The challenge is to discover the dog in a herd of cows in less than 30 seconds. It sounds easy, but this puzzle is not as easy as it appears. In fact, only one percent of people can discover the dog within the time limit, making this one of the most difficult optical illusions ever. The photo contains a herd of cows with many colors and postures so that it creates a fairly complex and unknown effect. Somewhere in all the cows, there must be an invisible but not described dog. This illusion checks your focus and deep vision. The color and pattern of cattle are so diverse that you may not even notice how the dog can blend into the surrounding environment. When you continue to stare at the picture, you will start crazy and start thinking that the dog really exists and has your hiding places. It is here that the magic of optical illusion appears to challenge you to look further than the surface level and attract your brain in a new way. So do you like challenges? Discover the dog within 30 seconds. Most of the audience spent a long time staring at the picture even to find the hidden animal. But there is no need to worry, because we are here to give you an easy escape. When observing closely, you can see that the dog has blended very well with the cows so that it can hide behind the models of the guitar. If you haven’t found it, take a deep breath, focus and go a puzzle. That is the process, not the final result.
