Spaying & Neutering Protects Your Pets’ Health

We’re big advocates for spaying female pets and neutering male pets here at Arizona Humane Society. In addition to preventing unwanted litters, altering your pet prior to maturity (at 4–6 months old, or before a female’s first heat cycle) offers the best protection against serious health issues and the development of negative behaviors.

Each year, our skilled veterinarians, who have more than 200 years of combined veterinary experience, perform more than 11,000 spay and neuter surgeries for both owned pets and shelter pets at our Sunnyslope Campus.

A Longer, Healthier Life for Your Pet

Why Spay?

  • Spaying helps prevent serious medical conditions in your female cats and dogs, such as uterine infections, uterine/ovarian cancer and breast cancer.
  • It’s also far less expensive than the cost of treating an infection, having an emergency C-section, treating cancer or raising a litter of puppies or kittens.

Why Neuter?

  • Neutering helps prevent serious medical conditions in your male cats and dogs, such as testicular cancer.
  • It also often has a positive effect on your pet’s behavior!
  • Neutering makes your pet less likely to mark his territory or spray urine throughout the house, and it tends to make your pet less aggressive and less likely to roam.

Solving Pet Overpopulation

Spaying and neutering is the key to solving the pet overpopulation problem in our community. Valley shelters take in more than 50,000 animals every year. By reducing the number of unwanted litters, we can help give more pets a better life.

At AHS, we do our part by spaying and neutering 100 percent of the adoptable dogs and cats in our care. We are also a proud partner of the Alliance For Companion Animals, a group of five local animal welfare agencies who have teamed up to create the “Fix. Adopt. Save.” initiative—a collaborative effort to encourage responsible pet ownership, and to dramatically increase spay and neuter surgeries and pet adoption rates in the Valley.

Preparing for Your Appointment

Spay/Neuter surgeries are offered at our Marge Wright Veterinary Clinic only.

  • Pre-Surgery Instructions

  • There are some specific steps you’ll need to take to prepare your pet for their spay or neuter surgery:

    • All patients scheduled for surgery must have a full meal between 6 p.m. and midnight the night before surgery.
    • For patients under one year of age, please feed another full meal between 5 a.m. and 6:30 a.m. the morning of surgery. (Patients over one year of age should not have another meal.)
    • Please allow all patients to drink water normally without restrictions until check-in for surgery. 
    • If these feeding guidelines are not followed, your pet’s surgery will be cancelled and rescheduled.
    • All pets must be at least two months of age and weigh at least two pounds.
    • Dogs must be on a leash and cats must be in their own individual carrier.
    • If your pet displays fearful behavior towards other animals and/or other people, please bring your pet to his/her appointment wearing a basket muzzle. You may also contact our clinic prior to your appointment for medication to sedate your pet prior to their visit.
    • If your female pet is in heat or pregnant, or your male pet has one or both testicles undescended (cryptorchid) and is accepted for surgery, additional fees will apply.

    Your pet will be ready to go home on the same day, so please be prepared to pick up your pet before 5 p.m.

  • Is Financial Assistance Available?

  • Thanks to generous grants from PetSmart Charities, Circle of Friends and Fix. Adopt. Save, we are able to offer spay and neuter assistance for customers in financial need. Please complete this form and schedule your appointment. We can not guarantee financial assistance but our team will discuss options with you at the time of your appointment.
