A dog may think they're courageous until they find themselves stuck underneath a fence or on a tree branch. Ouch! And a pup may think he's going to conquer the world, only to come back down to earth and realize that's just not the case. Laugh away at the photos below!

This dog that thought he could swing.

And this bulldog that thought the slide looked fun.

This dog who only could make it halfway up.

This dog that went from a little cold to a little stuck.

This husky that hates trees.

This dog that wanted to see if the grass was really greener on your side.

This dog who never learned that hammocks are only for humans.

This dog who forgot about his crippling fear of heights.

This boxer who thought his legs were a little longer.

This dog that didn't measure twice.

This puppy that won't trust little girls anymore.

So next time your little guy wants to try to be the best pooch there is, remind him that he's not a cat with nine lives and that he needs to be careful. Otherwise, he'll be wishing he had made better life choices like the rest of these pups on Distractify!
