Dog agility contests are competitive events where dogs navigate through a timed obstacle course. The course typically includes jumps, tunnels, weave poles, and other challenges that test a dog's speed, accuracy, and training. Handlers guide their dogs through the course using verbal commands and body language. These contests are designed for various skill levels and can include different breeds and sizes of dogs. Participants are judged on their performance, with points awarded for completing obstacles correctly and penalties for mistakes. Dog agility promotes teamwork between the handler and the dog, showcasing their bond and training.
