Tie-outs, pens, shelter

Massachusetts dog tethering law

Massachusetts has a tethering law detailed enough to specify the weight of a chain and the height of a cable run. This page lays it out in the order an owner meets it: the tie-out, the pen or yard, the shelter, the weather, and what happens on a complaint. It is general information rather than legal advice, and your town's animal control officer can say how it applies to a particular yard.

The tether itself

Five hours in twenty-four, never outside overnight, and never a puppy

Section 174E(a) sets the core limit. No person owning or keeping a dog may chain or tether it 'for longer than 5 hours in a 24-hour period and outside from 10:00 p.m. to 6:00 a.m.,' unless the tethering is for no more than 15 minutes and the dog is not left unattended. The sentence is compressed. Read plainly, it sets two limits, a five-hour daily cap and no outdoor tethering overnight, each subject to the same short, attended exception; if your situation depends on the exact reading, ask animal control or a lawyer.

The same subsection governs the equipment. The tether must not let the dog leave the owner's or keeper's property, it must be designed for dogs, logging chains and other lines not made for tethering dogs are banned, and no chain or tether may weigh more than one eighth of the dog's body weight. No dog under 6 months old may be tethered outside for any length of time. The section says outright that walking a dog on a hand-held leash is not affected.

  • No more than 5 hours of tethering in any 24-hour period
  • No tethering outside from 10 PM to 6 AM
  • The exception: 15 minutes or less, with the dog attended
  • A tether made for dogs, weighing at most one eighth of the dog
  • No outdoor tethering at all for a dog under 6 months

Pens, yards and runs

A dog may be kept outside in a pen, a fenced yard or a cable run built to the statute

Subsection (b) lists three ways to confine a dog outdoors. A pen or secure enclosure must give at least 100 square feet of exercise space, be built of chain link or similar material as determined by the building inspector, be enclosed on all four sides, and be tall enough to hold the dog; commercial kennels with pens meant for temporary boarding are exempt from the 100-square-foot figure. The second option is a fully fenced, electronically fenced or otherwise securely enclosed yard, where the dog can run but cannot leave.

The third is a trolley or cable run, with conditions. Only one dog may be attached to each run. The tether clips to a properly fitting collar or harness with room for two adult fingers at the throat, and never to a choke or pinch collar. There must be a swivel on at least one end, the tether and the cable must each be at least 10 feet long, and the cable must sit between 4 and 7 feet above the ground. The reach must allow constant access to water and shelter without letting the dog leave the property, reach an edge or tangle.

Outdoor methodWhat section 174E requires
Pen or secure enclosureAt least 100 square feet, chain link or similar, all four sides enclosed, tall enough to hold the dog
Fenced yardFully, electronically or otherwise securely enclosed; the dog can run but cannot leave
Cable run or trolleyOne dog per run; tether and cable each at least 10 feet; cable 4 to 7 feet high; a swivel; no choke or pinch collar
Any outdoor confinementClean water and a dry, roofed shelter enclosed on three sides with a solid floor

Shelter and weather

The shelter has a written standard, and a weather advisory brings the dog inside

Subsection (c) requires clean water and 'appropriate dog shelter' for any dog confined outside. The shelter must keep the dog dry and protected from the elements, be fully enclosed on at least three sides, and have a roof and a solid floor. Its entrance must be flexible enough for the dog to come and go and sturdy enough to block the weather. Inside there must be clean bedding, and the space must be small enough to hold the dog's body heat yet large enough for it to stand, lie down and turn comfortably, with drainage that keeps water, ice and waste from pooling.

Subsection (d) is the weather rule. A dog may not be left outside when a local, state or federal authority has issued a weather advisory, warning or watch, or when heat, cold, wind, rain, snow or hail pose an adverse risk given the dog's breed, age or physical condition, unless the tethering is for no more than 15 minutes. On Cape Ann that makes the National Weather Service office in Boston part of an outdoor dog's routine: a winter storm watch ahead of a nor'easter, or a heat advisory in July, is the signal to bring the dog in.

