De-sexing/Dog Castration Post-Op-Care instructions

We just wanted to provide a little information regarding the needs of your pet after desexing surgery.

We do like to take a few extra precautions to ensure comfort, safety, and smooth recovery from your pet’s surgery. 

  • Pre-op pain relief, sedation and calming medication.

  • Intravenous fluid therapy throughout,

(You will notice a small area on their front leg shaved, this is where the intravenous catheter was placed)

  • Heated surgical wards and warm air mattress throughout surgery

  • A dedicated Theatre nurse

  • Constant monitoring of Heart rate, Respiratory rate, blood pressure, oxygen levels and temperature.

Whilst most patients are back to normal very quickly, with little visible discomfort, there are a few pets who may have some increased irritation post-op, particularly given the sensitive area.

Unfortunately Dogs do not always understand that they must rest and leave their wound alone, so we need your to assist us with Marni’s recovery.

Pain relief

Two types of pain relief have been given today, both before and after surgery. Additional pain relief will also be provided to take home,  ensuring your pet remains as comfortable as possible.

The additional pain relief can generally be started tomorrow as directed. Watch for any tummy upsets such as vomiting or diarrhea and call if any signs develop.

If you feel that  you pet is in any great discomfort, distress or pain please let us know.

Immediately After

It is quite normal for some pets to be a little sleepy when the return home.

  • Tonight, please keep your pet indoors in a quiet, warm place

  • Offer a smaller meal for dinner instead of a large one

  • You should be able to feed as normal from tomorrow

The Surgery Site

There can be a small amount of swelling around the surgery site. For some dogs with extremely sensitive skin, there can be increased redness and irritation as well. The additional pain relief provided will also work as an anti-inflammatory to help reduce any inflammation and discomfort. Sometimes a soothing skin cream can help, and may be provided if needed.

In a few pets, particularly small breeds, they may seem unsettled and reluctant to walk without sitting down all the time. This can be caused by irritation from the stitches. If this is the case we can certainly provide a little added help to help calm and reduce any increase pain or discomfort.

Please call to let us know if you are worried about your pet.

Home care over the next 10 days

We expect that they should be close to their normal self tomorrow. Unfortunately this does have some disadvantages in that they may want to start jumping, running around too soon. Please try to keep them quiet for the first 5 days, as too much activity can lead to further irritation of the wound and stitches.

Wound Care: Please ensure they are not licking the wound. If not already provided an Elizabethan collar is recommended to stop licking and wound trauma, avoiding complications.

Licking: Licking of the sutures/wounds needs to be avoided to reduce wound irritation and the risk of infection. An Elizabethan collar will be needed to stop licking if this is the case and is recommended for all pets during the the post op period..

Activity: Try to minimize jumping and running as this can lead to swelling and bruising, and added discomfort.

Short lead walks can begin within 2-3 days after surgery. Off-lead and running is not recommended.

Avoid heavy exercise until the stitches are removed at 10-14 days post-op


If Non dissolvable skin stitches have been used, sutures will need to be taken out in 10-14 days, so please arrange time with one of our nurses to have this done.

If dissolving stitches have been used, further instructions will be given for and a post-op check organized if needed.

Things to watch for

Generally there are very few complications after the operation, however, there are some signs to watch for that may indicate a problem.

  1. Dull and listless (especially after the first 24 hours)

  2. Excessive redness, irritated or Swelling around the wound.

If you notice any of these signs please do not hesitate to call our clinic.

If you have any concerns or questions please don’t hesitate to call.
