What is an important post-operative care instruction for pet owners following a spay surgery?

Keeping the incision site clean and dry is crucial following a spay surgery. This care instruction helps prevent infection and promotes proper healing, as the surgical site is vulnerable in the days and weeks following the procedure. An owner should monitor the incision for any signs of swelling, redness, or discharge, which could indicate an infection. By ensuring that the area remains clean and dry, the pet owner supports the healing process and minimizes complications.

The other options, while they may relate to pet care, do not address the immediate post-operative needs after spay surgery. Allowing a pet to run freely outdoors could lead to injury or strain on the surgical site. Not feeding the pet for 24 hours may not be necessary or advised in all situations, as pets usually can resume normal eating routines based on the veterinarian's recommendations. Lastly, removing stitches at home without veterinary guidance could lead to improper healing or complications, as not all sutures are meant to be taken out by the owner.
