Dog castration

What happens during the operation?

Castration is carried out under a full general anaesthetic. Due to the anaesthetic, your pet may be sleepy and a bit unsteady for the next 12-24 hours. During this time, your pet should be allowed to rest quietly in a warm (not too hot), comfortable, draught-free place and should be monitored closely.

During the operation, the veterinary surgeon will suture (stitch) the incision between the penis and the scrotum. These sutures are usually dissolvable; buried under the skin (and so cannot be seen). Sometimes we will use nylon sutures that need to be removed approximately 10 days after the procedure. 

During the operation, the Vet will have placed a breathing tube into the windpipe to help him breathe through the anaesthetic. This can sometimes cause a little irritation, your pet may have a slight cough but should not persist more than a day or so.

After care

After the operation, your dog may be tempted to lick their wound, however this can slow down healing and introduce infection. We have supplied you with a buster collar which should be worn at all times, although it can be removed for feeding. Please ensure he is supervised to ensure he does not lick or chew the wound. 

The wound should be checked on a daily basis for pain, swelling, or discharge (it is normal for the first 24hours to see a few drops of blood; if any more than this you should contact us for an appointment so we can check the wound). Check that the surgical site is healing well and there are no holes in the wound and that the sutures are holding.

Do not apply anything to the wound and the wound should not be cleaned unless advised to do so by a member Veterinary nurse or Vet.

A post op check should be booked with a Veterinary nurse 3-5 days after surgery, this is so we can check the wound is healing normally.

If external sutures are present these will be remove by the veterinary nurse between 10-14 days after surgery.


For the first 24 hours, your dog should only be allowed out to the toilet and not walked, we advised that you use the lead in the garden to prevent running around.

After the first 2 days, you can take your dog on short lead walks, this should be continued for 7-10 days.

For the first week, extra care should be taken to prevent strain on the wound, this means that ideally your dog should be lifted in and out of the car, do not allow upstairs or on the sofa. (if difficult to keep off sofa you can lift them up and down). Care should be taken not to apply pressure to the wound when lifting.

Avoid muddy areas to keep the wound as clean as possible, and do not allow swimming. Do not book into the groomers or give a bath etc. until the wound is healed.


Although your pet has been offered a small meal while in the hospital they can be offered another light meal tonight. This should be easily digestible such as cooked chicken and boiled rice or white fish. Alternatively, you can purchase a tin of Royal Canin Gastrointestinal food from reception. 

Normal appetite should return in 24-48 hours so can be offered their normal diet the day after surgery. 

Once fully recovered reduce your pet’s daily amount of food by approximately 1/4. Their metabolism will start to slow down and reducing food intake will help prevent obesity.

If your pet has not eaten within 48 hours of his operation, he is listless or unsteady, or you have any other concerns about the wound or his well-being please telephone us for advice on 01383 722818.

We operate an out of hours’ service after 7pm. If you are very worried about your pet and feel that they can’t wait until the next day for an appointment. Please call 01383 722818 to arrange an emergency appointment.
