Westchester
Protection Dogs

The county’s own website describes Westchester as six cities, 19 towns, and 20 villages. We looked for a county-wide ordinance on guard or attack dogs and did not find one among the county’s pages. What the county does publish about dogs is a parks policy, a registry of dogs a judge has found dangerous and a health department that handles bite investigations. The rules about a dog trained to attack or protect sit in municipal codes, and they are where this page spends its time.

State law lies underneath every one of those codes: the civil-liability rule, the dangerous-dog hearing and how a clerk licenses a dog. It is on our New York page and none of it is restated here. What follows is the local layer a Westchester buyer meets after reading that page.

We read the codes of seven municipalities and five county pages on 14 October 2026, and quote the wording that matters. We did not read the county’s other codes, so a place that is missing here tells you nothing about its rules. We are dog trainers, not lawyers or insurers. This page is not legal or insurance advice, and how any code applies to a particular dog is a question for the municipal clerk, the town or village attorney or a New York lawyer.

Our reading, and only that: a code phrased around what a dog was trained to do is aimed at the dog’s history, not only at what it has done. Whether bite work on a decoy counts as being “trained to attack” in any of these phrases is a legal question, and the clerk or the municipal attorney answers it. We do not, and we do not say here that a dog from us would or would not be caught. How we think about the words guard and protection is set out in our guard dog guide.

A household buying a puppy through Build Your Own Pup should ask the same question as one buying a fully trained dog. None of the codes quoted here says at what stage of training its wording begins to apply, so put the question to the clerk before the dog arrives, not when it is grown.

Article V of the city’s animal chapter is titled “Guard or Attack Dogs.” Section 89-14 defines a guard dog as “a dog trained to attack any person or creature coming upon the premises containing such guard dog” and an attack dog as “a dog trained to attack upon command.” Nobody may keep or harbor either one “unless such person shall first register with the City Clerk.” The registration gives the Clerk a description of the dog, the address where it will live and the owner’s name, and the premises must carry, in a conspicuous place, a sign “not less than 12 inches by 12 inches in size” reading “Beware, Dangerous Dog on Premises.” The penalty in § 89-15 is a fine of up to $250, up to 15 days’ imprisonment, or both.

Two things follow from the text, in our reading. The order of the sentence puts registration before keeping, and the section names no grace period for a dog that has just arrived, so when and how a new owner registers is a question for the Clerk before the handover. And the sign says “Dangerous Dog” whatever the dog’s temperament, which a household that wants no sign on its gate should weigh. Whether a given dog falls under either definition is for the City Clerk or the city’s lawyers to answer, not us and not a seller.

Pound Ridge words its rule around purpose rather than technique. Section 39-7 applies to “owners or persons harboring dogs which are trained for the purpose of protecting persons and/or property,” and requires “easily visible signs at each and every vehicular and/or pedestrian access to their property, warning visitors to beware of guard dogs on the site.” The word attack does not appear in it. The trigger is what the dog is trained to protect, and the duty is a warning at every way in.

“Each and every” is a count taken on the ground. On our reading, a property with a front drive, a walk-in gate and a back lane has three to sign, and the section does not say how an access shared with a neighbor is counted. For scale, the Census Bureau puts the town at 22.31 square miles and 227.8 people per square mile in 2020, a small fraction of Scarsdale’s 2,734.5.

The fine schedule in § 39-11 sets $200 for a first violation of § 39-7 and $400 for a second or later within six months; for habitual offenders with three or more convictions it allows up to $800. Two further rules reach a working household directly. Section 39-12.1 says a household, “whether owners or tenants,” may not keep more than four dogs over the age of five months. And under § 39-5 a dog off its owner’s premises must be “demonstrably under control of its owner or a responsible person” and leashed at public events, in the Town Park unless the Recreation Commission directs otherwise, in the Scotts Corners business district and on the bike path between them. The same section bars a dog that bites or harasses a person “peaceably conducting himself or herself” where they may lawfully be, and says this does not preclude action by the Town Justice Court under the state dangerous-dog law covered on our New York page.

Of the codes we read, Mount Kisco’s is the one a buyer should read twice. Section 55-1 defines a vicious dog in two limbs. The first is “Any dog owned, harbored or trained primarily or in part for the purpose of dogfighting.” The second is “Any dog owned, harbored or trained primarily or in part for the purpose of attacking a human being or domestic animal upon command.” Section 55-5 then says “No person shall permit, keep, maintain or allow any vicious dog in any building or on any property within the Village of Mount Kisco,” and goes on: “nor breed, attempt to breed, buy or attempt to buy any vicious dog.” As written, the prohibition reaches buying, not only keeping.

The exceptions in § 55-8 are the Village itself, a police officer “acting within the scope of his official duties,” and a licensed veterinarian keeping an animal on the business premises for treatment or humane euthanasia. A private household is not on the list. Section 55-7 sends a violation to § 1-17B of the general penalties, which for an individual provides a fine of not more than $500 and not less than $250, imprisonment for not more than 15 days, or both; § 1-17D treats each day a violation continues as a separate offense.

Do not confuse the vicious-dog definition with the village’s separate “dangerous dog” definition. The carve-out for injury caused “in protecting or defending a human being within the immediate vicinity of the dog from an unjustified attack or assault” sits in the dangerous-dog definition, and we found no matching carve-out in the vicious-dog limbs quoted above. The dangerous-dog rule in § 55-4 has its own demands: a dangerous dog off its property or unconfined on it must be muzzled and on a chain of at most three feet, and the owner must post notices on the property’s perimeter. Separately, § 55-3 requires every dog in a public place to be on a leash “not exceeding six feet in length.”

