Lost Dog on Cape Cod: One Shelter, a Seven-Day Hold, and Fifteen Phone Numbers
Seven days is the window, and it starts when the dog is picked up, not when you notice. Who to call, in what order, and why an unlicensed dog gets a notice on a police noticeboard instead of a phone call.
Cape Cod, Massachusetts11 min readPet Care & Services
If your dog goes missing on Cape Cod, two facts shape everything you do next.
One: there is one shelter that holds strays for most of the Cape, and it is in Brewster, on Route 6A. Towns as far apart as Dennis and Brewster both send their picked-up strays there.
Two: a stray dog is held for seven days. Brewster publishes that plainly as state law, and it is the only hold period any Cape Cod town publishes. Seven days is your window, and it starts when the dog is picked up, not when you notice.
The shelter
Verbatim from the Town of Brewster's animal control page:
"Stray animals picked up by the animal control officer in Brewster are held at the Animal Rescue League, 3981 Main St. (Rte 6A), Brewster, MA 508-255-1030. Stray dogs are held for 7 days by State Law. If the dog is not claimed, it is evaluated for possible adoption. There is no official state holding time for stray cats."
Three things in that paragraph deserve emphasis.
Seven days for dogs, no stated period for cats. If your cat is missing, do not assume a clock is protecting you. Start calling immediately.
"Evaluated for possible adoption" is what happens on day eight. That is not a threat, it is a shelter doing its job, and it is why the seven days matter.
The Animal Rescue League's own site lists that branch address as 3981 Main St (Rte 6A), East Brewster, MA 02631, which matches what Brewster publishes. You can reach the organisation through arlboston.org.
Dennis sends its strays to the same place, and adds a detail Brewster does not. Verbatim from the Dennis leash law and barking bylaw page:
"Unidentified stray dogs are brought to the Animal Rescue League in Brewster and held until an owner claims the dog. The dog owner may reclaim their dog from the Animal Rescue League after licensing the dog in Dennis if the dog owner is a Dennis resident. Dog owners must pay a boarding fee to the Animal Rescue League for each day the animal is impounded."
"The Animal Rescue League can be reached at 508-255-1030 between 10 am and 4 pm. Monday through Saturday."
Read that reclaim condition carefully. A Dennis resident has to license the dog before getting it back. So an unlicensed dog costs you the licence fee, plus any late penalty, plus the daily boarding fee, before you leave the building. Our Cape Cod dog licence guide covers the fees and the four different licence years in use.
And note the hours. 10 in the morning to 4 in the afternoon, Monday to Saturday. That is a narrow window, and it is not a 24-hour line.
Call your own town first, not the shelter
Every town runs its own animal control, so the officer who picked up your dog is a town employee, and the town is where the record lives. Here are the routes towns publish.
Brewster. Verbatim: "If you have lost a pet in Brewster, call the animal control officer at 508-896-7011, ext. 2358. Leave your name, number, and a description of the animal."
Falmouth. Verbatim from its animal services page: "If you have lost pet, please notify Animal Control as soon as possible. In the event that an officer is unavailable at the time of your call, please leave a message and someone will get back to you as soon as possible. Be sure to provide us with a detailed description of the missing pet and a phone number where you can be reached." Emergency animal calls go through the police department at (774) 255-4527, then press 6 for a dispatcher.
Yarmouth. Verbatim from its animal control page: "If you have found a cat, dog, or other pet, please notify us immediately." Emergency animal calls go to (508) 775-0445, then press 0 for a dispatcher, and "An animal control officer will be notified by radio."
Orleans. The police department's animal control function handles it. Verbatim from its animal control page: "The Orleans Police Department's Animal Control responsibilities include the investigation of animal complaints and problems, dog or cat bites, vicious animal complaints, sick or injured wildlife, and barn and kennel inspections." The page notes there is one full-time officer assigned, and that the function was instituted in 2002.
Provincetown. Verbatim from its animal control page: "The Animal Control Officer is dispatched by the Provincetown Police Department." The department number given is 508-487-1212.
Sandwich. If you find a licensed dog in Sandwich, you can look the owner up yourself.
Mashpee maintains a dedicated lost pet page at mashpeema.gov.
Bourne routes licensing questions through the town clerk at 508-759-0600, ext. 1505, which is also where the licence record that identifies your dog lives.
And two towns we cannot give you a number for. Our Cape Cod dog rules guide explains both failures. If you lose a dog in Hyannis or Harwich, call the police department's non-emergency line and ask for animal control.
Here is the same set of routes in one grid, town by town, exactly as each town publishes it.
| Town | Route published for a lost pet |
|---|---|
| Brewster | Animal control officer, 508-896-7011, ext. 2358 |
| Falmouth | Notify animal control; police 774-255-4527, press 6 |
| Yarmouth | Police 508-775-0445, press 0 |
| Orleans | Police department animal control, one full-time officer |
| Provincetown | Officer dispatched by police, 508-487-1212 |
| Sandwich | Animal control, plus a town dog lookup database |
| Mashpee | Dedicated lost pet page |
| Barnstable and Harwich | No verified number; ask police non-emergency |
Why the tag matters more here than most places
Dennis puts the case plainly, verbatim:
"Dogs picked up stray will be returned to their owner if possible, the odds being much higher if the dog is wearing a current Dennis dog license or is microchipped."
