Foothills Animal Shelter provides low-cost spay and neuter procedures for pets in an effort to reduce pet overpopulation.

Why should you spay/neuter your pets? To keep your pets safe, happy, and healthy! This procedure helps prevent certain cancers and avoids the high cost of caring for litters. It can help prevent bad behavior like running away from home to look for a mate, marking or spraying indoors and some aggression issues.

Your Pet’s Age and Vaccination History

  • Animals must be a minimum of 16 weeks (4 months) and no older than 5 years of age to be eligible for spay or neuter surgery.
  • We highly recommend that puppies and kittens (4 – 6 months of age) are fully vaccinated for Distemper and Parvo prior to surgery.  However, if your puppy or kitten still needs it’s third series of vaccines, we can give these at the time of surgery for a fee. Please bring your pet’s vaccination records with you at time of drop-off.
  • We also highly recommend your adult animal be vaccinated prior to surgery. We can give vaccinations at the time of surgery for a fee. Please bring your pet’s vaccination records with you at time of drop-off.

Your Pet’s Health

  • We are designed to accept healthy animals for surgeries. If your pet has any underlying health problems, the surgery should be performed at a full-service vet clinic.
  • If your pet has been sick lately, it is better to reschedule the appointment than to have the surgery.

Size Limit

  • Unfortunately, at this time we are unable to do surgeries on large dogs that weigh 65 pounds or more. Scroll down to our resources section for organizations that may be able to assist you.
