Smaller breeds tend to heat for the first time around the age of six months, while larger dogs can be two years old before warming up.

From the age of about six months to the rest of her life, a female dog will experience oestrus or heat about every six months.

Bleeding is a natural part of a dog’s reproductive cycle but occurs on average only twice a year.

The time at which this bleeding occurs is called the heat or season of a dog.

Together with bloody discharge, these symptoms tell you that your girl has entered the season.

While your girl is in her fertile phase, bleeding may stop or become more watery.

Although you would expect the main sign to bleed profusely, it is not always clear.

Sometimes you only see small markings on the floor or in the dog’s bed.

Healthy puppy after medical exam  how long does a female dog stay in heatNowadays so many female dogs are already sterilized when people adopt them, it is not uncommon for people to get confused about the heat of a dog.

The medical term for a dog that is in the heat is in estrus. Female puppies usually experience a first destroyed somewhere between six and twelve months old. In addition to the oestrus phase, there is an entire cycle that you must understand to keep your dog healthy.

The 4 Phases Of The Canine Estrus Cycle:

Proestrus: duration 7-12 days.

In this early phase, you will see an enlarged vulva and possibly bloody vaginal discharge. It is during this phase that a female dog begins to attract male dogs. However, this is not the time to breed. Although they allow men to approach, women do not stand for mating during proestrus.

Estrus: Duration 7-9 Days.

Estrus is the fertile period. Vaginal secretion changes from bloody to straw-colored and vulvar swelling is still present. Females will stand for mating at this stage.

Diestrus: Duration Around 65-90 Days.

Characterized by discontinuation of vaginal discharge and unwillingness to mate. This is the moment when puppies start to form when mating has taken place. If you are pregnant, diestrus will last the gestation period – 63-65 days. If the female dog is not pregnant, the duration of the diestrus is 75-90 days. There are no outward signs of diestrus in non-pregnant dogs.

Anestrus: Duration From The End Of The Diestrus To The Start Of The Next Proestrus Phase.

Anestrus is the resting time for the reproductive tract. The dog will look and behave once during anestrus.

If you plan to breed your female puppy, it is advisable to wait until she is about two years old. This allows her body to become physically mature before being asked to undergo the stress of pregnancy and childbirth.

Males can be extremely persistent when they smell a bitch in estrus. For this reason, you must always keep a close eye on your puppy. If you leave her alone or somewhere near an intact dog, you run the risk of unwanted early pregnancy.

How Can I Prevent My Dog From Going Into The Heat?

Affectionate mature woman embracing pet dog in nature  how long does a female dog stay in heatIt is highly recommended to neuter your female dog, not only to prevent oestrus and unintended pregnancy but to protect it against breast cancer and reproductive system disorders.

Why Should I Neuter My Dog?

Apart from the toll your dog takes to give birth to a litter and raise puppies, the number of homeless animals euthanized each year makes an irresponsible decision to have your dog mated. (This does not apply to those who are active in sporting events for dogs and are well informed about the care of pregnant and breastfeeding puppies.) Although many people have heard that it is a health benefit to give a dog a nest before it is neutered, this belief is not substantiated.

The hardships of giving birth and raising puppies can even lead to premature aging and, in some cases, death. It has also been shown that dogs neutered before their first heat cycle have a much lower risk of developing mammary gland tumors.

When Should I Neuter My Dog?

The right time to castrate your dog is halfway between cycles, once it is mature and when you are fully aware of (and thought about) the risks and benefits of castration.

We know much more about the effects of castration on dogs than ever before.

There are many health benefits to neutering your dog. Castrated dogs, for example, have a considerably lower risk of breast cancer.

However, we now know that sterilization is not always in the interest of every dog.

That is why you have to weigh up the pros and cons that depend on your individual situation.

Your puppy can be sterilized from 2 months. It is best to consult a veterinarian to determine the best time for your girl.

How Do You Take Care Of Your Dog At Home During The Season?

She is expected to behave normally.

That said, she may need extra toilet breaks because she wants to pee more often.

It is undoubtedly important to keep your dog out of the reach of good furniture.

However, she should not feel that she is being punished for doing something wrong. Make sure she still gets the quality time she deserves.

Hygiene And Cleaning When A Dog Is Hot

It is important to clean up your girl when she is in the heat. Both for general and hygienic reasons.

If you have easily wiped floors in all rooms where your dog has warm access, it is easiest to increase your cleaning routine.

They help prevent stains on your carpets and furniture and ensure that your dog has access to all parts of your house as usual.

Some dogs in heat do not tolerate hygiene pants and will tear them off. In that case, you may want to consider a system of barriers.


Your female dog will be fertile all her life, provided she has no health issues affecting her reproductive system.

To prevent unwanted pregnancies, oestrus women must be closely monitored and kept on a leash.
