Winston checked a massive 18 month old English Mastiff and corrected his bad manners. This was the first time the English Mastiff came to the dog park and he was unsure of himself. He showed a little aggression but I think he was just scared of the other dogs and did not know what to do. If you look closely you can see how he widens his eyes when he gets spooked by the other dogs.

There is no violence in this video. This video exists in order to educate people about dogs and dog behavior at dog parks.
