand about 60 cm/24 in tall, and weigh 28 kg/62 lb.
A very similar breed, the German short-haired pointer, was developed in the 19th century to point and also to pursue game.
The Weimeraner is another pointing breed.
