Dallas Animal Services

Dangerous & Aggressive Dogs



Dallas Animal Services encourages responsible pet ownership through continued education and outreach efforts. If a dog has been deemed dangerous in the City of Dallas, the owner must comply with specific requirements to ensure that people feel safe where they live, work, and play. Dangerous and aggressive dog determinations are governed by both state law (Section 822.041-.047 of the Texas Health and Safety Code) and local ordinances.

What is the Difference? 

An aggressive dog means a dog that on at least one occasion, while not legally restrained, killed or injured a legally restrained domestic animal or livestock.

A dangerous dog is a dog that makes an unprovoked attack (or unprovoked actions that suggest the dog will cause serious bodily injury in the future) that causes injury to a human.
