Preparing for Surgery

Pre-Operative Instructions

Due to the high-volume requirements of our clinic’s operations, we are unfortunately unable to perform surgery on dogs weighing more than 90 pounds, bilateral cryptorchid cats, or abdominal cryptorchid dogs.  These animals – based on their physical characteristics, temperament or health concerns – would be best assisted at a full-service veterinary clinic, and may be declined for surgery at the WHS Spay & Neuter Clinic.

You must make an appointment and pay a $20 deposit for cats or $40 for dogs, which will be applied toward your final balance. Call us at 503-480-SPAY (7729) to schedule your pet for surgery, or fill out and submit an online appointment form.

This clinic does not have the capacity to treat sick or injured animals. If your pet is sick or injured, please call your regular veterinarian. We provide an elective surgery for healthy pets only.


We recommend that you have your pet vaccinated at least two weeks prior to your appointment. We recommend that you abide by Oregon state law and have a current rabies vaccination for your pet. If your pet does not have a rabies vaccine, we can administer it at the time of surgery for a charge of $10.


All adult animals must have food taken away by midnight (12 am) the night before surgery and must be kept indoors or confined. Any animal that remained outside all night without being confined will not be admitted for surgery. Animals four months or younger may have food until 6 am the morning of surgery. All animals may have water available until the morning of surgery.


Check-in time is at 7:15 – 7:30 am. Any late arrivals will be declined for surgery due to a strict surgical schedule we must maintain.


Please leave your pet in the car until you have completed all of the required paperwork. A veterinary assistant will advise you when to retrieve your pet.


You must complete the necessary admission forms when you arrive. You may stop by the clinic prior to your pet’s scheduled surgery day and pick up the paperwork to save time the morning of your appointment. Admission forms typically take 10-15 minutes to complete.


We accept cash, debit cards and credit cards. Sorry, we cannot accept checks. Services must be paid for at the time of check-in.


All dogs must be on a leash and all cats must be in a carrier. If you do not have a carrier for your cat, you can purchase a cardboard carrier for $5.


All animals are released the day of surgery and must be picked up at 4 p.m. Animals not picked up on time the day of surgery will be charged a $10 late fee.
