Connecticut Dangerous Dog Law

What happens right after a bite?

Connecticut handles a bite through the town's animal control officer (ACO), not a separate dangerous-dog board. The Department of Public Health says the victim or the dog's owner should report the bite to the local ACO¹³. The state Department of Agriculture's Animal Control Unit backs up municipal officers and enforces bite quarantines¹⁹.

The first order is almost always a quarantine. Since a 2019 amendment, § 22-359 requires the ACO to quarantine any dog that bites or attacks a person or another animal for 10 days (older guides still say 14)¹². On day 10 the State Veterinarian or a designee decides whether to lift it¹².

Can my dog stay home during quarantine?

• Vaccinated dog: home quarantine is allowed if your premises are adequate for confinement, as judged by the officer who issued the order¹².
• Unvaccinated dog: it goes to a public pound, a veterinary hospital or an approved commercial kennel. Home confinement is possible only if a veterinarian finds it medically necessary, the town accepts the premises, and the dog is vaccinated on day 10¹².

You pay for the quarantine, the exam, any vaccination and any rabies testing¹². Breaking a quarantine order brings a $250 fine, and the ACO can seize the dog and hold it at your expense until the quarantine ends¹². You may choose euthanasia for rabies testing during the quarantine, and a dog diagnosed as rabid is euthanized without notice¹².

Can animal control order restrictions or euthanasia?

Yes. Section 22-358(c), rewritten by Public Act 24-108 in 2024, lets the ACO make "any order concerning the restraint or disposal" of a biting or attacking dog once an investigation confirms that a person was in fact bitten or attacked¹¹. Connecticut does not sort dogs into "dangerous" and "potentially dangerous" tiers. The order is tailored to the case, and the officer must weigh at least seven factors¹¹:

1. your ability to control the dog;
2. how severe the injury was;
3. how vicious the bite or attack was;
4. any earlier bites or attacks;
5. whether it happened off your property;
6. whether the dog was provoked;
7. whether the dog was protecting you from physical harm.

A restraint order sets conditions on how the dog must be kept; a disposal order means euthanasia¹¹². A restraint order takes effect immediately and stays in force during an appeal¹¹. If the order is for disposal, the officer takes the dog and keeps it until the appeal is over¹¹. Police and military dogs under a handler's control, and service animals with their handler, are exempt if vaccinated and under routine veterinary care¹¹.

How do I appeal an order?

The timeline is short and runs from paperwork, not from the bite¹¹:

• Within 24 hours of the order, a copy must be delivered to you and to the person bitten, with a statement of your right to appeal.
• Within 15 days, the town must offer you, in writing, a pre-appeal meeting. You, your lawyer, the ACO, the officer's appointing authority and the victim may attend, and the parties can agree on a different order. Settlement talk there is confidential.
• The meeting must be concluded within 30 days of the order, and the town must issue a short statement of the outcome within 24 hours.
• You can then appeal to the Superior Court of the judicial district where you live, within 45 days of the order, or of the meeting statement if there was a meeting.

Before 2024, appeals went to the Commissioner of Agriculture, so older articles describe a hearing at the department; the statute in force in October 2026 sends them to court¹¹. Once an order is final it is enforceable anywhere in Connecticut¹¹.

What are the criminal penalties?

• Violating a final order is a class D misdemeanor: up to 30 days in jail, a $250 fine, or both¹¹².
• A nuisance dog kept despite a vicious disposition: an infraction the first time, a class D misdemeanor after that, and the court may order the dog restrained or disposed of¹⁷.
• A dog that habitually goes onto the highway and growls, bites or snaps at people: class D misdemeanor¹⁷.
• Roaming at large is an infraction. If you knew of the dog's vicious propensities, had already violated the leash law within the past year, and intentionally or recklessly let it roam again, and it injures someone who was not teasing it, the penalty rises to a fine of up to $1,000, six months in jail, or both¹⁸.
• Other violations of the dog chapter carry a fine of at least $250, up to 30 days, or both²¹.

Does Connecticut ban any breeds?

No. Since 2013 the municipal powers statute says that "no municipality shall adopt breed-specific dog ordinances"¹⁴. Orders under § 22-358 turn on the individual dog's conduct and the seven factors, not its breed¹¹.

What if the dog bites again?

A second incident starts a new investigation and usually a new quarantine. The officer must consider "any history of past bites or attacks", so a dog already under a restraint order is far more likely to face a disposal order¹¹. A prior roaming violation within a year also opens the door to the $1,000 criminal penalty if the dog injures someone¹⁸. The civil side is separate: the owner is strictly liable for each bite under § 22-357, whatever the outcome of the animal control case¹.

Rules for a declared dog in Connecticut

Connecticut rules in brief

Reporting. The Department of Public Health states that bites by domestic animals to people or other domestic animals are reportable to the local animal control officer by the victim or the animal's owner¹³. Anyone who kills an attacking dog in self-defense must also file a complaint with the town's animal control officer¹¹. Confirmed or suspected rabies must be reported to the State Veterinarian within 24 hours¹².

Euthanasia. An animal control officer who confirms a bite or attack may order the dog's restraint or disposal (euthanasia) to protect public health and safety¹¹. The officer keeps the dog during any appeal; the town must offer a pre-appeal meeting within 15 days, and the owner can appeal to the Superior Court within 45 days of the order or of the meeting statement¹¹. A court may also order disposal of a nuisance dog under § 22-363¹⁷.

Criminal penalties. Failing to comply with a final restraint or disposal order is a class D misdemeanor (up to 30 days and a $250 fine)¹¹². An owner who knew of the dog's vicious propensities and recklessly let it roam again within a year faces up to $1,000 and six months if it injures someone¹⁸. Chapter 435, the state's dog law, sets no felony for an attack that maims or kills; its general penalty for other violations is a fine of at least $250, up to 30 days in jail, or both²¹.

Breed rules. Since 2013, § 7-148 provides that "no municipality shall adopt breed-specific dog ordinances"¹⁴.
