Surgical debarking of dogs is illegal in three U.S. states outright — Massachusetts, New Jersey, and Maryland — and restricted in several others. Internationally, the procedure is banned or tightly limited across the United Kingdom, most of the European Union, New Zealand, parts of Australia, and several Canadian provinces. The common thread in these laws is that debarking (also called devocalization or ventriculocordectomy) is permitted only when a veterinarian certifies it is medically necessary for the animal’s own health.
U.S. States That Ban Debarking Outright
No federal law prohibits debarking in the United States. Three states have enacted full bans, each with a narrow medical-necessity exception.
Massachusetts
Massachusetts prohibits the surgical devocalization of any dog or cat. A licensed veterinarian may perform the procedure only after certifying in writing that it is medically necessary to treat an illness, disease, injury, or congenital abnormality causing the animal pain or harm, and the certification must be filed with the local town clerk. A violation can result in up to five years in state prison or two and a half years in a house of correction, a fine of up to $2,500, or both. Courts can also bar a convicted person from owning animals.1General Court of Massachusetts. Massachusetts General Laws Chapter 272, Section 80 1/2
New Jersey
New Jersey treats non-medical debarking as a crime of the third degree, carrying three to five years in prison and fines of up to $15,000. The procedure is lawful only when a licensed veterinarian determines it is necessary to protect the life or health of the dog. Any veterinarian who performs it must file a written statement with the Department of Health explaining the medical basis, along with the owner’s name and address.2Justia. New Jersey Revised Statutes Section 4-19-38 – Debarking Silencing of Dog, Certain Circumstances; Third Degree Crime
Maryland
Maryland makes surgical devocalization of a dog or cat a misdemeanor, again with a medical-necessity exception. A first offense carries up to 90 days in jail, a fine of up to $1,000, or both. A second or subsequent conviction raises the maximum to one year in prison and a $2,000 fine.3New York Codes, Rules and Regulations. Maryland Criminal Law 10-625 – Devocalization of Cats or Dogs
In all three states, the veterinarian who performs the procedure without proper medical justification faces the same criminal exposure as the dog’s owner.
States and Cities With Partial Restrictions
A handful of other U.S. jurisdictions restrict debarking without banning it. These fall into two groups: rules about how or by whom the surgery may be performed, and rules preventing landlords from demanding it.
Pennsylvania
Pennsylvania does not ban debarking, but it is a criminal offense for anyone other than a licensed veterinarian to perform the procedure, and the dog must be under anesthesia. Debarking a dog yourself, or hiring an unlicensed person to do it, falls under the state’s animal mutilation statute.4Pennsylvania General Assembly. 18 Pennsylvania Consolidated Statutes 5542 – Animal Mutilation and Related Offenses
Ohio
Ohio prohibits debarking a dog that is known or reasonably believed to be classified as dangerous, and it is also illegal to possess a dangerous dog that has been debarked. Before performing the procedure on any dog, a veterinarian may require the owner to sign a waiver attesting that the dog is not dangerous. A vet who obtains that signed waiver has an affirmative defense if charges are later brought. Debarking of non-dangerous dogs remains legal in the state.5Ohio Legislative Service Commission. Ohio Revised Code Section 955.22 – Confining, Restraining, Debarking Dogs
California and Rhode Island
California and Rhode Island do not ban the procedure itself. They prohibit property owners from demanding it. California’s Civil Code makes it illegal for a landlord, property manager, or anyone providing real-property-related services to require a tenant to devocalize an animal as a condition of occupancy, or to give preferential treatment to tenants whose animals have been debarked. Violations carry a civil penalty of up to $2,500.6LegInfo.Ca.Gov. AB 2743 Assembly Bill – Amended Rhode Island has a similar law barring property owners from requiring devocalization or declawing as a condition of occupancy.7State of Rhode Island General Assembly. Governor Signs Devocalization Bill
City Ordinances
Some cities have gone further than their states. Warwick and East Providence in Rhode Island adopted local ordinances banning devocalization outright, even though the state law reaches only the landlord side.7State of Rhode Island General Assembly. Governor Signs Devocalization Bill Other local jurisdictions may have their own restrictions, so checking your city or county code is worth doing if you live in a state without a statewide ban.
Penalties Where Debarking Is Banned
The three U.S. states with full bans take very different approaches to punishment:
- New Jersey: three to five years in prison and fines up to $15,000.2Justia. New Jersey Revised Statutes Section 4-19-38 – Debarking Silencing of Dog, Certain Circumstances; Third Degree Crime
- Massachusetts: up to five years in state prison or two and a half years in a house of correction, fines up to $2,500, and a possible ban on animal ownership.1General Court of Massachusetts. Massachusetts General Laws Chapter 272, Section 80 1/2
- Maryland: up to 90 days and a $1,000 fine for a first offense; up to one year and $2,000 for repeat offenses.3New York Codes, Rules and Regulations. Maryland Criminal Law 10-625 – Devocalization of Cats or Dogs
New Jersey’s exposure is the harshest in the country, placing illegal debarking on the same level as some assault and theft charges. Maryland’s is the lightest.
International Bans
Europe and the United Kingdom
The European Convention for the Protection of Pet Animals lists “devocalisation” as a prohibited surgical operation when performed for non-curative purposes. The Convention permits the procedure only when a veterinarian determines it is necessary for medical reasons or for the benefit of the animal itself.8United Nations Treaty Series. European Convention for the Protection of Pet Animals – Article 10 Signatories that have incorporated the Convention into domestic law effectively treat non-therapeutic debarking as illegal, including Austria, Belgium, Denmark, France, Germany, Italy, the Netherlands, Norway, Portugal, Sweden, Switzerland, and others.
The United Kingdom prohibits debarking under the Animal Welfare Act 2006, which makes it an offense to carry out a “prohibited procedure” on a protected animal. Debarking falls under the mutilation provisions because it is not among the permitted exceptions, grouping it with banned cosmetic surgeries like ear cropping and tail docking.9GOV.UK.

New Zealand and Australia
New Zealand restricts debarking under Section 17(2) of the Animal Welfare Act 1999, which allows the procedure only in the interests of the animal itself, not for owner convenience.10New Zealand Veterinary Association. Policy: Surgical Alteration to the Natural State of Animals Australia also bans the practice, though the specific legislation varies by state and territory rather than operating as a single national prohibition.
Canada
Canada has no federal prohibition, but Alberta, Nova Scotia, and Quebec all ban non-therapeutic debarking. British Columbia’s College of Veterinarians adopted a bylaw banning the practice, effectively making it unavailable in the province even without a statute.11BC SPCA. BC SPCA Calls for Ban on Dog Debarking These provincial bans align with the Canadian Veterinary Medical Association’s opposition to non-therapeutic devocalization.
Even Where Legal, Often Unavailable
In states without a ban, the law is only part of the picture. The American Veterinary Medical Association notes that debarking does not address the underlying reasons a dog barks, and that the procedure is “frequently ineffective” because it only reduces the volume and pitch rather than eliminating vocalization. The AVMA flags significant surgical risks and encourages behavioral solutions instead.12American Veterinary Medical Association. Canine Devocalization The American Animal Hospital Association goes further, stating it is “opposed to the practice known as debarking, canine devocalization, or vocal cordectomy,” with exceptions only in rare cases involving airway obstruction or laryngeal paralysis that cannot be addressed through other surgical options.13American Animal Hospital Association. Canine Devocalization
Many veterinary schools no longer teach the technique, and most practicing veterinarians decline to perform it. The practical result is that debarking is unavailable in large parts of the country where it remains technically legal.
