New Hampshire has well over a hundred places to take a sick or injured pet, spread across ten counties from the Merrimack Valley mill cities to the White Mountains. The right one depends less on the name over the door and more on where you live, what species you own, and what time the problem starts. This page explains how veterinary care is organized in the Granite State and how to use the listings below to reach a practice quickly.

Every hospital listed here is a private business. There is no state-run animal hospital network, and county government does not operate clinics. That makes your own research important, and it is easier than it sounds.

Who Regulates Animal Hospitals in New Hampshire

Veterinarians in New Hampshire are licensed by the Board of Veterinary Medicine, which sits within the Office of Professional Licensure and Certification. The practice of veterinary medicine is governed by RSA 332-B. A veterinarian must hold an active state license to diagnose, treat or prescribe for animals, whether the building is called a hospital, a clinic or a veterinary center.

The license belongs to the person, not the building. If you want to check credentials, search for the veterinarian's name on the state's license verification tool. The same board accepts complaints about professional conduct. Billing disputes and customer-service problems are usually better settled with the practice manager first.

Animal disease control is a separate job. The State Veterinarian works within the New Hampshire Department of Agriculture, Markets & Food and oversees reportable animal diseases, livestock health and animal import rules. Veterinarians accredited by the USDA issue the interstate health certificates that you need when you travel with a pet across state lines.

Town government touches your pet too. Under state law, dogs must be licensed each year through the town or city clerk, with an April 30 deadline. The clerk will ask for proof of a current rabies vaccination. That proof comes from your veterinarian, so the animal hospital visit usually comes first and the clerk visit second.

Metro Corridor, Seacoast and Rural North: How Access Differs

Most animal hospitals cluster along the I-93 and Route 3 corridor and in the southeastern corner of the state. Rockingham County has the most listings, with practices in Windham, Derry, Salem, Londonderry, Brentwood, Hampstead, Exeter, Stratham and Portsmouth. Examples include Derry Animal Hospital on Tsienneto Road, Salem Animal Hospital on South Broadway, Crossroads Animal Hospital on Nashua Road in Londonderry, and Exeter Veterinary Hospital on Stratham Heights Road.

Hillsborough County comes second, and Manchester and Nashua have six listings each. Best Friends Animal Hospital is on Brown Avenue in Manchester. State Line Veterinary Hospital is on Daniel Webster Highway in Nashua, and Mercy Animal Hospital is on the same highway in Merrimack. You will also find Bedford Animal Hospital on Old Bedford Road, Hillsborough County Veterinary Hospital on Pine Road in Amherst, and Acorn Acres Cat Clinic on Lowell Road in Hudson.

In Merrimack County, Cilley Veterinary Clinic is on Iron Works Road in Concord. One detail trips people up: Manchester Animal Hospital is at 1129 Hooksett Road in Hooksett, not in Manchester. Always read the street address before you set the GPS.

Elsewhere, practices are spread more thinly. Park Place Veterinary Hospital on Old Homestead Highway in Keene anchors the Monadnock region in Cheshire County. Meredith Animal Hospital on Route 104 serves the Lakes Region. Conway Veterinary Hospital on White Mountain Highway and Meadow Pond Animal Hospital on Route 16 in Ossipee cover the Mount Washington Valley area. Rochester Animal Hospital on Old Gonic Road and Great Falls Veterinary Hospital on Route 108 in Somersworth serve the Strafford County side of the state.

North and west of the lakes, the map empties out. Coos County has only two listings and Sullivan County has three. Owners there often drive a long way for a visit, and winter weather can lengthen the trip. In practice, metro residents can compare several hospitals within a short drive, while rural residents may have one realistic choice. If that is you, build a relationship with that practice early, before an emergency forces the issue.

Emergency and After-Hours Care in the Granite State

Emergency options are concentrated in the south. Rockingham Emergency Veterinary Hospital, at 3 Cobbetts Pond Road in Windham, is the emergency practice in our listings and sits within reach of the I-93 corridor. Port City Veterinary Referral Hospital, at 215 Commerce Way in Portsmouth, serves the Seacoast. As a referral hospital, it typically handles specialty cases arranged through your regular veterinarian. Hours, staffing and services can change, so call before you drive.

Outside those areas, your first call is often your own veterinarian's after-hours recording, which usually names the nearest open hospital. In the Lakes Region, the White Mountains and the North Country, that drive can be long. Phone ahead so the team can prepare for your arrival, and ask for first-aid steps you can take in the car.

Common New Hampshire emergencies include porcupine quills, tick-borne illness, antifreeze or ice-melt exposure in winter, collisions with wildlife on rural roads, and heat stress in summer. Bring the packaging from any suspected poison, a list of your pet's medications, and a towel or muzzle for safe transport. Never give human pain medication to a pet unless a veterinarian tells you to.

