About Wignall Animal Hospital

Wignall Animal Hospital is a full-service, state-of-the-art, 10,000-square-foot veterinary facility specializing in health care for companion dogs and cats. With the use of the latest techniques in veterinary medicine, our highly trained staff provides complete medical and surgical care for all your pets. Our philosophy is to work with our clients to keep their animals healthy, and we suggest regular preventive care, which lowers the risk of many potentially serious problems.



Wignall Animal Hospital was established in 1970, and we have been providing a high standard of veterinary care to the Merrimack Valley area ever since. We embrace the strict standards of quality required for accreditation by the American Animal Hospital Association (AAHA). We are equipped with the latest medical, surgical, dentistry and diagnostic equipment, a fully computerized record-keeping system, radiography, diagnostic laboratory and life-support equipment, and our compassionate and friendly staff are here every day to serve our clients and patients. For most people, pets are not just animals but are members of the family. At Wignall Animal Hospital, we are committed to helping protect and preserve that bond by partnering with you to offer the best care and quality of life possible for your pets.


Adult and Senior Wellness

We recommend routine physical examinations and vaccinations for young patients and for senior and geriatric patients. Just as with human medicine, as a pet reaches its golden years, we recommend senior-specific laboratory tests to help us gain insight into an aging pet’s health. This screening allows us to have a baseline of what is normal for your healthy pet as well as identify early signs of disease. Early detection allows us to begin treatment as soon as possible for the most favorable outcome.


Pet Boarding and Dog Daycare

While you’re away, allow us to take care of your pets at their home away from home. Your pets can visit Camp Wignall for boarding, daycare, baths, haircuts, and nail trims. Cats, dogs, reptiles, birds and exotic small mammals board year-round at Camp Wignall. Physical examinations, vaccinations, laboratory tests and more can be done during any boarding stay. Plus, they’ll get plenty of exercise in our large turfed outdoor play areas!

We are fastidious about our staff. We only hire staff who are intelligent, knowledgeable, caring and skilled and who love animals. We provide extensive training to new employees, and continuing education and training are ongoing for all staff in order to ensure that we deliver the very best care possible to all our campers and patients. Keeping our staff current on the latest thinking in animal care, behavior and handling are one of our fundamental values, therefore ongoing continuing education is an integral part of working at Camp Wignall.


Payment Plans

Wignall Animal Hospital is happy to offer clients different ways to pay for veterinary care, grooming, boarding, and daycare services. We know that you want the very best for your pet during routine visits and screenings and during sick visits, treatments and surgeries. No matter what service your pet receives, payment plans are an option for you.

We are pleased to offer interest-free payment plans through CareCredit®. CareCredit offers a convenient, low minimum monthly payment program to help you with the best treatment recommendations for your pets. We will assist you with the quick and easy application process.

We know that you want the best possible care for your pet, and we understand that it is easier to provide that care when you can budget accordingly. We offer Essential Care Plans which allow you to provide high level care with regular affordable monthly payments. These plans offer discounts on core vaccines and annual wellness services as well as additional discounts for flea, tick and heartworm preventives and medical services! You can also add spay, neuter, microchipping and dental services!


Pet Insurance

Pet insurance is becoming more and more popular as more pet owners realize how they and their pets can benefit from it. We have information available for coverage provided by Trupanion®, and we recommend that you purchase insurance when your pet is a puppy or kitten, as you’ll benefit from the insurance more the longer your pet is covered.
