Evidence
Before you reach out about an animal welfare situation or other violation, you need to gather information and materials to support your report. A vague claim, an emotional appeal, or secondhand information will not get you far. In order for action to be taken, you must provide tools that the agency can use to help resolve the situation. They will need specific, detailed information and materials which can be used as evidence.

A Written Statement
Prepare a concise, factual statement of what you observed. Include dates and approximate times whenever possible, and describe the location with identifiers such as address, cross streets, landmarks, and whereabout of the animal(s) on the property. Your statement should clearly demonstrate that the situation is a violation of a specific law. It may be typed or handwritten.
Visual Representation
Take photographs of the location, the animal(s) in question, and the surrounding area — provided you can do so without putting yourself in danger and without committing any crimes. Videos are also helpful. Never enter another person’s property without permission, and exercise great caution around animals who may be frightened or in pain. Do not compromise your safety.
A List of Witnesses
Prepare a list of the names and contact information of others who have firsthand information and who are willing to speak to authorities if needed. They may be called to testify.
Veterinary Records
If you took the animal to a veterinary hospital or clinic for emergency treatment, have detailed records to show the treatment provided, the cost of that treatment, and any future treatment that may be required.
