In this amusing video, a cleverly designed 3D rug featuring a black-and-white vortex illusion is placed on the floor. As dogs approach, they hesitate, seemingly perplexed by the optical illusion that appears to create a hole in the ground. Their cautious reactions and attempts to navigate around the rug provide a delightful display of canine curiosity and confusion. The video highlights how visual tricks can playfully challenge our pets' perceptions.
