Dog sports are activities that involve dogs. There is much discussion about what exactly defines a sport for dogs. Some issues:
If a human companion isn't actively involved, is it actually a sport? Take greyhound racing, for example, or hunting from, say, a duck blind, from which the dog retrieves the game.
Is any activity a sport? For example, a conformation show, where the handler and dog walk or trot around a ring for a judge to evaluate the dog's appearance and structure.
This list is intended only to represent anything that anyone is likely to refer to as a dog sport, not to argue its validity as sport. Clearly, there are more sports to add to this list:

Abandoned dogs who go feral are particularly dangerous; they lack the skills of wild canines at survival in the wild, as well as the genetic and learned fear of humans that keeps wild canines away from humans and their possessions, so they form predatory packs that attack livestock and occasionally also prove dangerous to humans.
Dogs with strong chase instincts may also fixate on specific stimuli, such as a fast-moving, brightly colored running or cycling shoe, as a prey object, and not recognize the whole picture as a human being; this is probably operative in the majority of cases of otherwise nonaggressive dogs chasing cyclists and runners.
Dogs possess a rete mirabile in the carotid sinus at the base of their neck, a complex of intermingled small arteries and veins which acts as a heat exchanger to thermally isolate the head, containing the brain, the most temperature sensitive organ, from the body, containing the muscles, where most of the heat is generated.
Canine Freestyle is a dogsport in which training, teamwork, music, and movement combine to create an artistic, choreographed performance highlighting the canine partner in a manner that celebrates the unique qualities of each individual dog.
In the realm of dogsports, Canine Freestyle is relatively new.
The Mission of the Musical DogSport Association is to advance the sport of Canine Freestyle and to share the joy of the canine/human bond achieved through positive training, enhanced by the artistry of music and choreography.
