What to Do Before and After Your Pet's Spay or Neuter Surgery
Prepare your pet and your home before surgery day
The week before surgery, schedule a pre-operative exam with your veterinarian if you haven't had one recently. This visit checks that your pet is healthy enough for anesthesia and catches any problems — like a heart murmur or infection — that could complicate the procedure. Bring any medical records from previous vets, especially if your pet has had reactions to medications or anesthesia in the past.
Stop feeding your pet the night before surgery. Most vets require a fasting period of 6 to 8 hours before the procedure because food in the stomach during anesthesia can cause vomiting and aspiration. Ask your vet whether to give water that morning — some allow small amounts, others do not. Write down the exact fasting instructions and the time you need to arrive.
Prepare a quiet recovery space at home before surgery day. This should be a room where your pet can rest without jumping, running, or playing — a bedroom or bathroom works well. Set up food and water bowls, a litter box (for cats), and bedding in this space. Keep the area cool and dim, away from other pets and children who might disturb your recovering animal.
Key Takeaways
- Your vet will give you written post-operative instructions; follow them exactly, including activity restrictions and medication schedules, because complications often come from pets moving too much too soon.
- Most pets go home the same day as surgery with pain medication and a cone or surgical suit to prevent licking the incision.
- Watch the incision daily for swelling, discharge, or opening; contact your vet immediately if you see any of these signs.
- Keep your pet calm and confined for 10 to 14 days after surgery — no running, jumping, or rough play, even if your pet seems to feel fine.
- Arrange for someone to be home the first night after surgery, because some pets have reactions to anesthesia or pain medication.
Understand what happens on surgery day
Arrive at the clinic at the time your vet specified. Bring your pet's medical records, a list of any medications your pet takes, and your contact information. The vet will do a final health check and have you sign a consent form that describes the procedure and any risks. Ask questions now if anything is unclear — this is your last chance before your pet goes back.
Your pet will receive pre-operative medication to calm them, then anesthesia. The actual spay or neuter surgery takes 20 to 90 minutes depending on your pet's age, size, and whether there are complications. Your vet will call you with an update while your pet is in recovery. Most pets wake up within a few hours and go home the same day, though some clinics keep pets overnight for observation.
When you pick up your pet, the vet will give you written post-operative instructions, pain medication, and sometimes an antibiotic. Read these instructions carefully before you leave — do not rely on remembering what the vet said. Ask the vet to show you how to give any medications and what side effects to watch for. Take a photo of the written instructions with your phone so you have them if questions come up later.
Manage pain and prevent licking for the first two weeks
Your vet will send pain medication home with your pet — usually tablets or liquid given by mouth for 5 to 10 days. Give the medication exactly as directed, even if your pet seems comfortable. Pain medication helps your pet rest, and rest helps the incision heal. Do not skip doses or stop early because you think your pet feels better.
Your pet will wear either a cone (also called an Elizabethan collar) or a surgical suit to prevent licking or chewing the incision. A cone is the most common option and the most effective, though many pets dislike it. A surgical suit is less annoying but requires a better fit to work. Some pets will still find ways to lick around either barrier, so check the incision several times a day. If your pet is licking despite the barrier, contact your vet — they may recommend a different style or a bandage over the incision.
Keep the incision dry and clean. Do not bathe your pet or let them swim for at least 10 days after surgery, or until your vet says the incision is fully closed. If the incision gets wet or dirty, gently clean it with a soft cloth and lukewarm water, then pat it dry. Do not use soap, hydrogen peroxide, or antibiotic ointment unless your vet tells you to.
Watch for signs of infection or complications
Check the incision every day for redness, swelling, discharge, or opening. A small amount of mild swelling and slight redness right around the stitches is normal for the first few days. Increasing swelling, pus, blood, or an opening in the incision is not normal — contact your vet the same day if you see any of these.
Watch your pet's behavior and appetite. Some grogginess and reduced appetite for the first day or two after surgery is normal as the anesthesia wears off. If your pet is not eating or drinking by the second day, is vomiting, has diarrhea, or seems unusually painful or lethargic, call your vet. These can be signs of a reaction to anesthesia, infection, or other complications.
