Spay Abortion: Why would a rescue choose to terminate a pet pregnancy?

When a pregnant dog or cat enters a rescue or shelter, many organizations will choose to immediately spay her, thus ending the pregnancy.

Pet overpopulation and shelter capacity

Most US shelters operate at or over capacity at all times; the sheer number of pets in need is more than the animal welfare system can keep up with. In 2025 alone, over 5.8 million dogs and cats entered US shelters; 597,000 of them didn't make it out alive. (1)

Although some of those animals were too sick or injured to save or displayed behaviors that made them too dangerous to safely place, many of the animals who were euthanized were happy, healthy, behaviorally-sound animals who could have made excellent family companions. They lost their lives because there wasn't enough space for them, aren't enough resources in our underfunded animal welfare system, and aren't enough homes willing and able to adopt. (2)

Shelters are not equipped to care for young animals or nursing moms

Giving birth or caring for young babies in a shelter environment can lead to longterm health and behavior consequences for both mom and babies.  

Pregnancy can be extremely taxing for a dog or cat, especially when that animals is particularly young, old, or undernourished - all of which are common scenarios for unplanned pregnancies. (4, 5) Puppies and kittens born to mothers who have not received adequate care throughout their pregnancy are more likely to develop health and behavioral issues throughout their life. (6) There is evidence to suggest that when a mother dog or cat is particularly stressed during pregnancy or birth, her offspring may be more likely to develop anxiety in adolescence or adulthood. Anxiety can increase the chance that a dog or cat will display undesirable and even dangerous behaviors in adulthood, which can lead to them ending up back in a shelter. (3)

Giving birth in a shelter environment poses immediate health risks from communicable diseases to both mother and offspring. (6, 7) Young families are at high risk of contracting deadly viruses and diseases like Parvo and Distemper, often brought into the shelter by other young animals or adults who are carriers, but not showing symptoms. Even viruses and diseases that are typically considered mild, like an Upper Respiratory Infection (URI), can be deadly for young families. Young families must be housed away from other animals in an area that is less likely to be infected and is safe for mom and babies to move around - something that most shelters are unable to do.

Private rescues cannot keep up with demand

Terminating pet pregnancy prevents suffering

Shelters and rescues are already overwhelmed by the number of pets in need without a dog or cat giving birth in the care of the organization. When a pregnant pet comes into their care, most organizations will choose to terminate the pregnancy.

Spay abortion is a routine procedure, performed on a daily basis in veterinary clinics across the country.

There may be some increased risk to the dog or cat when compared to a routine spay procedure, as blood vessels increase in size throughout pregnancy and can be harder to tie off, however, precautions will be taken to prevent excessive blood loss. In most cases, the risks associated with spay abortion are smaller than the risks associated with allowing the pet to carry the pregnancy to term. (4, 6, 7)

Spay abortion can be performed at any point in the pregnancy, up until the day that the dog or cat goes into labor. Recovery is comparable to that of a routine spay; most dogs and cats are ready to resume normal activity as soon as their incision heals.

Spay abortion prevents fetal suffering

During a spay abortion, the entire uterus - including the fetuses - is removed. The fetuses are under the same anesthesia as the mother; they will not gain consciousness, and therefore have no ability to perceive pain, even in late-term terminations in which the fetal respiratory movements have been observed prior to the procedure. (6, 8)

The controversy is human

Most arguments against spay abortion revolve around human emotions, not the wellbeing of animals.

Our beliefs animal care - and our ability to provide that care - are deeply intertwined with human welfare. The way that we discuss spay abortion is directly colored by our beliefs about human abortion, women's rights, and women's access to healthcare. Discussing spay abortion is taboo because discussing abortion in general is taboo. But it doesn't have to be!

Cats and dogs do not plan for pregnancy in the same ways that humans do; they aren't picking out names or painting the nursery. They do not dream of being a mother, and they do not feel like they are "missing out" if they don't become one. Most dogs and cats who enter shelters and rescues pregnant are still babies themselves; cats in particular can become pregnant as young as four months old. These young animals do not deserve to go through the physical and emotional toll of delivering and caring a litter, especially without a stable home of their own.

It’s okay to feel sad or have mixed emotions about spay abortion, but those emotions don't negate that benefit that spay abortion provides. If the goal of animal welfare is to prevent suffering, then spay abortion is integral to the mission.
