The Unique Dog

The Unique Dog is one tricky challenge that you must play. Start the adventure right now and see how far can you get. In each level, you will get many dogs and each one of them has a pair. Each one, except for one. Your job is to find that unique dog and thus complete the level. Be fast and finish your research within the given time limit or you will lose all your progress. One more way to fail is to click several times on dogs that already have a pair. Good luck and have fun with The Unique Dog!
