Spay + Neuter surgery is available at SayulitAnimals every Wednesday. We also do quarterly 3-4 day campaigns in neighbouring towns such as San Ignacio, Punta de Mita, Higuera Blanca and many small towns that you’ve never heard of! All our sterilizations are FREE or with a pay-as-you-can donation. NOTE: For our weekly Thursday clinics, as we can only do up to 10 animals in these clinics, please make sure you make an appointment as much in advance as possible and have your animal prepared and ready to go!


Spaying (for females) and neutering (for males) is a surgical procedure, performed by a trained and seasoned Veterinarian, which renders a dog or cat incapable of reproducing.

But in addition to halting reproduction, there are numerous health benefits associated with the procedure. For example, spaying females prior to their first heat cycle nearly eliminates their risk for breast cancer and prevents uterine infections and uterine cancer. Neutering males prevents testicular cancer and greatly reduces the risk for perianal tumors.

If a first heat has already occurred, spaying eliminates the usual crying and pacing of the female cat in heat; while spaying a female dog eliminates the messiness associated with her cycle. Neutering of male cats and dogs can also prevent undesirable sexualized behaviors such as urine marking, humping, male aggression and the urge to roam.

Additionally, if you have more than one pet in your household, all your pets will generally get along much better if they are all neutered.


There are a few things you can to do make the process as pain-free as possible, for both you and your pet.

  • Call 329-291-3974 or drop by our office to set up your appointment
  • Make sure the dog or cat has no food and very little water 8 hours prior to surgery
  • Bring the animal to the clinic between 9:30-10:30am. NOTE: If you bring the animal in after 10:30am, you will lose your appointment.
  • Try to bring a collar and leash for dogs, a secure container with air holes for cats, and a blanket or towel for after the surgery.
  • When you pick up the animal, don’t leave without one of our AFTER CARE information sheets!
  • Finally, help us continue to offer this service to the community by making a donation on behalf of the animal.


  • Put your pet in a safe, clean place in your house until it is fully-recovered from the anesthesia. Your pet will be tired after the operation and will need up to 48 hours to recover.
  • Don’t let your pet lick the wound.
  • Your pet mustn’t run, swim or bathe for a week after the operation.
  • Check the wound daily. Some swelling or redness is normal, but pus is a sign of infection, and must be treated by a Veterinarian.
  •  Stitches don’t need to be removed, as they will dissolve as the wound heals.


  • Not eating after 48 hours.
  • Lethargic, low energy, sadness after 48 hours.
  • Excessive swelling and redness in wound, or signs of pus.


NOTE: If you see any of these warning signs, please immediately contact your personal Vet or Dr. Grethel (who performs all of our Wednesday surgeries), at 311-166-1609, so that they can assess the situation. If we are not available, please take your animal to the nearest Veterinarian immediately.
