To report a dog attack on another dog, call your local animal control agency’s non-emergency line as soon as your own dog is safe and has been seen by a veterinarian. Animal control is the agency with authority to investigate the incident, cite the other owner, and pursue a dangerous dog designation if the facts warrant it. The report you file also becomes the official record you’ll rely on later if you go after the other owner for your vet bills. What follows is how to make that report count.
Get Your Dog to a Vet Before You File
Separate the dogs without putting your hands near either dog’s head, then move your dog out of the area immediately. Even a brief pause can restart the fight.
Get to a veterinarian within hours, even if your dog looks fine. Puncture wounds are deceptive: the skin closes over quickly while the tissue underneath is badly damaged and already breeding infection. The vet visit does two things at once. It gives your dog the best chance of avoiding complications, and it creates a dated medical record tying the injuries directly to the attack. That record is the single strongest piece of evidence you’ll hand to animal control and, later, to a judge or insurance adjuster.
Check yourself for bites too. An injured or panicked dog may bite anyone nearby, including its own owner.
Document the Scene Before You Call
Officers investigate dozens of complaints. The reports that get taken seriously are the ones that arrive with organized evidence attached.
Write down the exact date, time, and location while your memory is fresh, and put the events in order. Get a physical description of the attacking dog: breed or best guess, size, color, collar, tags, any distinguishing marks. If the other owner is there, get their name, address, and phone number. If they refuse or leave, note what they look like and the direction they went.
Ask anyone who saw what happened for their name and contact information. A witness willing to confirm your account carries real weight in an investigation where the other owner will likely tell a different story.
Use your phone. Photograph your dog’s injuries from multiple angles, the location, and the attacking dog if it’s still there. Look around for security cameras on nearby homes or businesses and note their locations for the officer. Save every piece of vet paperwork: the exam report, treatment notes, prescriptions, and itemized bills. Keep originals; hand over copies.
Who to Call
Animal Control
Your local animal control agency is the primary authority for dog-on-dog attacks. These officers enforce leash laws, investigate bite incidents, issue citations, quarantine animals, and initiate dangerous dog proceedings. In most jurisdictions, animal control is the only agency that can formally investigate and take action against the attacking dog and its owner.
Police
Call the police in specific situations: the other owner was threatening or aggressive toward you, they left the scene without giving you their information, or the attack happened outside animal control’s business hours. Officers can document the incident on the spot and forward the report to animal control for follow-up. A police report also strengthens your position if you later pursue a civil claim.
Local Health Department
Contact the health department if the attacking dog’s vaccination status is unknown or the animal appeared sick or was behaving strangely. Health departments manage rabies risk. The CDC recommends that a healthy dog suspected of rabies exposure be confined and observed for 10 days after the incident, and the health department can coordinate that quarantine.1Centers for Disease Control and Prevention.

Making the Call
Use the non-emergency line. Tell the dispatcher you’re reporting a dog attack on your animal and give them the basics: where and when, a brief summary, and whether you know the other dog’s owner. Provide your own name, address, and phone number. Before you hang up, ask for a case or report number. That number is how you’ll track everything from here on.
An officer will follow up in person or by phone. Walk through the events in order, stick to the facts, and hand over copies of your photos, veterinary records, and witness contact information. Some agencies accept email; others use online portals or want physical copies dropped off. Ask which the officer prefers, and keep your originals in every case.
If you couldn’t identify the other owner at the scene, tell the officer about any security cameras you noticed. Animal control may also have prior complaints on file involving the same dog, which can help them track down the owner.
What Animal Control Does With Your Report
The agency opens an investigation. The officer contacts the other owner for their version, verifies the dog’s license and vaccination records, and interviews the witnesses you identified. How long this takes varies with the agency’s caseload and the owner’s cooperation.
The outcome depends on the severity of the attack and the dog’s history. For a first offense with minor injuries, the owner might get a warning or a citation for violating a local ordinance such as a leash law. Citations carry fines, and the owner will be ordered to keep the dog properly contained.
More serious attacks or repeat offenders trigger stronger consequences. If the attacking dog’s rabies vaccination can’t be confirmed, animal control will impose a mandatory quarantine, typically 10 days, at the owner’s home or at an animal control facility.1Centers for Disease Control and Prevention. Information for Veterinarians – Rabies The agency may also initiate a formal hearing to declare the dog “potentially dangerous” or “vicious.” That designation carries real weight: the owner may be required to muzzle the dog in public, build a specific type of enclosure, carry liability insurance, or rehome the dog to another jurisdiction. In the most extreme cases involving severe injury or a documented history of attacks, euthanasia is on the table.
You may be asked to give testimony or a written statement at a dangerous dog hearing. Treat it like a court proceeding. Bring your documentation, present the facts clearly, and stick to what you personally witnessed.
Using the Report to Recover Your Vet Bills
Filing the report handles public safety and creates the record. Getting your bills paid is a separate process, and it won’t happen automatically.
Start with a written demand to the other owner. Include a summary of the incident, copies of your veterinary bills, and a specific dollar amount. Send it by certified mail with return receipt and give the owner roughly 30 days to respond. Many disputes resolve here because the owner would rather pay than face a formal process.
If the owner has homeowners or renters insurance, that policy likely covers liability for damage their dog causes, including attacks on other dogs. Ask for the insurer’s name and policy number, then file a third-party liability claim directly with the company. An adjuster will investigate and either offer a settlement or deny the claim.
If neither route works, small claims court is built for this kind of dispute. Filing fees are generally modest and you won’t need a lawyer. Bring your animal control report, veterinary records, photographs, witness statements, and a copy of your demand letter with the certified mail receipt.
Whether the other owner is on the hook depends on your state’s law. Roughly 36 states have some form of strict liability, meaning the owner is responsible for damage their dog causes regardless of whether they knew the dog was aggressive, and many of these statutes explicitly cover damage to other people’s domestic animals. The remaining states apply a version of the “one-bite rule”: the owner is liable only if they knew or should have known the dog had dangerous tendencies. In a one-bite state, prior complaints in animal control’s file are how you show the owner was on notice, which is another reason the report you filed matters well beyond the initial investigation.
Dogs are classified as personal property in every state, which shapes what you can recover. Veterinary bills are the baseline. Some states also allow recovery of the dog’s fair market value if the attack was fatal, and a smaller number permit additional amounts such as burial costs. Emotional distress damages for harm to a pet remain rare but not unheard of in certain jurisdictions.
