Like the rest of mammals, dogs also go through their time of heat and it is normal that if we have never had one we do not know what we should do in these occasions.


Important Things

The first thing we need to know is that, approximately, they can have their first heat between 6 and 10 months – everything will depend on the size and / or the breed of the dog; the little ones tend to be more precocious. Knowing how to identify the first heat is very easy; we will see that it produces a little bleeding and the vulva will be more marked and pink. In addition to these physical appreciations we will see some changes, such as:

  • Behaviour change due to hormones, which may be more evident or less depending on the dog. Some are more affectionate and need more affection, others become unrulier or even a little aggressive …
  • At the time of the ride we will see an increase in the activity of our dog (to attract the attention of other males) as well as an increase in their urination.
  • Sometimes a psychological pregnancy can occur a few weeks after passing the heat.

What should we do?

 As we mentioned above, during the heat there is a slight bleeding, so we must use some absorption method so that it does not stain the whole house. For this we can use special clothes for them that can be find in the market -similar to diapers-, or use something we have at home as panties or underpants. Regardless of what we use, we will change the garment several times a day to ensure hygiene. Some people choose not to put anything and leave the dog in a closed place, this is something that we advise against because we can stress it and that will generate strong barking and nervousness.

As for the walks, they should be equally frequent; We will always be tied to our dog, we will prevent other males from approaching and trying to mount it, and we will try not to go to places where there are many dogs.


When you do not want to raise the dog it is advisable to sterilize it. Why? Well, because this way we will avoid that our pet goes through this process that can end up being quite annoying, and also, we can help to reduce the risk of suffering from breast cancer and other types of diseases in the future.