Whether a dog trained in bite work is trained “for the purpose of attacking a human being … upon command” is the question this section turns on, and we will not answer it for anyone. Put it to the Village Clerk or the Village Attorney and get the answer in writing before any handover, because a prohibition on buying is a bad thing to discover after the money has moved.

Peekskill’s dangerous-dog article defines a dangerous dog to include any dog “Owned, harbored or trained primarily or in part for the purpose of attacking a human being or domestic animal upon command” (§ 250-9), the Mount Kisco phrase again, with a different result. A City Court judge decides after a hearing held “no less than five days nor more than 15 days after such notice is mailed to the owner.” Section 250-13 separately bars anyone from training or using a dog “for the purpose of causing or encouraging the dog to attack human beings or domestic animals when not provoked.” A violation of the article is, under § 250-15, “a misdemeanor punishable by a fine of not less than $500 nor more than $5,000,” with imprisonment of up to a year available as well.

Bedford’s Article III presumes a dog dangerous if it “has been trained, tormented, badgered, baited or encouraged to engage in unprovoked attack upon persons or domestic animals,” and says the dog “is hereby presumed to be a dangerous dog for the purposes of this section, until further determination of facts are made.” Two details are worth noticing. The word in the text is unprovoked, and what counts as provocation for a dog trained on a decoy is a question for a lawyer, not for us. And the definition’s one exclusion is for “a police work dog,” which the section limits to a dog owned or harbored by a police department or law enforcement agency and actually used for police work.

The complaint, the seizure on probable cause and the hearing within five days follow the state process on our New York page. What Bedford adds is below.

Section 48-28(E) lifts the owner’s liability under the bite and death penalties in § 48-28 where the dog was “coming to the aid or defense of a person” during one of a list of serious crimes, in wording close to the state exception discussed on our New York page, including the words “within the dwelling or upon the real property of the owner of the dog.” How far that phrase reaches is the same open question, and a lawyer answers it.

Day-to-day rules sit in Article I. A dog may not be in any public park, or in the business zones of Bedford Village, Bedford Hills and Katonah, “unless the dog is restrained by a leash or is within a motor vehicle,” with the Canine Tribute Park excepted. Off its owner’s premises a dog must be “under the visual, voice or sound control of its owner or a responsible person able to control the dog.” And an owner of a dog already found dangerous must show a policy of at least $100,000 when licensing or renewing.

Neither the Scarsdale village chapters nor the Rye city chapter we read says anything about training. They matter to a working-breed household for another reason: how they handle the yard and the street. Scarsdale is 6.68 square miles with 2,734.5 people per square mile and 92.3% owner-occupied housing, and Rye is 5.85 square miles with 2,834.8 per square mile and 70.4% owner-occupied.

The Scarsdale penalties are modest on paper: up to $25 for a first violation of the leash and park section, up to $100 for a first violation of the vicious-animal section and up to $250 or 15 days on a second. We do not read that as a reason to ignore them. A fence is a long-term purchase, and a height cap is cheaper to learn before the dog arrives than after the posts are set. Whether one particular dog is held by a four-foot fence is a question about that dog and that lot, and worth raising with any seller before you buy.

The county parks’ dog policy says “Dogs are allowed in most parks, but they must be leashed; leash not to exceed 6 feet in length.” It adds “Limit of 3 dogs per person.” It bars dogs from county nature preserves and sanctuaries, Lasdon Park and Arboretum, Muscoot Farm, Playland Amusement Park, the Sportsman Center and Washington’s Headquarters, and adds “Dogs are not permitted in picnic areas or playgrounds.” One sentence matters to anyone planning to work a dog: “Dog walking/training services are prohibited on parks property.” The page does not define “training services,” so ask the Parks Department before doing any obedience work there.

The Department of Health keeps a dangerous-dog registry of dogs in the county “classified as ‘dangerous’ under New York State Law.” It lists a dog’s residence, description and the date a judge made the finding, and the owner must report the dog to the local municipal clerk. That is a state-law finding made by a judge after a hearing, which is a different thing from a town’s own registration scheme like New Rochelle’s. The Department also lists “the investigation of animal bites and quarantines” among its responsibilities, with an Animal Vector line at (914) 864-7359.

The county’s 2023 vector-borne disease report counts 1,311 reported Lyme disease cases, and says the blacklegged tick poses “the greatest risk of biting people in the spring, summer, and fall,” while the lone star tick’s greatest risk runs “from early spring through late fall.” That report is about people, not dogs. What a Westchester dog needs for tick prevention is a question for your veterinarian, and we do not offer a protocol on this page.

Our own routing query on OSRM, an open engine built on OpenStreetMap data, measured downtown Dallas to Scarsdale at about 1,571 road miles, to Rye at 1,577 and to Bedford at 1,591, with the engine’s drive times at roughly 28.8, 28.9 and 29.2 hours. That is our query run on 14 October 2026, not a published figure, and it measures distance, not a travel plan. At that length a single leg is not a day trip, so a Westchester handover is something to schedule with the family, not squeeze in.

Our base is North Texas, and we never ship a dog: it travels to its family with us, and the training of the family takes place in the home where the dog will live. Air travel for a large dog is covered in our flying guide. Buying from a seller in another state, start to finish, is the subject of the out-of-state guide. For a Westchester buyer the practical consequence is that the clerk’s answers should arrive before the trip is booked.

Whichever program a family chooses, the one credential you can check without taking our word is the PSA trial record on our about page, where both owners are listed as decoys on trial schedules.

Each question below comes from a section quoted above. Ask them of your own town, village or city, using the clerk’s office as the first stop, and keep the replies.
