Post-Operative Instructions

Thank you for having your pet spayed/neutered at the San Antonio Humane Society (SAHS) or the Brooks Spay/Neuter Clinic. This operation helps decrease the number of unwanted pets in our city as well as improves your pet’s chances for a longer, healthier life. We strongly recommend that you establish a relationship with a full-service veterinary clinic to ensure your pet gets continued healthcare, including vaccine boosters, deworming, and all health issues NOT directly related to this surgery.

  • Your pet may be unsteady, groggy, or sleepy tonight. This is normal after having anesthesia. Complications can occur (seromas, incision opening, swelling, bleeding) if your pet is TOO ACTIVE. All outside time (potty, walks, etc) should be kept short for the next 7 days and dogs should be leash walked only.  Cats should be kept inside for a MINIMUM of 3-5 days, 7 is ideal, if they normally go outdoors. Feral cats are the ONLY exception to this rule.

  • Introduce food slowly tonight. Offer only ¼ of your pet’s normal amount of food. If no vomiting occurs after 1 hour, you may offer another ¼ of food. Please do not allow your pet to free feed after anesthesia, as this causes vomiting.

  • A pain injection was given after your pet’s surgery that should last approximately 24 hours. We offer additional pain medication for both cats and dogs either alone or in a “Comfort Package” with an e-collar.

  • NO BATHS OR SWIMMING for 7 days. Wetness (from bathing or licking) will cause the tissue glue and sutures to dissolve and promote infection of the surgery site. Please keep the incision clean and dry. You may clean gently around the incision with warm water, pat dry with a paper towel, and apply a topical antibiotic ointment at home.

  • We HIGHLY recommend purchasing an e-collar from SAHS, your vet, or a pet supply store. The collar should extend 3 inches beyond your pet’s nose to prevent licking and fit snuggly behind your pet’s ears.  It should not be loose enough to slip off.  If you purchase an e-collar from us, we will ensure that it fits properly.   This collar should be worn at ALL TIMES for 7-10 days post-operatively.

  • Your pet’s incision should be covered with a SILVER AEROSOL SPRAY that acts as an extra protective barrier against contamination and as a first warning sign that your pet has been licking.  If you notice an absence of silver or a suspicious silver nose, this is a sign that there is an issue and your pet is accessing the area.

  • Look at the incision daily for the next 7 days. If you see more than a few drops of bright red blood, green or yellow discharge, or severe swelling or redness, please come in for a free surgery recheck. If antibiotics or additional medications are required, you are responsible for any extra charges.

  • Unless you are told otherwise, sutures are absorbable and do NOT need to be removed. If your pet did need staples or external sutures, you will be informed. Staples will need to be removed 1 week from the surgery date during recheck hours.

  • A PERMANENT GREEN TATTOO LINE was placed on your pet’s skin near the incision as a sign that your pet has been spayed/neutered, should he/she get lost. Feral cats receive a tattoo and have their left ears “tipped”.

  • One episode of vomiting or diarrhea can be normal after anesthesia. Multiple episodes of vomit/diarrhea with or without blood are NOT normal and usually NOT caused by the anesthesia. We recommend you see your regular veterinarian (or emergency clinic if after hours) for any severe episodes of vomiting and/or diarrhea.

  • The nearest ER to the shelter is Animal ER 4315 Fredericksburg Rd (210) 737-7380. We DO NOT refund ANY veterinary clinic or emergency clinic visits.
