Spaying your dog or cat

Have your dog or cat professionally spayed by our vet to prevent your pet from having unwanted litter. Spaying also has positive effects on your pet's health and behaviour. It reduces the risk of your dog or cat contracting a serious, sometimes fatal disease such as uterus infection or a tumour. In addition, animals also become calmer and easier to handle after spaying. For more information about spaying, call us or make an appointment via 070 - 366 07 01.

Cost of spaying

The prices of spaying vary from animal to animal and depend on weight, among other things. For a cost indication please contact us by calling: 070 - 366 07 01.

Advantages and disadvantages of spaying

In addition to the benefits of spaying, it is important that you are aware of the risks associated with the treatment. Below we list the pros and cons.


  • A calmer and more pleasant pet
  • No blood loss
  • Easier to interact with other people and animals
  • Reduced risk of often fatal diseases, such as uterine inflammation and mammary gland tumours
  • Preventing unwanted litters


  • Metabolism slows down, increasing the risk of obesity
  • Chance that the coat changes, such as hair loss or stiffer hair
  • Chance of incontinence

In general, the disadvantages are easy to treat: with the right food you prevent your pet from gaining weight and incontinence is easy to deal with through medication.

When do I spay my pet?

We advise to have your dog or cat spayed when the animal is six to nine months old. Spaying at an early age reduces the risk of, for example, milk gland tumours.

In addition, we recommend spaying before or after heat, because the blood flow in the ovaries and uterus is then low. This means a smaller chance of complications and therefore a successful treatment.

The procedure

Spaying a dog or cat:

  • You bring your pet to our clinic sober. Before the operation we will examine the health, such as pre-anaesthetic blood tests and the heart function with the ECG.
  • We will administer the necessary anaesthetic based on the blood test values, age, breed and previous anaesthetic experiences with your pet.
  • The vet will then remove the ovaries by making a small hole in the abdominal wall.
  • During the operation your animal will be continuously monitored by our expert paraveterinarians using an ECG device, a respirator and the capnograph.
  • After the operation, your animal will sleep under a heat lamp in our recovery room.
  • When your animal has recovered sufficiently, we will call you to pick him/her up. We will give you instructions on aftercare and medication.


After surgery it is important to be vigilant about your animal not scratching or licking the wound. This can lead to an irritated and eventually inflamed wound. If your animal cannot stay away from the wound, we advise you to put on a shirt or collar.

It is important that you do not feed your animal on the day of surgery, or only in small quantities. On the following day, your animal should eat normal amounts again. If your animal does not want to eat (and drink) the day after surgery, measure the temperature and keep an eye on it. Normally the body temperature is between 38.5 and 39 degrees Celsius. Please contact us if the temperature is higher or lower.

In addition, we recommend to keep your animal inside for at least a week and to prevent too much exercise, so the wound can heal properly.

What is the difference between spaying and neutering?

Both spaying and neutering make the animal infertile. In a castration or neutering, the ovaries or testicles are completely removed. The term neutering or castration is usually used in males, where the term spaying is used for females. In rabbits the ovaries are not removed during spaying. We leave the ovaries in place and disconnect the fallopian tubes, since removing the ovaries can cause complications.

Removing ovaries or testicles has an influence on hormones and metabolism. This often results in an increase in body weight and sometimes a change in behaviour.
