Knowing that dogs love to fetch things, this tournament in Brazil decided to hire some adorable street dogs as its 'ball boys' for the tennis matches.

These dogs, who were rescued from the slums of Brazil, were specially trained to do amazing tricks like this one. Their performance was almost perfect because they are quick on fetching the tennis balls as soon as it falls on the floor. However, they have this hilarious hobby of not returning the ball to the players.

Even though this was the case, there is no denying that they are all adorable in doing their jobs.

Watch the funny video below.
