A brain-teasing optical illusion is sweeping the internet, leaving thousands baffled and frustrated.

This viral image, shared in the well-known Reddit thread FindTheSniper, dares viewers to spot a cleverly hidden spaniel camouflaged among a dense web of tree branches.

At first glance, it appears to be nothing but a jumble of twigs and limbs—but don’t be deceived! A dog is tucked away somewhere in the picture. The real challenge? Finding it before it drives you crazy.

Reddit users are scratching their heads over the puzzle, with many admitting they still couldn’t spot the hidden dog even after receiving clues.

“I was convinced there was no dog in this picture. Had to double-check the original post to make sure I wasn’t being trolled,” one frustrated user admitted.

Another person gave up, saying, “I needed help with this one—way harder than I expected!”

So, what’s the secret to cracking this illusion? Experts recommend starting at the center of the image and slowly scanning outward. Still having trouble? Try shifting your focus slightly to the left—hidden among the branches, a brown spaniel is perfectly camouflaged.

This optical challenge is just one of many viral ‘sniper tests’ taking the internet by storm. From a snow leopard blending into rocky cliffs to puzzles that push depth perception to its limits, these brainteasers continue to captivate and confound people worldwide.
