When Do Boston Terriers Go Into Heat


Dogs, like humans, go through a reproductive cycle that makes them open to mating. But have you ever questioned the heat cycle of your female Boston Terrier and what to do while she’s in heat?

Don’t worry, we have got your back. If you’re thinking about buying a female Boston Terrier or If you already own a healthy Boston Terrier female, this article is for you.

When Do Boston Terriers Go Into Heat

The heat cycle is a physical process that happens in most female dogs. The age at which a pup’s first heat cycle occurs fluctuates markedly depending on the breed. Small breeds can go into heat for the very first time as early as four months old, but large breeds can take up to two years to go through their first heat cycle.

The major question is when a Boston Terrier enters heat. A Boston Terrier hits heat between the ages of six and nine months when she is just coming into puberty and will have her first heat cycle.

How Long Do They Stay In Heat? 

The heat cycle continues typically for three weeks and results in physical and behavioral changes. However, it is dependent on several things, such as the dog’s age, fitness, and nature.

There are also a few abnormal heat cycles like split, absent, and silent heat. 

A dog’s heat cycle is regulated by several hormones which work together to produce a regular heat cycle, usually occurring every six to eight months. However, a variety of factors can disrupt the normal hormone balance and cause abnormal heat cycles. 

For example, certain medications can interfere with hormone production, while others can trigger a silent heat phase. Additionally, health conditions like tumors or ovarian cysts can also cause hormonal imbalances that lead to abnormal heat cycles. 

Ultimately, any factor that affects hormone levels can potentially disrupt a dog’s heat cycle. Suppose your dog is experiencing abnormal heat cycles. In that case, it is important to consult with a veterinarian to determine the underlying cause.

How Often Do They Do They Go Into Heat?

The majority of dogs have a heat cycle twice a year. Some breeds, especially little ones, go through three cycles each year. In contrast, large breeds may only have one cycle each year. When it comes to Boston Terriers, they go into heat twice a year, or after every 6 months, like the majority of dogs. You can say, they drive into the heating cycle every 26 to 34 weeks.

Heat Cycle Of A Female Boston Terrier

In female dogs, the heat cycle is divided into four stages:

Proestrus: it is the beginning of the heat, which lasts 5 to 20 days. The vulva of the dog swells and blood is expelled, much like a female human’s period. Your dog is also likely to go pee more. 

Females are attracted to males but are not ready to mate. They may hide from male dogs and try their best to avoid unwanted attention. They may also get more clingy and want to be around you more. 

Estrus: it is the mating time, which lasts between 3 and 21 days. The flow of blood decreases, gradually turning pinkish and yellowish, until it entirely ceases. Females will be more receptive to mating and might go wandering in search of a male. Males will be drawn to and accepted by females.

If you choose not to spay your female Boston Terrier, keep a close eye on her and be prepared to ward off unwanted attention. 

Diestrus: This is the time following the heat, which can last up to 60 days. The female dog is either pregnant or in a resting phase during this period. Boston Terriers are not responsive to male dogs since they are no longer fertile.

Anestrus: Between diestrus and the following heat cycle, there is anestrus, a resting phase. This phase prepares the Boston Terrier’s body for the upcoming cycle or pregnancy. Female dogs may not be interested in mating, but intact male dogs may still be attracted to them.

What To Expect When Your Boston Terrier Goes Into Heat? 

When your dog is in heat, one unusual thing to watch for is she might run away from home in search for a worthy mate. Keep a close watch and be sure that if you have a yard, the fence or boundary is escape-proof.

Some Boston Terriers in heat will exhibit nesting behavior and become more lethargic than normal, so give a peaceful, comfortable, and child-free environment where she can snooze whenever she needs to. 

She might also be more clingy and want to be around you more. Her appetite might swing from hungry to lackluster constantly. 

Although Boston Terriers are active and energetic dogs, don’t overdo their daily activity throughout the cycle because their energy will be low.

