How often do golden doodles go into heat?

Female Goldendoodles typically go into heat twice a year, although this can vary among individual dogs. Each heat cycle usually lasts about 2 to 4 weeks. During this time, it's important to monitor them closely, as they may exhibit behavioral changes and are capable of becoming pregnant. If you have a male Goldendoodle, it's advisable to keep them separated from a female in heat to prevent unintended mating.
