I have personally witnessed Canadian Geese force a swimming dog further and further into a pond and attempt to drown it, hitting it in the face with their wings... I don't know if a dog has the advantage on land, but I have also witnessed a duck chase a dog for quite a long stretch in a large parking lot... Much funnier than the first scenario, but it is still proof that a dog is not necessarily the number one solution...
