YouTube vlogger Trevor Costelloe and his friend were out exploring an abandoned water park and began filming it when something very unexpected happened.

At first, they noticed a big white dog looking at them from a distance. The boys were leery to get closer, since they didn’t know if he was friendly or not.

But after a few seconds they decided to walk closer to him. They then noticed a second dog who was also staring at them.

Both of the dogs came running toward them, wagging their tails and jumping up on them. Then they ran toward where they came from, looking back at the boys as if they were leading them.

When the boys looked toward where the pups were leading them, they noticed splashing in the water. As they got closer, they realized it was a dog who was drowning.

Although the water park is abandoned, it had rained the night before, so some parts of the park got filled with water. This dog somehow slipped in and was unable to get out on his own.

It was then apparent to the boys that these two pups were trying to get their attention so that they could help save their friend.

Costelloe quickly went toward the drowning dog and leaned in until he could grab ahold of him. The dog was struggling to stay afloat and was growing more tired by the second. Costelloe pulled the poor pup out of the water and onto dry land.

His two doggy friends ran right up to him, licking him and wagging their tails. They were so grateful that their friend was now safe!

If it weren’t for Costelloe and his friend being there that day, the dog would have drowned. They were just at the right place at the right time, and it’s amazing that they just happened to catch the whole thing on camera too!
