Hi ya, VK!
The swamp can try to fight back, but they will lose. The owner of the dog's last name is McCoy. In the English language we signify that to mean the real deal or genuine.

Here is a quote from an article on him~

Despite the danger, McCoy said he had no doubts about rescuing his dog.

"No hesitation," he told ABC Action News. "It’s just the way it is."
