A Doberman pinscher named Penny won best in show Tuesday night at the Westminster Kennel Club Dog Show, netting U.S. show dogs' most coveted prize. Penny bested six other finalists at New York's Madison Square Garden. Each dog is judged according to how closely it matches the ideal for its breed.

The disturbing video of a U.S. marshal kicking a small dog went viral on social media and has raised questions and concerns from the dog's owner.
