Is this an emergency?

The numbers a veterinary team checks first. If you are worried at all, the answer is to call — but this is what we would be looking at.

Call us now, do not wait

  • Gums that are white, blue, grey or yellow
  • Trying to vomit repeatedly with nothing coming up, especially a deep-chested dog
  • Struggling to breathe, or a cat breathing with its mouth open
  • Straining in the litter box without producing urine — a male cat, urgently
  • A seizure, collapse, or unresponsiveness
  • Any suspected poison, human medication, or chocolate
  • Bleeding that will not stop, or an injury from a car

General reference ranges for healthy adult animals. Puppies, kittens, small breeds and stressed animals sit higher. This is background, not a diagnosis — nothing here replaces a look from a veterinarian.

When we are closed

Monday–Friday 8:00–6:00 · Saturday 8:00–1:00 · Closed Sunday

We do not run an overnight service, and an emergency should not wait for us to open. Connecticut has 24-hour emergency and specialty hospitals within reach of Watertown — worth finding the nearest one and saving the number in your phone before you need it, not at eleven o'clock at night.

During our hours, call us first: 860-274-2212.

Living here

Ticks are a Connecticut problem, not a summer one.

Lyme disease is named after Lyme, Connecticut — about an hour from this building. The state sits among the highest-incidence states in the country, and the Connecticut Department of Public Health counted roughly 2,200 human cases in 2024. Our dogs walk through the same grass.

Darker months carry the higher risk. Activity climbs from about April and peaks in late spring, with a second rise in autumn — and adult ticks stay active any winter day above freezing. Which is why prevention here is a twelve-month conversation, not a June one.

Worth asking us about at your next visit: year-round tick prevention, the Lyme vaccine for dogs, annual screening, and what to do the day you find one attached.

Watertown Animal Hospital’s video library connects here at launch.

Room 02

Waiting Room

Watertown Animal Hospital has been Watertown's family vets for more than 70 years, at 673 Litchfield Rd.

Eddy has been very good today.

He would like you to know that.

In their own words

“We have taken our cats to the Watertown Animal Hospital for many years. I recommend them to many people. The best part is the staff. From the receptionists to the doctors, each is kind and thoughtful. The doctors are so knowledgeable. They have helped our cats through many problems. And at the times of loss, they are very compassionate. They are like family. This animal hospital has it all.”

Richard Naiss

“Great place really cares for dogs and I can stay by her side which is great since she gets scared.”

Eileen Egan

“They were really nice there and welcoming to my pup and me. Thunder loved all the attention he was getting from the vet and vet tech. He loves his stuffed animal that he got there.”

What those five letters actually mean

Diplomate of the American College of Veterinary Surgeons. The veterinary equivalent of a specialist surgeon.

TrainingVeterinary school, then an internship, then a surgical residency of several more years — followed by a board examination with a reputation for being brutal.
How rareMost general practices have no board-certified specialist at all. Surgical cases get referred to a specialty hospital, often an hour or more away.
For youA surgical opinion, in Watertown, from someone who spent years training in nothing else.

Room 05

Internal Medicine

Lisa Keno, DVM, DACVIM

Dr. Keno is a Diplomate of the American College of Veterinary Internal Medicine (DACVIM) — a board-certified specialist in internal medicine, seeing referred and complex medical cases alongside the general team.

What those six letters actually mean

Diplomate of the American College of Veterinary Internal Medicine. The veterinary equivalent of a specialist physician.

TrainingVeterinary school, then an internship, then a multi-year residency in internal medicine, then board certification.
The workThe complicated ones. The pet who keeps drinking and keeps losing weight. The bloodwork that does not add up. The illness that has been going on for months without a name.
For youThe second opinion is already in the building.

For referring veterinarians

If you are a general practice in Litchfield County or the Naugatuck Valley and you have a case you would normally send to Hartford or New Haven — it may not need to travel that far.

  • Internal medicine — Lisa Keno, DVM, DACVIM
  • Surgery — Debra Weisman, DVM, MS, DACVS

Your client stays close to home, your relationship with them stays intact, and the case comes back to you.
