Who Pays When a Dog Bites Another Dog?

Another dog went after yours. Now your dog is hurt, the vet bills are adding up, and you’re wondering whether the other owner has to pay. If you’re still shaken and unsure what you can even ask for, that’s a normal place to be.

Here’s the plain answer. Usually the attacking dog’s owner pays, often through their homeowners or renters insurance, if the owner is legally responsible. In Michigan, that generally means showing the owner was at fault, because the dog-bite statute applies only when “a dog bites a person” (MCL 287.351(1)). And because Michigan treats pets as property, the claim is for money losses, not for your fear or grief (Koester v VCA Animal Hospital, 2000).

The hard part is usually the claims process: proving fault to an insurer that handles claims like this routinely. Unless another state is named, the rules below are Michigan’s, current as of September 2026.

Who is responsible when a dog attacks another dog?

Usually the owner of the dog that attacked. Someone who was only watching the dog can be responsible too, if they were careless (Trager v Thor, 1994).

Some states’ dog laws cover attacks on animals: Connecticut’s covers damage to “the body or property of any person,” including a companion animal (Conn. Gen. Stat. § 22-357), and Florida’s covers damage to domestic animals, dogs included (Fla. Stat. §§ 767.01, 585.01). See the state-by-state table.

What should you do right after a dog attacks your dog?

1. Separate the dogs safely. Keep your hands away from their heads: a dog in a fight may bite whoever is close, even its owner. A veterinary emergency specialist suggests water from a hose or bucket, an air horn, or a barrier such as a door or plywood, and warns against kicking either dog (Veterinary Information Network).
2. Call your vet now, even if the wounds look small: punctures from canine teeth can close over quickly and be missed (VCA Animal Hospitals).
3. Ask for the other dog’s rabies record for your vet. Michigan requires owners to keep dogs 4 months and older vaccinated against rabies (MCL 287.266(1), (8)).
4. Get names and numbers from the other owner and any witnesses, plus the owner’s home insurer, and report the attack to animal control or the police.
5. Keep evidence: photos of the wounds and the scene, any doorbell video, every receipt, and proof of what your dog was worth.

What can you recover for your dog’s injuries?

Pets “have long been considered personal property in Michigan jurisprudence” (Koester), so a claim for your dog is valued in money, like other property damage.

• The general rule. For property damaged through negligence, it’s the cost of repairs if that’s less than the property is worth, or the drop in market value if the damage is permanent (Price v High Pointe Oil Co, 2013, quoting a 1934 decision).
• For animals. Michigan courts have measured an injured animal’s damages by the drop in its market value, and a killed animal’s by its value (Davidson v Michigan Central R Co, 1882; Guzowski v Detroit Racing Ass’n, 1983, a racehorse).
• Not your grief. The Court of Appeals refused damages for emotional distress and lost companionship when a dog died after allegedly negligent veterinary care (Koester). The Michigan Supreme Court later held that noneconomic damages can’t be recovered for negligently damaged or destroyed property, seeing no legal basis for treating a pet differently from a house (Price).

How vet bills fit isn’t settled. Davidson, a horse case, said the cost of treatment “could not usually be a very reasonable claim,” and we found no published Michigan appellate decision on a pet’s vet bills, including bills above its market value. Keep every bill and your proof of the dog’s value.

How do you show the other owner was at fault?

A fight alone doesn’t prove the other owner did anything wrong. Michigan’s Supreme Court has said dogs are generally regarded as so unlikely to do substantial harm that owners have no duty to keep them under constant control. A negligence claim arises from “ineffective control of an animal in a situation where it would reasonably be expected that injury could occur,” and the control required depends on “the total situation at the time, including the past behavior of the animal and the injuries that could have been reasonably foreseen” (Trager). What helps:

• A loose dog. A statute can require more, such as the Dog Law’s leash rule (Trager): an owner may not let a dog “stray unless held properly in leash,” except working dogs, such as hunting dogs, on the job with their owner or the owner’s agent (MCL 287.262). Breaking a statute can let a jury infer negligence, and breaking a local ordinance is evidence of negligence for the jury to weigh with the rest, if the law was meant to protect against this kind of harm and people in your position (M Civ JI 12.01, 12.03; Rickrode v Wistinghausen, 1983).
• What the owner knew. Earlier attacks, complaints or warnings. An owner who knows of a dangerous tendency must control the dog enough to guard against it, and one who knew or had reason to know of an abnormally dangerous tendency can be liable for the harm it causes even after taking “the utmost care” (Trager).

If you were partly at fault, say your dog was off its leash too, Michigan reduces a property-damage award by your percentage of fault (MCL 600.2959). See how comparative fault works in Michigan.

Will the other owner’s insurance pay?

Often, if the owner is legally responsible. Homeowners liability coverage “provides protection in the event you become legally obligated to pay for bodily injury or property damage,” including a defense, and renters policies include liability coverage too (Michigan Department of Insurance and Financial Services, or DIFS). Your dog is property, and a standard homeowners form defines property damage as “physical injury to, destruction of, or loss of use of tangible property” (Insurance Services Office sample policy). Some policies also cover damage the policyholder causes to other people’s property (DIFS), so ask about that too.

Before any call with an insurer, read what to say, and not say, to an insurance adjuster.

Can you take the other owner to small claims court?

Yes, if your losses are within your state’s limit, which varies by state.

Can you have the other dog declared dangerous?

In Michigan, possibly, but it’s a separate court case about the dog, not a way to get paid.

What if you were bitten breaking up the fight?

If the other dog bit you, you may have your own injury claim. Get the bite treated, and see what to do in the first hours after a dog bite.

How long do you have to make a claim?

Every state sets a deadline; see injury deadlines in every state. In Michigan, it’s generally 3 years from the injury, for your dog’s claim and your own: the rule covers “injury to a person or property” (MCL 600.5805(2)). Negotiating with an insurer isn’t on the list of things that pause the clock (MCL 600.5856).

What to do next

1. Get your dog treated, and yourself if you were bitten, and keep every record.
2. Identify the other owner and their insurer, and report the attack.
3. Build your proof: photos, video, witnesses, a leash-law violation, any history of attacks.
4. Make your claim in writing. If it’s refused and it’s $7,000 or less, Michigan’s small claims court is an option.
5. If you were bitten or the losses are large, get a free case review well before the 3-year deadline, or in Michigan, compare injury lawyers near you.

What waiting can cost

• Your dog’s recovery. Bite wounds treated within six hours have the best chance of healing without complications (VCA Animal Hospitals).
• Evidence. Wounds heal, video gets recorded over and witnesses forget.
• Your right to sue. In Michigan, generally 3 years from the attack (MCL 600.5805(2)).

What a good outcome looks like

Your dog is treated and recovering, the attack is on record, and the other owner or their insurer pays what the law allows. If you were bitten, your own claim moves on its own track, well inside the deadline. From staring at a vet bill and wondering whether anyone else has to pay it to knowing who’s responsible, what you can claim and how to collect.