Brewster reinforces it, verbatim: "State law requires that all dogs wear a current dog license and rabies tag on their collar. It is a good idea to also have an identification tag on your dog with your telephone number. Cats should also wear a collar and an identification tag. Microchips are a good, permanent identification for your pet. Ask your veterinarian about microchipping."
Three separate identifiers, and you want all three. The licence tag tells an officer which town holds your record. The rabies tag tells them the dog is vaccinated. A plain tag with your phone number on it is the only one that lets a neighbour skip the system entirely and just call you. Our microchipping your pet guide covers keeping the registration current, which is the step most people miss.
Eastham's bylaw requires the tag to be worn, at § 17-5 D, verbatim from the Eastham dog rules PDF: "The dog shall wear around its neck or body a collar or harness to which is securely attached the tag issued for that animal." The same section requires you to keep a copy of the licence at home "in a readily accessible place", and § 17-5 E gives you ten working days to replace a lost tag.
What to actually do, in order
First hour.
Search where the dog was last seen, and take a phone. Provincetown's page gives the standard advice with one Cape-specific twist, verbatim: "Notify local Animal Control Officers. notify local Animal Shelters, notify local Veterinarians and search your neighborhood". The twist is the geography: on a narrow peninsula, a running dog has fewer directions to choose from than in a city, and water on both sides funnels them.
Call your town's animal control and leave a full description even if nobody answers. Every town page above says the same thing about leaving a message.
First day.
Call the Animal Rescue League in Brewster on 508-255-1030, between 10 in the morning and 4 in the afternoon, Monday to Saturday. Call your own veterinarian too, because an injured dog brought in by a stranger arrives there and not at the shelter.
Falmouth's page recommends the social route explicitly, verbatim: "Put up flyers with a photo of the missing pet along with a contact number while you search the area where the pet was last seen. Be sure to speak with neighbors and people in the area and encourage them to report any potential sightings." It also names a specific community resource, verbatim: "Share with other Facebook groups such as Cape Cod Missing Pets."
Provincetown adds the details people forget. Its page tells you to search your neighbourhood, to look under decks and sheds, and, if the missing pet is a cat, to look up in trees. That advice is paraphrased rather than quoted, because the sentence on the town's page is punctuated with a dash character this project does not print.
Days two to seven.
Call the shelter again, daily, in person if you can. Descriptions get recorded imperfectly and a dog that does not match your description on paper may be sitting there.
Call the neighbouring towns' animal control too. Cape town lines are not visible on the ground and a dog that crossed one is in a different town's system.
If your dog is picked up inside Cape Cod National Seashore, the park's law enforcement dispatch runs 24 hours on 617-242-5659, and the park number is 508-255-3421, per its pets page.
The impoundment process, where a town publishes it
Eastham's bylaw is the only one on the Cape that sets out the whole procedure, and it is worth knowing because it tells you what record exists. From § 17-12, verbatim:
"It shall be the duty of the Animal Control Officer, and any assistant Animal Control Officer appointed by the Board of Selectmen, to apprehend any dog found running at large and to impound such dog in an appropriate boarding or other facility."
"The Animal Control Officer or other impounding officer shall keep a register and make a complete record of each impoundment."
That register records the breed, colour and sex of the dog, whether it is licensed, the licence number, the date and place of apprehension, where the dog is being kept, and the owner's name and address if known.
On notification, verbatim: "The owner of an impounded dog, when known, shall be notified verbally or in writing of such impoundment or, if the owner is unknown, written notice shall be posted with the Police Department."
So in Eastham, if your dog is unlicensed and unchipped, the notice goes on a board at the police station rather than to you. That is the entire argument for the tag in one sentence.
And on getting the dog back, in two fragments because the town's PDF breaks the sentence across a page, verbatim:
"The owner, keeper, or other responsible person may reclaim the dog so impounded upon payment of the license fee, if unpaid, and the payment of fees and" "charges for impoundment and board at the place of impoundment, together with any other costs of impoundment."
Our Cape Cod dog fines guide covers what an at-large citation costs on top of that, and our pet emergency preparedness checklist covers having the photograph and paperwork ready before you need them.

How long is a stray dog held on Cape Cod? Brewster publishes seven days as state law. After that the dog is evaluated for possible adoption. Brewster also states there is no official state holding time for stray cats.
What are the shelter's hours? Dennis's page gives 10 in the morning to 4 in the afternoon, Monday through Saturday, on 508-255-1030.
Who do I call first if my dog is missing? Your own town's animal control, then the shelter, then your veterinarian. Brewster's lost pet line is 508-896-7011, extension 2358.
