When do labrador retrievers come into season for the first time?

Labrador Retrievers typically come into season for the first time between six months to one year of age, although this can vary based on the individual dog and its environment. The first heat cycle may occur earlier in smaller breeds and later in larger ones. Once they come into season, females will generally experience heat cycles every six to eight months. It's important for pet owners to monitor their dog's health and behavior during this time.
