In the video, a dog is seen wearing a costume that makes it look like a spider. The costume includes a body suit and a headpiece with googly eyes. The dog is walking on a wooden floor in a hallway. The dog's movements are somewhat awkward as it tries to adjust to the costume. The costume is predominantly black and brown, with the googly eyes being white with black pupils. The dog appears to be a medium-sized breed with a white and black coat. The hallway is well-lit and there are no other objects or people visible in the video.
