You have high IQ and 'sniper vision' if you can spot hidden dog stood in the snow in this image

If you're sniping is any good on CoD then you might want to test it out in the real underground world of Reddit.

One user has taken to the r/FindTheSniper feed to share an optical illusion of a winter wonderland.

More specifically, there is a white dog pictured in and amongst snow-covered trees in a forest, and the Reddit user has challenged people to see if they can spot it.

With heavy snowfall on first glance, it looks almost impossible to find the white-coloured dog, camouflaged against the white backdrop.

And to make things harder, the user has challenged people to locate the pooch within 20 seconds or under.

If you're feeling up for it, take a look below:

Struggling? Well here's one hint for you.

Although the dog's white fur is blended in with the snow, its ears, nose and eyes are what you need to be looking out for.

If you're still having a bit of trouble, take a peak at the centre of the photo.

Yep, you can see its little ears perking up as it's frolicking through the forest.

Now, if that was too easy for you, here's a slightly more challenging one.

In the same 'FindTheSniper' thread, another user has shared an image of a snake camouflaged in the woods.

"Find the copperhead," reads the caption, as the user explains: "Tossed this little guy out into the woods after I stumbled on him during some landscaping at the house.

"PSA: don't kill copperheads, they're just vibing. Politely relocate them; they appreciate not being turned into 'snake bites.'"

Go on then, let's see if you can find it:

This one is a bit more challenging. (Reddit)

A copperhead is a small venomous snake found in North America, it's especially prominent in wooded areas.

It's got a bit of a killer look to it with reddish-brown, round-shaped patterns running down its back.

Many were struggling to find the ol' snake, with one person commenting: "Oh! There it– nope. Oh! It's th– nope. Honestly it's crazy how effective camouflage is."

Meanwhile, an experienced 'snake sniper' was able to locate the animal, revealing that the copperhead is in the 'bottom left-hand corner'.

"But you gotta keep your eyes sharp! He’s almost completely hidden!" they explained.

Users also noted that you do need to zoom in to the photo to see it, writing: "Thank you ZOOM, if it wasn't for you, I wouldn't have been able to spot the snake. My actual eyes; take note."