  1. 01

    Check the National Weather Service forecast for Boston and Cape Ann each morning

  2. 02

    If any advisory, watch or warning is in effect, keep the dog indoors

  3. 03

    Refresh the water, and in winter make sure it has not frozen

  4. 04

    Change the bedding and clear standing water or ice around the shelter

  5. 05

    Keep a rough log so tethering stays under 5 hours in 24

  6. 06

    Bring the dog in before 10 PM

Exceptions and enforcement

Two narrow exceptions, a cruelty clause, and fines that rise to $500

Subsection (e) allows exceptions reasonably necessary for a dog's safety in two settings: a camping or recreational area, under that area's own policy, and a dog actively herding cattle or other livestock or working in agriculture as part of a business. Subsection (f) then bans cruel conditions and inhumane chaining or tethering at any time, naming filthy confinement with excessive waste, garbage, dirty water or dangerous objects; taunting, prodding, hitting or harassing a tied or confined dog; and exposing it to dangerous conditions, including attacks by other animals.

Penalties under subsection (g) climb with each offense: a written warning or a fine of up to $50 for the first, up to $200 for the second, and up to $500 for a third or later offense, with possible impoundment at the owner's expense pending compliance, or loss of ownership of the dog. Cities and towns enforce the section through animal control and police. If an animal control officer contacted by the MSPCA or the Animal Rescue League of Boston is unresponsive or unavailable, a special officer appointed at their request may enforce it instead.

  • First offense: a written warning or a fine of up to $50
  • Second offense: a fine of up to $200
  • Third or later: up to $500, plus possible impoundment or loss of ownership
  • Enforced by animal control or police, with MSPCA and ARL officers as a backstop

Better than the tie-out

A fenced playgroup gives an outdoor dog what a tie-out cannot

A tie-out is a way of keeping a dog outside for longer than anyone can stand there with it. A daycare day answers the same need without the clock: the dog spends it in a playgroup of 7 to 10 dogs matched by size and temperament, on a fenced turf yard with pools and platforms, with indoor play floors for storm days. Daycare costs $42 for a full day and $33 for a half, and a dog who comes most weekdays may be better served by the $700 unlimited monthly membership.

For a dog who needs a midday break rather than a whole day, our at-home walks are solo and leashed: 20 minutes for $25, 30 for $35 or 60 for $55, with a photo and a note after every walk. Ask us whether we cover your address. The Pup Van runs in Gloucester, Rockport, Essex and Manchester-by-the-Sea at $10 each way, and every dog begins with a free evaluation on a weekday morning between 6:30 and 9:30.

Asked and answered

Questions people ask about this

Short, complete answers you can act on today. More in the full FAQ.

How long can a dog be tied outside in Massachusetts?
No more than 5 hours in a 24-hour period under section 174E, and not outside between 10 PM and 6 AM, unless the tethering lasts 15 minutes or less and the dog is attended. Puppies under 6 months may not be tethered outside at all, and any dog kept outdoors needs clean water and a proper shelter.
Is an electronic fence legal for a dog in Massachusetts?
Section 174E(b) lists an 'electronically fenced' yard among the permitted ways to confine a dog outside, as long as the dog can run in the yard but cannot leave it. The water and shelter requirements still apply to any dog kept outside, and so does the rule about weather advisories, warnings and watches.
What counts as a weather advisory for an outdoor dog?
Section 174E(d) refers to a weather advisory, warning or watch issued by a local, state or federal authority, which includes the National Weather Service. It also covers extreme heat, cold, wind, rain, snow or hail that pose an adverse risk given the dog's breed, age or physical condition, even when no advisory has been issued.
Who do I call about a dog chained outside in a storm?
The animal control officer or the police in that city or town, who enforce section 174E. If animal control does not respond, the statute lets special officers appointed at the request of the MSPCA or the Animal Rescue League of Boston step in. Give the address, the time and what you saw, and stay off the property.
Does the law say how big a dog house must be?
It sets a standard rather than measurements: small enough to retain the dog's body heat, large enough for it to stand, lie down and turn comfortably, enclosed on at least three sides, roofed, with a solid floor, clean bedding and a flexible entrance that blocks the weather. Drainage must keep water, ice and waste from standing in or around it.
