What happens when the dog is in heat

The heat occurs during estrous, the phase of a dog’s reproductive cycle when the female dog produces eggs that are ready to be fertilized. A dog in heat will show certain physical and behavioral changes that indicate that the female dog is ready to mate. Males can pick up these hormonal signals, and the female dog will be receptive to their advances.

When does Labradoodle go into heat?

For the first time, Labradoodles begin a heat cycle when they reach puberty, usually at the age of about 9 months. However, in some cases, they can begin at the age of 12 to 15 months.
