In the video, a black dog with a pink collar is seen sniffing around a wooden fence. The dog is focused on a specific spot on the fence, moving its nose around the area. The fence appears to be made of weathered wood, and there is green foliage visible in the background. The dog's fur is shiny, and it seems to be a medium-sized breed. The pink collar stands out against the dog's black fur. The dog's behavior suggests that it may be trying to pick up a scent or investigate something on the fence.
