When Does a Chihuahua First Come Into Heat?

Most female Chihuahuas come into heat for the first time between the ages of 5 and 9 months. However, it can also take up to the completion of the first year of life.

However, many owners do not really notice the first heat. The symptoms are ambiguous or there are even no signs at all. This phenomenon is called silent heat or white heat. This requires special caution and observation skills from the owner. Because the bitch can also be covered by a male in the quiet heat.

Tip: Make a note of the start of your first heat. For example, when you noticed the first drops of blood. In this way, subsequent heat events can be better predicted.
