By spaying or neutering your pet, you are helping to reduce the overpopulation of dogs and cats in your area and assisting to minimize the number of stray or unwanted animals in your community.  

Spaying or neutering doesn’t only prevent unwanted pregnancies, it also has health and behaviour benefits for your pet! Neutering may decreases aggressive behaviours in males; male dogs are less likely to bite, attack or get into dog fights, while male cats are less likely to mark/“spray” and get into cat fights.

Spaying females ends the heat cycle. Female cats can go into heat every 3 weeks – they may attempt to escape to mate or urinate inappropriately. Female dogs can have two heat cycles per year – behavioural changes can occur during heat, such as aggression.

Studies show that spayed/neutered pets, on average, live longer. Spaying eliminates the risk of uterine cancer, ovarian cancer and pyometra (a life-threatening infection of the uterus) and reduces the risk of mammary cancer. Neutering eliminates the risk of testicular cancer and reduces the risk of prostate problems in male dogs.

As a provider of spay and neuter services, we do not assume the role of a primary veterinarian. We recommend that all owners establish a relationship with a veterinarian for continuing care of their animals. 

A full refund will be issued if you cancel 14 days prior to your set surgery/appointment date. If it is less than 14 days to your surgery date, a refund will be issued if we can refill your surgery spot. If your dog goes into heat within a month of your surgery date, please call to rebook your appointment. The GTHS will not provide refunds for owners who have not followed the pre-surgical instructions – animals will be declined for surgery if not fasted, or do not fit our eligibility criteria. 

Pets who are 5 months or older must be fasted the night before surgery, please remove food at 8pm the night before surgery. Always provide water for your pet. Pets who are less than 4 months old may have ½ of their breakfast the morning of surgery.   

Note: If your dog goes into heat in the month leading up to surgery, please call us immediately to rebook your dog’s spay. Any dogs in heat will not be accepted for surgery.

You will be provided with a check-in time prior to your appointment. It is important that you arrive on-time, anyone arriving 15 minutes past their set check-in time will not be accepted for surgery. We ask that you please arrive at the GTHS Animal Hospital with your pet on a leash or in a carrier, follow signage and remain in your car once arriving. If you have any concerns about your pet’s behavourial traits (ex. aggression, fear), please notify us during intake. 

You will be provided with a pick-up time prior to your appointment. Upon discharge, you will be provided with post-op instructions. If you have any questions or concerns directly related to the surgery during the recovery period, please call (705) 445-5204 ext. 221. If there is an emergency after hours, please contact your nearest emergency clinic.
