Brazilian fans were treated to this epic display of agility and elusiveness after a dog halted a football match between Grêmio Esportivo Brasil and visiting Goiás Esporte Clube.
The dog took a particular interest in Goias defender Evanildo Borges Barbosa Junior, better known a Juninho in front of thousands of fans before chasing him around and trying to jump on him.
The match was stopped for few minutes as stewards and players attempted to get the dog off the player.
Eventually it was carried off the pitch, allowing the game to continue as before.
Dogs are aggressive in response to unfolding events. Any dog has the ability to use aggression, but rarely do players run into a problem like this which are hard to explain, so maybe let's say "the dog is mad."
