Bounding out onto the pitch about 52 minutes into the game, the dogs played tug-of-war and looked for some attention from the players in the video clip.
The whistle was blown and the players stopped as soon as the dogs set foot -- or paw -- on the field. With play halted, officials attempted to catch the Labs and carry them off the field.
After the adorable interruption, VfR Aalen went on to win the friendly match, 1-0.
In 2011, an unrestrained police dog rushed the field during a match between Ituiutaba and Uberlandia and attempted to steal the ball.
Watch as the two Labs run amuck on the field in the video above and see more on-field animal incidents in the gallery below.
