If you see a pet left outside in the cold or in a vehicle, speak up. The Humane Society of the United States suggests first politely letting the owner know you're concerned. If they don't respond well, document what you see: date, time, exact location and type of animal, plus as many details as possible. Video and photographic documentation will help. Then contact animal control, which here is the Humane Society of Carroll County (410-848-4810), or your local police agency. Take notes, then follow up in a few days if the situation hasn’t changed.
