In the video, a baby is lying down in a stroller, and a dog is standing on its hind legs, shaking its head. The baby is wearing a white blanket and seems to be enjoying the interaction with the dog. The dog is a medium-sized, brown-furred animal with a long tail. The stroller is black and has a safety belt across the baby's chest. The floor is wooden, and there is a white wall in the background. The baby is smiling and laughing at the dog's antics.
