How should I care for my pet after spay or neuter surgery?

The first days after surgery focus on pain control, preventing licking, limiting activity, monitoring the incision, and following the individual discharge instructions from the surgical team.

The key takeaway

Your clinic’s discharge instructions take priority because surgical technique, age, medications, and individual risk vary.

The first evening

Mild sleepiness after anesthesia can be expected. Offer food and water according to the clinic’s instructions, often in smaller amounts initially. Contact the clinic if your pet is difficult to wake, repeatedly vomits, has trouble breathing, or seems progressively weaker rather than more alert.

Protect the incision

Check the incision at least daily. Mild bruising or small amounts of swelling can occur, but increasing redness, heat, discharge, bleeding, gaping, or marked swelling is abnormal. Prevent licking with the recommended recovery collar or garment.

Activity restriction matters

Running, jumping, rough play, and off-leash activity can stress internal and external sutures. Follow the prescribed restriction period even if your pet seems energetic after a day or two.

Medication safety

Give only medications prescribed or approved by the veterinarian. Human pain medications such as ibuprofen or acetaminophen can be dangerous to pets. Do not stop prescribed pain control early because the animal appears quiet.

Call the surgical team for persistent bleeding, a rapidly enlarging swelling, incision opening, repeated vomiting, severe pain, pale gums, collapse, difficulty breathing, or inability to urinate.
