How does a female Yorkshire Terrier go into heat?

Decorative babies grow up completely unnoticed by their owners. However, the onset of estrus indicates puberty in the Yorkshire Terrier bitch. These periods may be accompanied by exacerbations; every owner should know how to alleviate this condition and in what situations it is necessary to contact a veterinarian.

From the article you will learn: at what age should estrus begin, what is the frequency, which symptoms are considered normal and which are alarming, how to care for a female dog and when it is possible to carry out the first mating.

Signs of the onset of the first heat

First of all, let's find out what this physiological condition is in a bitch. Estrus is a prolonged sexual arousal that is caused by ovulation (the egg is ready for fertilization). For the first time, a physiological condition occurs in a Yorkshire terrier bitch in the period from 9 months to a year.

The onset of estrus is evidence that the animal is ready for mating, pregnancy and childbirth. Please note that Yorkies may have deviations from the specified limits - everything will depend on the conditions of detention and the pet’s diet.

The frequency also depends on the pet’s health: physical and psychological. General indicators: once or twice a year. If the bitch suffered from illness or was exposed to stress, the cycle will be disrupted.

Important: too frequent periods of estrus should alert the owner of a Yorkie. This is a reason to visit the veterinarian; there may be a hormonal imbalance.

Signs of the first heat:

• discharge: burgundy color, with a slight odor;
• swelling of the genitals, redness. The dog behaves restlessly, constantly trying to lick the disturbing area;
• the bitch begins to mark places in the apartment;
• the psychological mood changes: anxiety, fussiness, aggression is possible;
• trying to find a partner. A bitch can run away from her owner on the street. During this period, it is recommended not to let the animal off the leash;
• the bitch takes characteristic poses indicating readiness for mating: raises the pelvis and tail.

It is not a fact that your pet will become restless and fussy. Some individuals, on the contrary, are characterized by lethargy and apathy.

Important: for breeding bitches it is very important to carefully monitor the onset of the first or next heat.

The discharge can be very scanty and unnoticeable. The dog can lick them. If the owner is concerned about this, it is worth seeking help from a veterinarian. If you miss the onset of the first such state, during a walk any male dog can smell the heat and begin to cage.

Symptoms

Before a Yorkshire Terrier bitch goes into heat, she almost always changes her behavior and also experiences some physical changes:

• the dog begins to become noticeably nervous and stops obeying, not following the usual commands;
• some individuals begin to actively play with the owner and constantly follow him;
• the bitch begins to mark her territory, both in the apartment and on the street, thereby trying to attract the attention of male dogs;
• the pet tries to run away from the owner in search of a male;
• There is an increase in the dog’s genitals, and bloody discharge appears.

All these symptoms will help you understand when your pet’s first heat will begin, as well as determine each subsequent onset in the future.

Sometimes the discharge is so small that the Yorkshire terrier bitch manages to lick it off. The owner may simply not notice the onset of estrus. Therefore, if you suspect that it has begun, but there are no main symptoms, to be completely sure, you can do a blood test and take a smear from your pet’s vagina at the clinic. In general, estrus without bloody discharge may indicate a problem in the dog’s body. It is better to consult a veterinarian.

Main stages and duration

The average duration is 21 days. The first heats are characterized by shorter duration and fewer symptoms. The estrus period in Yorkshire Terriers, like all dwarf breeds, goes through the following stages:

1. Proestrus - it is characterized by bloody discharge and swelling of the loop. The dog behaves restlessly or apathetically and refuses to mate. In any case, the pet's behavior changes significantly.
2. Estrus. The stage begins 10 days after the first. It is he who is considered the most successful for mating. The bitch is ready and allows the male to approach in order to mount.
3. Meaestrus - ten days. The bitch is already losing interest in males, the discharge becomes transparent. And the number is decreasing. Behavior returns to normal.
4. Anestrus is the resting stage between estrus. Lasts from 100 to 150 days.

If mating and pregnancy are not planned, you should pay special attention to the dog on the street. Males smell the peculiar smell of the bitch during this period, so they can cage very quickly. In addition, mating can occur with a street dog, which can infect a Yorkshire terrier girl with serious diseases.

