Spay & Neuter

No question about it!

Spay and neuter your pets and neighborhood strays

PAHS believes that the most important thing to do for the welfare of animals is to spay or neuter them, so that every puppy, kitten, or rabbit born may find a loving and responsible home. One spay or neuter surgery provides a lifetime of peace and prevents many lifetimes of suffering. Each year, millions of animals are euthanized at shelters across the country due to accidental breeding by free-roaming, unaltered pets.

Call us for advice on:

  • • Spaying or neutering your pet
  • • Spaying or neutering stray or unapproachable cats
  • • Spaying or neutering on limited household incomes

Spay and Neuter Fund

Because of its beliefs, PAHS has dedicated a significant portion of its annual budget to subsidize the spaying and neutering of homeless animals and pets of owners with financial need.

PAHS’ Spay and Neuter Fund provides critical funding to underwrite spay/neuter surgeries for homeless animals and animals from low-income households. PAHS’ vouchers are used at partnering Bay Area spay/neuter clinics. Contact PAHS to inquire about spay/neuter support and availability of funding assistance. For information on our CatWorks, RabbitWorks, and RodentWorks spay and neuter programs, click here.

Our spay/neuter vouchers are made possible by donations from the public and from friends of the Palo Alto Humane Society. We receive no government funding. Please give and have the satisfaction of knowing your donation prevented countless animal births contributing to pet overpopulation.

PAHS annually underwrites the neutering of 1,000-2,000 animals through our Spay and Neuter Fund.

Please donate if you would like to support this vitally important program.

Pigs are very intelligent animals, often regarded by scientists as being the most intelligent of livestock.

A hot car is no place for a pet. Leaving a dog or cat in a parked car during the warmer months can cause serious injury or death within minutes.

Temperatures inside a car can reach 120° in a matter of minutes, even with the windows partially open. Shade and having water will do little to help.

The safest place for your companion is in the coolest part of the house with plenty of fresh water to drink.

If you see a companion animal inside a parked car during hot weather, and they appear in distress, call animal control or the police immediately.

Signs of distress include: Heavy panting, glazed eyes, unsteadiness, listlessness, vomiting and a over-red or purple tongue.

Don't force your companion animal to exercise after a meal in hot, humid weather. Do it in the cool of the early morning or evening.

If you and your dog go to the beach, be sure you can find shade and plenty of fresh water. Rinse her off after she has been in salt water.

With only hot air to breathe, a dog's process of cooling through panting fails. A body temperature of 107 degrees may cause brain damage or death.

If a dog is overheated, provide emergency first aid by applying TEPID water all over the body, and then gradually applying cooler water. Seek veterinary care.

A dog's paws can be burnt by hot pavement. Do not make them stand on hot pavement for long periods and keep walks on hot asphalt to a minimum.

Be sensitive to old and overweight animals, and those with heart or lung diseases. They should be kept indoors in air conditioning and out of hot weather.

Snub-nosed dogs (like Pekingese, Bull dogs, Boston terriers, Lhasa apsos, Shih tzus, and Pugs) should be kept indoors in air conditioning and out of hot weather.
