What We Do & Services

Animal Control Investigations

Animal Care Services Field Operations Division is responsible for protecting the health and safety of the citizens and their pets in the City of San Antonio. In addition to responding to standard call-for-service requests, ACS has specialized investigative teams responsible for cases involving animal bites, dangerous or aggressive dogs, animal cruelty, and permitting concerns.


Bite Investigations

State law mandates all animal bites or scratches that break skin must be reported to the local rabies control authority. Animal Care Services is the local rabies control authority for the City of San Antonio and all rabies exposures must be reported immediately.

If you are a citizen who has been bitten, please call 3-1-1 to report the bite immediately. If you are a representative of a veterinary clinic or medical facility who is reporting a bite, please email ACS Bite Investigation Team to obtain a copy of the Animal Bite Exposure Form. Find additional information regarding Animal Bite Investigations (.pdf).

Dangerous/Aggressive Dog Investigations

Animal Care Services takes the health and safety of both citizens and pets very seriously.  San Antonio’s dangerous and aggressive dog laws are taken directly from State law. Their mission is to prevent future dog bites or attacks from happening by requiring safeguards that protect people from a specific dog who has been involved in a documented, unprovoked incident.

ACS cannot self-initiate a dangerous dog investigation. Only a witness or victim may initiate an investigation by filling out a sworn (notarized) affidavit detailing the facts of the incident. Please Note: Animal Care Services provides notary service free of charge for ACS-related cases anytime during regular business hours. For your convenience, Animal Care Services is open seven days a week: Monday through Friday 11 a.m. to 7 p.m. and weekends 11 a.m. to 5 p.m.  

Following the receipt of the legal document (affidavit linked above), Animal Care Services will begin a comprehensive investigation of the incident to determine if there has indeed been a violation of the existing law. The owners of animals who have been found in violation of this ordinance can be held liable both civilly and criminally. For more information on the community’s dangerous and aggressive dog laws, please visit the City’s Chapter 5 Animal Ordinances.