Some pets develop a seroma — a fluid-filled swelling under the incision — in the weeks after surgery. This usually goes away on its own but can become infected. If you notice a soft, squishy lump near the incision that grows or becomes hot to the touch, contact your vet.
Keep your pet calm and confined during recovery
Restrict your pet's activity for 10 to 14 days after surgery. This means no running, jumping, playing, or rough housing — even if your pet seems to have lots of energy. Activity can tear open the incision or cause internal bleeding, and these complications may not show up for several days. Keep your pet in the quiet recovery space you prepared, or supervise them closely in a small area of your home.
Do not take your pet outside except to go to the bathroom on a leash. No off-leash play, no trips to the dog park, no climbing stairs if possible. Cats should be kept indoors and away from other cats. If you have multiple pets, separate them during recovery so your healing pet is not chased or roughhoused.
Short, gentle walks on a leash are fine for dogs if your vet approves, but these should be slow and brief — just long enough to go to the bathroom. Ask your vet when it is safe to return to normal activity. Most pets can resume normal exercise after 10 to 14 days, but some need longer depending on their age and the vet's assessment.
Plan for the follow-up visit and suture removal
Your vet will schedule a follow-up exam 10 to 14 days after surgery to check that the incision is healing well and remove stitches or staples if they are not dissolving on their own. Mark this appointment on your calendar and do not miss it — your vet needs to confirm the incision is closed before you can return your pet to normal activity.
At the follow-up visit, tell your vet about anything unusual you noticed — any discharge, swelling, or behavior changes. Bring your pet's pain medication bottle so the vet can see how much was used. If your pet still seems to be in pain or the incision does not look healed, the vet may prescribe more medication or recommend a longer recovery period.
Manage costs and arrange time off work
Spay and neuter surgery costs vary widely depending on your vet, your pet's age and size, and whether there are complications. Ask for a full estimate before surgery, including the procedure, pre-operative exam, anesthesia, pain medication, and any other fees. Some vets offer payment plans or discounts for low-income pet owners — ask whether these are available.
Arrange to be home the first night after surgery if possible. Some pets have reactions to anesthesia or pain medication, and you need to be there to watch for vomiting, difficulty breathing, or extreme restlessness. If you cannot be home, ask a trusted friend or family member to check on your pet several times that evening.
Plan to take time off work or school for the follow-up visit 10 to 14 days after surgery. This appointment usually takes 30 minutes to an hour. If you cannot make it during business hours, ask whether your vet has evening or weekend hours, or whether another vet in the clinic can do the follow-up exam.
Frequently Asked Questions
Can my pet eat or drink right after coming home from surgery?
Wait at least 2 to 4 hours after arriving home before offering food or water. Start with small amounts — a few tablespoons of water, then a small meal — because pets sometimes vomit after anesthesia. If your pet vomits, wait another hour before trying again. Your vet's discharge instructions will specify timing for your pet.
What if my pet's stitches open or the incision starts bleeding?
Contact your vet immediately, even if it is after hours. If the incision is actively bleeding heavily, apply gentle pressure with a clean cloth and call the emergency clinic. Do not try to clean or bandage it yourself. An open incision can lead to infection or internal bleeding and needs professional care right away.
How long does it take for the incision to fully heal?
The outer layer of skin closes within 10 to 14 days, which is why stitches are removed around that time. Full internal healing takes 4 to 6 weeks. Even though the incision looks closed, the tissue underneath is still fragile, so continue to restrict activity and keep the area clean until your vet says it is fully healed.
Can I use a heating pad or ice pack on the incision?
Do not apply heat or ice directly to the incision. These can damage the healing tissue or cause swelling. If your pet seems to be in pain beyond what pain medication helps, contact your vet — this can be a sign of infection or another complication.
What should I do if my pet will not stop licking the incision?
Try a different style of cone or surgical suit — some pets tolerate one better than the other. You can also try a soft recovery collar or a t-shirt to cover the incision. If your pet is still licking despite barriers, contact your vet. Excessive licking can introduce bacteria and cause infection, so your vet may recommend additional steps or medication.
