To help ensure that there are enough homes for all pets, we play an active role in reducing the number of homeless animals born by offering low cost surgery to spay or neuter dogs and cats.  As a service to our adopters, we provide a free spay/neuter surgery with every adoption. We operate a spay/neuter clinic for pet owners throughout our community. The clinic is staffed by licensed professional veterinarians, veterinary technicians and veterinary assistants.


An appointment is required for each surgery by calling the shelter at (208) 746-1623

During the hours 10am-5pm, Monday through Saturday *Closed from 1pm - 2pm

Pre-Surgery Instructions

  • Healthy pets only. Please let us know if your pet has ever been treated by a veterinarian for a health problem so we can evaluate risk adequately. The clinic opens at 8:30 a.m. Please plan to be there approximately 15 minutes to meet with a veterinary technician. If you are not at the clinic before 9:30 a.m., your appointment may be forfeited.
  • You will be required to sign an anesthesia waiver explaining surgical risks.
  • All pets must be at least 3 lbs and at least 3 months old
  • Cats are required to have FCRP and rabies vaccines
  • Dogs are required to have Kennel Cough, DA2PPV and rabies vaccines (Please bring proof of current vaccines from your veterinarian. If your pet is not up to date, our veterinarians will give the vaccines for $15.00 each on the day of surgery.)
  • Small dogs and cats must be in secure individual carriers
  • Larger dogs must have a secure collar and leash
  • Don’t feed your pet after 8:00 PM the night before. Always keep fresh water available for your pet. Kittens and puppies under 6 months old should have a small breakfast (1 or 2 spoonfuls) before they come to surgery to assure their blood sugar doesn’t get too low. We will monitor them after they are admitted.
  • Pick up all surgery pets between 3:00 and 4:30.

Surgery After Care Instructions

EXERCISE:  Restrict your pet’s activity for the next 7 days. No running, jumping, swimming or bathing for TWO WEEKS. Swimming or bathing will increase the risk of infection and cause the incision to open.

INCISION:  You should check your pet’s incision every day until it is healed (7-10 days). DO NOT allow your pet to lick or chew at the incision. There will be a little tenderness and some nausea. An occasional vomit for a day or two is considered normal but should stop by 48 hours.

SUTURES:  Absorbable sutures were used and do not need to be removed. The surgery site may show a little bruising. Several layers of sutures may feel like a lump under the skin to you. That is normal.

ANESTHESIA & PAIN MEDICATION: Your pet might still be groggy (especially pets that had surgery later in the afternoon). Anesthesia and injectable pain medications make them feel cool, so please keep them indoors in a warm, protected, quiet place.

FOOD:  Wait until your pet is completely awake before offering food or water. Then offer only small portions of food the first day after surgery. Nausea and occasional vomiting is normal and should stop within a day.

AFTER CARE:  If you have any concerns about your pet’s condition after surgery, please contact the Lewis Clark Animal Shelter at (208) 746-1623 during normal business hours 10-5.

PLEASE NOTE:  As stated in your signed waiver – we are a  part time spay/neuter service for pet owners who need assistance paying for this service. We can not provide 24 hour follow up care. In the rare occurrence that your pet has an adverse reaction or complication related to this surgery and must be examined immediately or after hours please call your local veterinarian. You are responsible for all costs incurred.
