Are you eagle-eyed? On the social media site Reddit, a woman decided to challenge fellow users.
She shared a photo of her two dogs playing in her garden. The only problem is, you can only see one of them in the snap. So, where is the other one?

A tricky challenge
In the caption for her post, she asked: "Can you find the second dog?". Users immediately began searching for the hidden pooch.
While some struggled to spot him at first glance, many others managed to locate him.
Now it's your turn
What about you, have you found him yet? Give it a go.
