It can be heartbreaking to witness animal abuse, such as a dog living outside in frigid conditions, or a malnourished horse. To help the animal, it's important to snap photos so the agency you report to has evidence. Then call and report the abuse to the local authorities, including the police department, animal control agency or animal shelter in your community. Do not confront the person who is neglecting the animal. And if you wish to remain anonymous, you can: Almost every jurisdiction allows witnesses to report without sharing a name or contact information.
