Yes. You can spay a pregnant dog or a pregnant cat. We still schedule the surgery when she passes the morning exam.
Yes, you can spay a pregnant dog or a pregnant cat. The surgery removes the ovaries and uterus, which ends the pregnancy. I still do this at The Pet Advocate when she passes the morning exam. The surgery takes more time than a routine spay.
Rescue groups and people who trap community cats bring pregnant cats in to stop the next litter. We take those cases. VIN Veterinary Partner describes the same operation: the uterus comes out with the ovaries.
In a pregnant dog or cat, the uterus is larger. The vessels that feed it are wider and take more care to tie off. The incision has to be long enough to lift that tissue out safely, so closure takes longer and she stays under anesthesia longer. Most hospitals charge more and take longer. The scar is longer too. VIN describes that extra work.
We confirm the extra fee at booking or exam. The prices and rates page notes that extra fees apply for pregnant dogs and cats. The extra fee isn't one posted number. It depends on how large the uterus is.
Nesting or a little milk afterward can still happen. It doesn't mean she is still pregnant.
The added risk is bleeding and extra time under anesthesia. Recovery still follows the same 10-day activity limit and 14-day cone we use for other spays.
People often hear that it's kinder to let a pregnant dog or cat deliver, raise the litter, and book the spay after weaning.
We can't schedule a female who is nursing, who is lactating on surgery day, or who has given birth in the past four months. Pregnancy already took about nine weeks. Nursing uses several more. The four-month wait starts after birth, so the next date we can offer is months away.
She can also get pregnant again while she is still nursing.
The ASPCA has written about owned pets that get stuck in labor. A young or already-stressed female can run into that trouble.
If the plan is to have this litter and fix her after, read the four-month rule on the surgery requirements page before you pick a date.
A prior C-section or other abdominal surgery can still stop the appointment. Very late pregnancy can change the plan. She still has to pass the exam that morning.
We don't publish a week-by-week cutoff. The veterinarian decides from what is in front of them, not from a week number on a chart. Age, weight, breed, and health screens still apply. Check the surgery requirements page before you drive.
Tell the team she may be pregnant when you book. Don't wait to see how far along she is unless a veterinarian has already told you the pregnancy is too far along for this clinic.
A cat spay is $130. A dog spay is $200, $240, $280, or $350 by weight, with a 100-pound cutoff. A $20 deposit holds the appointment and comes off the total. Pain tablets and a cone are optional.
Drop-off is by appointment, Monday through Friday. Same-day pickup is the plan.
Book through schedule your appointment or start on the low-cost spay and neuter page.
We take out the ovaries and uterus. We don't leave her able to breed later.
Yes. Removing the uterus and ovaries ends the current pregnancy.
Early and mid pregnancy are routine when she passes the exam. Late pregnancy is decided on exam. We don't publish a week cutoff. If she is close to delivering, say so when you book.
Not until four months after birth, and not while she is nursing or lactating.
She might leak milk or nest after a pregnant spay. Watch the incision and keep the cone on. Call if the glands look painful, hot, or are draining pus.
No. During heat the vessels swell. Pregnancy adds a larger uterus. Heat-only cases belong on Can You Spay a Dog in Heat.
Pregnant community cats can still be spayed. The process and hold times are on feral cat spay and neuter.
If a pregnant dog or cat is otherwise healthy, book the spay. If she already delivered, check eligibility before you pick a date. Call (209) 879-9367 if you want a person to hear the history first.
