In the video, a man is seen brushing a dog's teeth with a toothbrush. The man is holding the toothbrush in his right hand and the toothpaste in his left hand. He is carefully applying the toothpaste onto the brush and then brushing the dog's teeth. The dog seems to be cooperative and is sitting calmly while the man is doing this. The man is wearing a green shirt and the dog is white in color. The background is not clearly visible, but it seems to be an outdoor setting.
