Everyone can see the cows – but you have 20/20 vision if you can spot the dog in under ten seconds

YOU might just have 20/20 vision if you can spot the dog amongst the cows in less than ten seconds.

The sneaky pup is hiding in plain sight but will leave you tearing your hair out as you try to find it.

This latest optical illusion is certainly not a walk in the park so be prepared to really put your skills to the test.

Only those with super sharp eyesight and strong identifying skills will be able to overcome this challenge.

But if you do find the dog - and in under ten seconds - then you must have 20/20 vision.

In the image, we can see at least 84 cows lined up in 14 rows of six.

The large amount of cows is already a difficult obstacle to overcome, meaning you're going to have to search twice as hard to find the odd one out.

And while you'd think a dog amongst cows would stick out like a sore thumb, this task is more likened to finding a needle in a haystack.

That's because we can only see the faces of each animal, making them harder to differentiate.

To make matters more difficult, these aren't just black and white spotted cows we're dealing with.

There are a number of different coloured animals, meaning this is an inexperienced puzzle player's nightmare.

But you don't have to necessarily be a master at puzzles to figure this one out.

You just have to be observant - and quick.

All of the cows have the same features, so it's down to you to figure out which one doesn't fit in.

If you managed to spot the dog, then congratulations.

And if you did so in under ten seconds or less, then you must have 20/20 vision and a high IQ.

If you are struggling, however, then here's what to do.

One of the main features on the cows is their horns, they all have them.

Besides the dog.

If you still can't find it, then perhaps this challenge isn't for you.

Should that be the case, then why not try one of our other entertaining optical illusion challenges.
