Dog agility is a competitive sport where dogs navigate through a timed obstacle course. Handlers guide their dogs through various challenges, including jumps, tunnels, and weave poles, showcasing the dog's speed and obedience. The sport emphasizes teamwork and communication between the dog and handler. Competitions are held at different levels, allowing dogs of all breeds and sizes to participate. Agility trials are often organized by clubs and associations, promoting the sport and providing opportunities for training and competition.
