The best age for sterilizing your female dog


Today we will talk about the best age for sterilizing your female dog?. We previously recommend ask the following questions:

Do you have a dog at home and do not plan to increase the family with more puppies? Have you considered whether to sterilize it or not?

The veterinarians tell us that spaying / neutering their dogs not only prevents overpopulation but also has some health benefits. This process reduces the risk of some types of cancer and pyometra (or infection of the uterus). In addition to that, sterilization also improves some behavioral problems such as fumigation, roaming, and aggression. Then, the next time you feel bad about spaying / neutering your dog, think about these health / behavioral benefits.

The sterilization is to cancel fertility, there are different methods to achieve it. One example is drugs, but one of the most common methods is surgery, one of the most frequent surgical interventions in the day-to-day of the veterinary clinic.

It is a safe and very common intervention in veterinary clinics, and also recovery is very fast. During this procedure, the most common is to surgically remove the ovaries and uterus, making a small incision in the abdomen. This process is called ovary hysterectomy and is performed under general anesthesia so that the animal does not suffer any pain. Once the operation is done, it is normal for your dog to be able to return home that same day. You will have to watch her and follow some special care during her recovery, following the advice was given by the veterinarian.

As you see, this intervention involves few risks a priori and many advantages. However, the development of the intervention and the benefits derived from it will depend on the age of your dog, as well as your health status, so your veterinarian will always be the one who will advise you on the pros and cons of the same.

Today, there are new sterilization techniques that are increasingly being established in more veterinary clinics: laparoscopic sterilization. It is a much less invasive surgical intervention and therefore allows better recovery of your dog.

When to sterilize a dog: dangers of not doing it in time

Each dog is unique and there are even recommendations according to the size type to carry out the sterilization. The same happens with the pathologies that may appear if they are not sterilized.

One of the most important factors that influence to identify the ideal age is the size.
Small-sized dogs should be sterilized before their first heat (7-9 months) or right after it. In this way, future breast tumors and other ailments can be avoided.

But if it is of a larger breed it is advisable to do the sterilization after its first year of life, since the process of its development and growth should not be interrupted.

In addition to these recommendations, it is also possible to practice sterilization in females over eight years old. But it is not advisable to wait so long, because at that age the castration does not prevent in the same way or not as effective as if it were done when the dog is still young. Breast and reproductive tract tumors, ovarian cysts, endometritis, and endometriosis or unwanted pregnancy are more likely if the intervention is not done in time. For that reason, after eight years it would be necessary to assess whether it is worth it or not. As always, we recommend talking to your veterinarian before making a decision.


The first and most important is that you will avoid having unwanted dogs, and the consequent problem of having to place the puppies, which often end up dead or abandoned, or go on to saturate even more protective institutions and animal shelters. Casting a dog fundamentally helps to avoid "carelessness during heat", and the consequent canine overpopulation and dog abandonment.
