It's all we do.
We are committed to reducing the pet population and controlling high euthanasia rates, as well as improving the health of your animal.

Why Spay or Neuter?

For your pet's health, and for your peace of mind.

To spay or not to spay, that is the question.

Spaying or neutering your animal helps control the pet population, and in some cases, improves the health of your pet. Spaying and neutering can help reduce the chance of mammary tumours, ovarian cancer, testicular cancer and prostate cancer.

It can also help reduce undesirable behaviours like aggression, humping and urine marking, and can reduce the desire to roam.

And it helps reduce the number of unwanted pets that have to be euthanized every year. That's tragic.

  • Age

    Animals can be spayed or neutered anytime after 4 months of age.

  • Our Surgeries

    All surgeries are performed by our three licensed Veterinarians. Our staff of Registered Veterinary Technicians and Veterinary Assistants helps keep our clinic running smoothly. We use the highest standard of equipment, including a fear-free approach and pain control.  

Not Just Surgeries

We are a community clinic.
Our goal is to help your pets, and to help other pets in the community.
Every month we pick a different animal rescue, and donate the funds from our bottle drive.


Microchipping can identify your dog or cat if they get lost. It also gives you some peace of mind!

Microchipping can easily be done during surgery.

Book your microchipping at the same time as you book surgery.

Bottle Drop Off

We are a drop-off centre for recycled bottles. Our volunteers clean and sort the bottles to help the shelter or rescue of the month.

Please drop off your returnable bottles behind the fence.

What do I need to do?

It's easy as 613-345-SPAY

  1. Fill out the Surgical Booking Form and we will book your appointment based on the time frame you selected.  If the appointment date is not convenient, it's a quick call to move your appointment to a more suitable day.
  2. Call 613-345-7729 once you have sent us your form if you have any questions.  We do not book appointments by phone.
  3. A $50 non-refundable deposit is required at the time of booking (e-transfer) and the balance is due the day before surgery. Once we have received your deposit, we will book you an appointment.
  4. Drop your pet off at the appointed time the morning of surgery. Dogs must be on leash and cats must be in a carrier.

What to do the day of surgery

No food after 8pm the night before and no water after midnight!


Medications - please let us know of any medications that your pet is taking, including supplements and CBD oil.

Medications and supplements may have an interaction with the anesthetic and pain medication that your pet will receive in the clinic.

It is much safer for the health and recovery of your pet if we know what your pet is taking before surgery.

Morning Drop Off

We ask all of our patients to be dropped off between 7:00 - 9:00 am the morning of surgery.

Follow our roundabout behind the clinic and please remain in your car with your pet. Our staff will come to your car and help guide you through the process.

Pick up time varies from 2-5pm. Recovery times can be longer if your pet is on other medications.

Your pets will be well taken care of!


All surgeries run the risk of complications.

We commonly see a few complications with spay/neuter surgeries including pregnancy, illness, hernias and cryptorchidism.

If we find any complications with your pet, we will contact you immediately about options. Please leave a number where you can easily be reached.

Fleas. For the safety of all of our animals, if we find fleas on your pet we will treat them and then put them in isolation for a few hours. Since mornings are very busy, we will contact you later in the day about fleas and any added expenses that this may incur.
