The domestication of the wolf, or dog, as the first domesticated animal, began at the end of the last ice age. Numerous finds of dog remains in tombs alongside human remains confirm that even then, dogs were close to humans. Even today, the reasons and methods behind the domestication of dogs still need to be fully understood. Initially, dogs served as guards, later participated in hunting activities, and served as herding dogs. Shepherd dogs are employed in police forces to detect explosives and drugs, and also serve as guide dogs for visually impaired individuals. Dogs have also been utilised for scientific purposes, including specific medical and various other research endeavours. Today, there are numerous canine disciplines, including agility, flyball, frisbee, rescue dogs, mantrailing, rally obedience, nosework, lure coursing, and tricks. Within certain disciplines, specific dog breeds have proven to excel due to their favourable predispositions. For instance, in agility, breeds such as the border collie and shetland sheepdog stand out, among many others. In the field of nosework, the lagotto romagnolo has demonstrated exceptional aptitude. If a dog enjoys running alongside its owner, the sport discipline of canicross is available. Additionally, for those interested in awakening a dog's natural instincts, there is a field of utility dogs, encompassing three disciplines: obedience, tracking and protection. The rising number of disciplines has increased interest among individuals seeking companionship with their pets. Canine disciplines play a significant role in maintaining physical fitness, expending excess energy, and providing mental stimulation for dogs. Engaging in these activities also offers numerous advantages for humans, including increased physical activity, opportunities to be in nature, and the ability to spend quality time with their beloved dogs.
