Pitch invaders are the curse of sport around the globe, but when it comes to those from the animal world athletes, fans and security are, fortunately, a touch more forgiving.
Such was the case in Argentina on the weekend when a dog loped onto the field during a first-division match between Belgrano and Quilmes, only to be lovingly scooped up by a player and carried to the sideline.
Golfers also get their fair share of animal interaction with pheasants, seagulls and even alligators.
Check out the menagerie of pitch and course invaders.
