Two platforms, usually about 3 feet (1 m) wide by 8 to 9 feet (3 m) long, hinged together and raised so that the hinged connection is between five and six-and-a-half feet above the ground (depending on the organization), forming roughly an A shape. The bottom 36 to 42 inches (1 m) of both sides of the A-frame are painted a light colour, usually yellow, forming the contact zone, into which the dog must place at least one paw while ascending or descending. Most sanctioning organizations require that A-frames have low, narrow horizontal slats all along their length to assist the dog's grip going up and down.

Three 8 to 12 ft (3 to 4 m) planks, 9 to 12 inches (25 to 30 cm) wide, connected at the ends. The centre plank is raised to about 4 feet (1.2 m) above the ground, so that the two end planks form ramps leading up to and down from the centre plank. This obstacle also has contact zones. Most sanctioning organizations also require slats on the dogwalk ramps; a slatless dogwalk looks almost the same as a teeter-totter to a dog approaching it head-on.

A 10 to 12 foot (3 to 4 m) plank supported just off-centre about 2 feet (60 cm) above the ground so that the same end always returns to the ground. This also has contact zones. The balance point and the weight of the plank must be such that even a tiny dog, such as a Papillion or Chihuahua, can cause the high end of the teeter-totter to descend to the ground within a reasonable amount of time, specified by the sanctioning organization's rules (usually about 2 seconds). Smaller dogs get more time to run a course, and this is one reason why it can take them longer than it takes larger dogs.

Picture a 4 foot (1.2 m) high table obstacle with dogwalk ramps descending from the centre of all four sides. The dog must ascend the correct ramp and then possibly change direction at the top to descend the ramp indicated by the handler. This has not been a commonly used obstacle and not all organizations have allowed it.

A solid tube, 10 to 20 feet (3 to 6 m) long and about 2 feet (60 cm) in diameter, through which the dog runs. The tunnel is constructed of flexible vinyl and wire so that it can be configured in a straight line or curved.

A barrel-like cylinder with a tube of fabric attached around one end. The fabric extends about 8 to 12 feet (3 to 4 m) and lies closed until the dog runs into the open end of the chute and pushes his way out through the fabric tube.

Two upright bars supporting a horizontal bar over which the dog jumps. The height is adjusted for dogs of different heights. The uprights can be simple bars or can have wings of various shapes, sizes, and colours.

Two or three sets of uprights, each with horizontal poles. The Double can have parallel or ascending horizontal bars; the triple always has ascending bars. The spread between the horizontal bars is sometimes adjusted for the height of the dog.

Instead of horizontal bars, the jump is a solid panel from the ground up to the jump height. This is usually constructed of several short panels that can be removed to adjust the height for different dog heights.

A set of four or five slightly raised platforms that form a broad area over which the dog must jump without setting feet on any of the platforms. Length is adjusted for dog's height.

This is just what it sounds like: A tire shape suspended in a frame. The dog must jump through the opening of the tire, which varies between about 18 and 24 inches (450 to 600 mm). The tire must be wrapped with tape so that there are no openings or uneven places in which the dog could catch. The height is adjusted for dogs of different heights.

An elevated square platform about 3 feet (1 m) across onto which the dog must jump and pause, either sitting or in a down position, for a certain period counted out by the judge, usually about 5 seconds. The height ranges from about 8 to 30 inches (20 to 75 cm) depending on the dog's height.

Similar to a slalom, this is a series of upright poles, each about 3 feet (1 m) tall and spaced about 20 inches (50 cm) apart, through which the dog weaves. Varies from 5 to 12 poles at one time. The dog must always enter with the first pole to his left and must not skip poles.
