When Do Female Goldendoodles Go into Heat?

A female Goldendoodle usually first goes into heat when she’s six months old. This is when she is usually sexually mature, and enters the heat cycle.

During this cycle, your female Goldendoodle goes through some stages, and each stage is linked to some hormonal and physical changes. The heat cycle of dogs is surprisingly somewhat similar to periods or menstruation cycles in humans. 

Your Goldendoodle will have four stages that she will go through. That is part of their heat cycle. 

The four main stages of a Female Goldendoodles heat cycle

– The total length of a dog’s heat cycle is 18-21 days.


The first stage of a heat cycle in dogs is proestrus, and this is when you can notice your dog is in heat. Normally, this stage lasts for an average of 9 days but can range anywhere from 0 to 27 days. It is when male dogs are attracted towards your female Goldendoodle, but she is not receptive at that time.


Next up, is the estrus stage, and it is the main stage of the heat cycle deciding whether female Goldendoodle will be expecting or not. Your Goldendoodle will be more receptive to male dogs, so better watch her closely if you don’t want her pregnant. Typically, the estrus stage lasts between 5 to 9 days, and she discharges less blood.


The third stage is diestrus that starts on day 24, and during this stage, your Goldendoodle is no more receptive to males.


During anestrus, the last stage of the heat cycle, your Goldendoodle starts returning to normal. There will be no discharge from the body or any abnormal thing. The anestrus phase can last from 60 to 90 days, and as soon as she is done, her heat cycle will start again.

How Often Do Goldendoodles Go into Heat?

Goldendoodles on average go into heat twice a year

This is approximately once every six months and each period lasts between two weeks and a month. However, if your Goldendoodle is more like her poodle parent, she can experience heat once every four months.

The heat time depends on a dogs breed. The smaller the dog breed, the more often your female dog will go into heat. 

When Do Mini Goldendoodles Go Into Heat?

As well as, due to their smaller size, their heat cycle can happen as often as every four months.

How To Know If My Female Goldendoodle Is In Heat?

There are seven common signs when it comes to understanding if your female Goldendoodle is in her heat cycle.

Seven signs include:

  1. Swollen vulva.
  2. Bloody or straw-colored discharge from the vulva.
  3. Receptive to male dogs.
  4. Excessive licking of the genital area.
  5. Agitated, nervous, or aggressive behavior.
  6. Urinating more frequently.
  7. Change in tail position.

If your Goldendoodle has any of these symptoms and has past the age of six months. She’s most likely experiencing her heat cycle.

How to Take Care of your Goldendoodle When She’s In Heat?

Taking care of dogs in heat is necessary because they are in emotional and hormonal stress, and your affection can soothe them.

Give extra support and attention to your female Goldendoodle during her heat cycle. Give hugs, and cuddle to let her know that you are there for her and by her side.

A great tip is to provide chew toys to help with any pain or discomfort. You can also keep her engaged by playing fetch, tug-of-war, hide and seek, or even offering treats. Anything to distract her from what’s going on will help the situation.

When your Goldendoodle is in the last stage of heat (Anestrus), don’t let her go outside alone and keep an eye on her even if you are there to prevent any male dogs from coming closer. This is because she may get aggressive with them in some phases. Plus, it is better to keep them away if you don’t want her pregnant.

Make sure to give her a balanced, healthy diet, rest, and exercise. At the same time, give her a comfortable spot to relax without any disturbance.