How To Prevent Your Dog From Going Into Heat?

There is only one way to prevent your dog from going into heat, and that is to spay her.

This simple surgery can have a profound impact on your dog’s health and wellbeing, not to mention help reduce the homeless pet population. Here are just a few reasons why you should spay your female dog:

  • Spaying helps to prevent uterine infections and cancer of the reproductive organs.
  • Unspayed dogs are more likely to roam, increasing their risk of being hit by a car or getting into fights with other animals.
  • Spaying your dog will prevent unwanted pregnancies and reduce the number of puppies being born.

Frequently Asked Questions 

Do Boston Terriers Experience Silent Heat?

You may have heard about something called a “silent heat.” Silent heats are more common in small breeds of dogs like French Bulldogs, but any dog can experience one. 

So, what is a silent heat and how does it affect dogs? A silent heat is when a dog comes into heat but doesn’t show any obvious signs. This condition, which occurs in female dogs that haven’t been spayed, is characterized by a lack of obvious symptoms such as increased urination or vocalization. 

However, that doesn’t mean that your dog isn’t in distress – on the contrary, silent heat can be just as uncomfortable for your pet as a traditional heat cycle. While most dogs will have some bleeding and will act differently when they’re in heat, dogs in silent heat may not show any external signs at all. 

However, they will still be fertile and able to get pregnant during this time.

Do Boston Terriers Experience Absent Heat?

Like many dogs, Boston Terriers can have abnormal heat cycles, one condition of which is absent heat. 

The canine equivalent of a missed period, an absent heat is when a female dog skips a heat period occasionally. Dogs are not like humans when it comes to their reproductive cycle. For dogs, heat periods or estrus cycles occur about twice a year. 

The estrus cycle is the time when a female dog can become pregnant. However, some female dogs may skip a heat period occasionally. Several reasons a dog might miss a heat period include stress, illness, or rapid weight loss. If your dog misses a heat period, it is important to take her to the vet to rule out any potential medical problems. 

Do Boston Terriers Experience Split Heat?

A split heat is a medical condition that can affect all dogs, Boston Terriers included. This condition is when an unspayed female dog goes into heat, stops and goes out of heat for a few weeks or months, and resumes her heat. 

Split heats are more common in young dogs and can be disruptive to their owners’ lives. In some cases, the dog may not show any signs of discomfort or distress. However, in other cases, the dog may exhibit symptoms such as lethargy, weight loss, and vaginal discharge. 

If you suspect that your dog is experiencing a split heat, it is important to contact your veterinarian. They will be able to perform a physical examination and order diagnostic tests to rule out any underlying medical conditions. 

Should You Spay Your Boston Terrier?

If you are not intending to breed your dog, you can most certainly consider spaying her. Spaying has numerous advantages, like lowering health risks, increasing lifespan, and preventing unwanted pregnancies as part of being a more responsible dog owner. 

There are both health and ethical reasons for spaying your dog. Spaying helps to prevent many health problems in dogs, including uterine infections, mammary tumors, and pyometra. It also reduces the risk of ovarian cancer and eliminates the heat cycle. As a result, spaying can help your dog live a longer and healthier life. 

Every year, millions of animals are euthanized because there are simply not enough homes for them all. Spaying your dog helps to reduce this problem by preventing unplanned litters. From an ethical perspective, spaying also helps to reduce the number of unwanted animals.

Some might argue that spaying changes a dog’s behavior, which is not necessarily a bad thing. The most obvious change is that, after being spayed, a dog will no longer go into heat. This can be a relief for both the dog and her owner, as heat cycles can be messy and disruptive. 

In addition, spaying can help to reduce aggression and roaming behavior. Dogs who are spayed are less likely to try to escape and find a mate. As a result, they are generally calmer and easier to train. Though there are some risks associated with spaying, the potential benefits make it a decision that is well worth considering for any dog owner.