Stages of heat

It is very important to mark the first day of the period, especially if this is the first heat in the pet's life. Signs that a new cycle of egg separation has begun are the following features of the pet’s behavior and appearance:

• bloody discharge appeared in the form of dark red odorous specific puddles. They appear daily for six to nine days;
• the animal leaves its marks everywhere, and often does this right in the apartment;
• on a walk, the terrier tries to run away from the owner: instinct demands immediate mating.

It is important to prevent the appearance of outbred puppies, especially if a planned mating with a purebred male is planned. Otherwise, sterilization is required.

• the animal behaves restlessly, does not listen to commands, and may show aggression towards the owner;
• the genitals turn red and swell;
• the dog takes a characteristic pose, raising its pelvis and tail.

? Regardless of how long the heat lasts for Yorkshire Terrier bitches, it can be divided into three main phases.

The first phase is called proestrus. During this period, the dog begins to have bloody discharge, and due to the influx of blood, its loop - the external genitalia - swells. Males are already paying attention to the peculiar smell, but the bitch is still aggressive towards them.

Ten days after the start of discharge, the second phase begins - estrus. It is during this period of estrus that the Yorkshire Terrier bitch is ready for fertilization and allows male dogs to approach her. She shows this with a certain pose - she raises her pelvis and moves her ponytail to the side.

The last phase is called metaestrus and lasts about ten days. Despite the fact that males are still interested in the bitch, she has already lost all interest in them. The discharge gradually becomes transparent, and then stops altogether, and the uterine processes are restored. The dog's behavior returns to normal.

The period of rest until the next estrus is called anestrus and lasts about one hundred to one hundred and fifty days.

The very first heat makes the dog ready for mating. However, there is no need to rush. Mating is carried out no earlier than the age of one and a half years, during the third cycle.

Mating should not be allowed before 18 months: the animal’s body is not yet ready to bear puppies. Little ones endure childbirth very difficult.

This period usually takes two to three weeks, although sometimes it can be much shorter and last 10-12 days.

Training at this moment is pointless; the Yorkshire Terrier is not able to concentrate.

The heat of any Yorkshire Terrier bitch is divided into 3 stages:

1. Proestrus. At this stage, bleeding begins to appear and the loop swells. But the bitch doesn’t allow male dogs yet;
2. Estrus. Begins 10 days after the onset of proestrus. This stage is most suitable for mating;
3. Metaestrus. Lasts approximately 10 days and is the final stage of the process.

The pause between estrus lasts 100-150 days, and is called anestrus.

The first day the egg begins to separate is an important moment in the animal’s life. Physiological signs are visible, the dog’s behavior changes noticeably.

1. The first sign is the appearance of bloody discharge, dark red in color, with a specific odor. Lasts 6 - 10 days.
2. During walks, attempts are made to escape, the animals have a strong instinct, and a signal sounds to mate immediately.
3. The bitch marks her own territory, including marks right in the apartment.
4. The genitals swell and turn red.
5. The time is marked by the manifestation of aggression towards the owner, the dog stops obeying, and anxiety is noticeable.
6. The animal begins to stand in a pose, keeping its pelvis and tail raised.

Frequent urination is a clear sign that this event is approaching. In addition, on the eve of estrus, the following changes in the dog’s behavior are observed:

• appearance of nervousness;
• refusal to follow commands;
• desire for active games with the owner;
• placing marks during walks and at home to attract a male;
• attempts to escape.

If you notice changes in behavior and there is no bloody discharge, contact your veterinarian. Sometimes these manifestations are insignificant, so the dog manages to lick them off, which makes it difficult to understand whether the period has come or not. To determine if you are in heat, a vaginal swab is taken and a blood test is performed. The absence of menstruation with the above symptoms indicates the presence of the disease.

Mating

If the purpose of breeding is to make a profit, you should make sure that the dog’s documents are properly prepared. The club in which the bitch is registered must obtain permission to breed. Otherwise, the puppies will not receive documentary confirmation of their breed.