Preparing for Your First Visit to a New Hampshire Animal Hospital

Most practices ask new clients to call or book online first. Busy areas such as Manchester, Nashua and Salem may have waits for routine appointments, so call early. A little preparation speeds up the visit.

New Hampshire has no statewide fee schedule for veterinary services, so prices vary by practice and by region. For non-urgent work such as dental cleanings or spay and neuter surgery, compare written estimates. Tell the front desk if you have a budget limit. A good practice will talk through the options with you.

Animal hospitals in New Hampshire are licensed by the state veterinary medical board and may also hold accreditation from the American Animal Hospital Association. State regulations govern facility standards, controlled substance handling, and continuing education requirements for all licensed veterinary professionals.

Animal Hospital locations are available in 76 cities across New Hampshire. They are spread across 10 counties.

Cities with the highest concentration include Nashua, Manchester, Amherst, which tend to have more animal hospital facilities due to higher pet ownership rates and the presence of veterinary specialty practices in metropolitan areas.

Pet owners in New Hampshire should identify both a primary care veterinarian and the nearest 24-hour emergency animal hospital before a health crisis arises, as preparation can be critical during after-hours emergencies.

Regional Search Tips for Pet Owners Across New Hampshire

Start with your county, then narrow by town. In Grafton County, Stonecliff Animal Clinic of New Hampshire on Mechanic Street in Lebanon serves the Upper Valley. Many households there live close to the Vermont line and may compare practices on both sides of the Connecticut River. Whichever side you choose, keep your pet's records in one place.

In Carroll County, Conway Veterinary Hospital on White Mountain Highway and Meadow Pond Animal Hospital on Route 16 in Ossipee serve a region that swells with visitors and second-home owners in summer, foliage season and ski season. If you split the year between homes, register as a client before you need urgent care and ask the practice to keep your records on file.

Before you call any listing, write down your pet's species, age, weight and symptoms, and keep your previous veterinarian's number handy. Ask about hours, whether the practice is accepting new clients, and how it handles after-hours calls. Phone numbers in our listings are a starting point, so confirm them with the practice itself.

New Hampshire Animal Hospital FAQs

Dogs are licensed each year through the clerk in the town or city where you live, and the state deadline is April 30. The clerk will ask for a current rabies vaccination certificate, which your veterinarian provides after giving the vaccine. If your dog is spayed or neutered, bring that paperwork too, since fees can differ by status. Some towns let you renew by mail or online, so check your clerk's website. Late licensing can bring fines, so do not wait until the last week of April. Book the rabies visit well ahead of the deadline.

Start with the practice manager or the veterinarian, since many billing and communication problems are solved with a direct conversation and a copy of your estimate and invoice. If the concern involves professional conduct, such as suspected negligence, you can file a complaint with the New Hampshire Board of Veterinary Medicine, which is part of the Office of Professional Licensure and Certification. The board can also confirm whether a veterinarian's license is active. It does not set prices and generally cannot order a refund. Keep your records, dates, names and written estimates, because the board will want specifics.

Rockingham Emergency Veterinary Hospital at 3 Cobbetts Pond Road in Windham, 603-870-9770, is the emergency hospital in our listings. Port City Veterinary Referral Hospital at 215 Commerce Way in Portsmouth, 603-433-0056, serves the Seacoast as a referral hospital. Call before you drive. Staff can tell you whether they are accepting patients, what the wait looks like and what to do on the way. Hours and services change, so confirm them directly. In the Lakes Region or North Country, phone your regular veterinarian's after-hours message first, since it often names the closest open option.

Our listings include Acorn Acres Cat Clinic at 225 Lowell Road in Hudson, 603-595-2287, whose name points to a feline focus. Call to confirm which services it offers and whether it is taking new patients. Many general animal hospitals also see cats, and some offer quieter exam times or separate waiting areas. Ask whether a practice has cat-friendly handling or a veterinarian with a special interest in feline medicine. Under New Hampshire law, cats need rabies vaccination too, including indoor cats. A carrier lined with a towel makes the visit calmer for everyone.

Coos County has two listings and Sullivan County has three, so choices are limited. Call before visiting, because a small practice may reserve certain days for surgery and have limited room for walk-ins. Ask which hospital it refers overnight cases to. Depending on the road, some owners on the northern and western edges also use practices in neighboring counties, such as Conway Veterinary Hospital in Carroll County or Stonecliff Animal Clinic in Lebanon. Build a relationship with one practice before an emergency, keep records on your phone, and check road conditions before winter trips.

Ticks are a real concern across much of the state, and the blacklegged tick that carries Lyme disease lives in woods, brush and leaf litter. Ask your veterinarian which tick preventive suits your pet, whether the Lyme vaccine makes sense for your dog's lifestyle, and how often to test for tick-borne infections. Ticks can be active on mild winter days above freezing, so many owners keep preventives going year-round. Check your pet after walks, especially around the ears, armpits and base of the tail, and bring a removed tick to your appointment if you can.
