Your Golden Retriever will go into heat twice a year. It’s important to know pregnancy doesn’t affect her cycle. She will be ready to mate when the puppies are 4 or 5 months old. You may need to watch her closely to avoid litters of puppies and unwanted vet expenses.

You can buy some dog pants or diapers to prevent her from mating when she goes into heat. While the pants are not 100% full proof, they are excellent deterrents.

Another option is to lock away your best friend from potential suitors. Do this the day you spot some bleeding. Three weeks of lockdown are enough to pass the fertile period. If you have to go to public places with her, be sure not to let the dog out of your sight.

If you’ve already had enough puppies, you can consider a spray surgery to remove ovaries and uterus to prevent her from getting pregnant ever again.

How long are golden retrievers in the heat?

The heat cycle of Golden Retrievers can last anywhere between 2 and 4 weeks. The dogs go through 4 stages during their heat cycle – proestrus, estrus, diestrus, and anestrus.

In the following section, we walk you through the phases, highlighting every important detail you need to know.

First Phase – Proestrus

On average, the beginning stage of the heat cycle lasts 7 to 10 days. Generally, the dogs can undergo proestrus for about 4 to 20 days. During this phase, you’ll notice some behavioral and physical changes in your dog.

She will have a swollen vulva, which is approximately 3 to 4 times larger than its normal size.

Also, the dog will have bloody discharge but she will try licking her genital area. The pheromones she produces will attract male dogs even from a mile away. However, she’ll not be interested in mating. She may appear aggressive if male dogs try to mount her.

Second Phase – Estrus

This is a fertile period and it can last from 5 to 14 days, depending on the dog. At this stage, she will become receptive to male dogs. Often than not, your dog will move her tail to side as a way of enticing the male dog for mating. If you pay attention to her discharge, you’ll notice that it has changed from red to straw-colored.

Third Phase – Diestrus

Diestrus generally starts around day 24 and it can last for about 60 to 90 days. Your Golden Retriever cannot get pregnant during this period. The male dogs will be attracted to her scent but she may become more aggressive toward them if they attempt to mount her. The color of her discharge will change back to red and then the discharge will stop.

Fourth Phase – Anestrus

The estrogen levels return to normalcy at this stage, which typically lasts for about 4 to 5 months. The vulva also returns to normal size. Once this phase ends, it ushers in the first phase (proestrus). Well, the cycle will keep on repeating itself.

Final words

The more you become aware of your Golden Retriever, the more prepared you will be for her changes and care when she goes into heat. Although rare, some of the dogs can still begin a heat cycle, end it prematurely, and get into heat again after about two months. Your pet may experience this split-cycle during the first or second cycle before she can have well-established regular patterns. So, this should not be a reason for concern.

Nevertheless, if your dog has regular cycles and suddenly misses a cycle or two, the best course of action is to talk to a vet. Things like nutritional deficiency and stress can easily make her heat cycle to delay. But it’s good to be sure of the exact cause of the sudden change.

There you have it!
