Agility courses are specially designed obstacle courses for dogs that test their speed, coordination, and training. These courses typically include various challenges such as jumps, tunnels, weave poles, and seesaws. The goal is for the dog to navigate the course as quickly and accurately as possible, guided by their handler. Competitions often take place in dog agility events, where teams of handlers and their dogs showcase their skills. Agility training can enhance a dog's physical fitness and mental stimulation, making it a popular activity among pet owners and trainers alike.