The norm is for a Yorkie female to start estrus at 8-10 months. It may come earlier, but this does not mean that the bitch is ready to breed. The readiness of the bitch to give birth will determine the health of the newborn puppies. Signs of readiness:

• The weight of the expectant mother should be 2-3 kg. A smaller weight (1.5 kg) is insufficient for pregnancy; the dog may die during childbirth. If you weigh between 1.5 and 2 kg, delivery by cesarean section will be required;
• age threshold. The best moment for mating is the third heat. It usually occurs at the age of 2 years. At this point, the cycle has been established, the hormonal background is smooth, the dog is ready for pregnancy and childbirth;
• Absolute health - all age-appropriate vaccinations have been completed. Routine vaccination should be carried out no more than ten months before the start of the cycle and no less than one.

Important: it is better to plan your first birth before the age of 4 years, when the birth canal is elastic. The age limit is 8 years.

Breeding rules are considered the norm: one Yorkie female gives birth per year, no more than six in a lifetime.

Rules for mating:

• all conditions must be agreed upon in advance: find a partner, discuss payment, how to get out of the situation when one baby is born, what to do if the mating does not work out;
• The owner of a Yorkie bitch needs to be prepared for the fact that the dog may “refuse” mating for various reasons. We need a backup option;
• About a month before the expected estrus, vaccinations are carried out. This will help the puppies get antibodies from their mother's milk;
• carry out anti-parasitic treatment a month in advance;
• get examined by a veterinarian;
• 10 days before estrus, worm the bitch! Toy breed puppies infected with helminths from their mother may die in the first days of life;
• 5 days before mating, wash the dog with a neutral-smelling product, trim the nails and hair near the genitals;
• On the eve of mating, do not feed the bitch or give her a light dinner. It’s good to take a walk two hours before the event.

To be sure of the result of mating, it is worth consulting with the breeder about the peculiarities of the mother bitch’s cycle. According to general rules, readiness for mating occurs on days 7-14 of the cycle. Such readiness can be noticeable in the dog’s behavior. If your periods are bloodless, a progesterone test, which is carried out in the clinic, will help. It is done on the 7-10th billing day of the cycle.

Mating is always carried out on the territory of the dog. This will give him confidence. The room creates a calm environment without loud sounds, drafts and other distractions. Cover slippery floors with carpet to prevent dogs' paws from slipping. This may result in injury.

Important: if this is your first mating, it is better to invite an instructor.

An hour after mating, the dogs can be fed. To increase the likelihood of pregnancy, the procedure is repeated after a day or two. The bitch is carefully supervised for 2-3 days - during this time she can still become pregnant from other random males.

The result can be diagnosed on day 17; on day 25, the veterinarian will be able to determine the number of puppies using ultrasound. A Yorkie bitch's pregnancy lasts about nine weeks.

Signs of readiness of a female Yorkshire

At what age does a Yorkie go through puberty? Up to 18 months, the mini breed is not yet ready to give birth. Its weight should reach 2 kg. When the first heat begins, it is necessary to monitor the dog more closely, especially while walking outside. Sensing the smell, the male can mount. The consequence of such contact will be a serious burden on the body. For a young female, this can have a bad effect on the bitch’s well-being and mental state.

What are the symptoms of heat in a female Yorkshire Terrier? This important stage in a dog’s life can be easily identified by a change in behavior.

Common signs:

• the female begins to actively mark the territory, and an apartment for living is not excluded. Such acts can be committed even by individuals who have previously demonstrated complete loyalty;
• the dog demonstratively avoids control and tries to leave the owner. It is not difficult to understand the reason: the desire to find a male for mating;
• Over the course of a week, the Yorkshire Terrier may leave specific excretory substances of a dark red color. The sputum will have an unusual odor, and the area of ​​the bitch's loop may show signs of swelling;
• when ready for mating, the dog may often lift its tail and raise its hindquarters;
• the dog stops responding to commands, becomes noticeably nervous and becomes agitated.

Important! Keep a close eye on the dog; she needs to create a barrier to prevent non-pedigreed males from trying to impregnate the female.

How to care for a dog?

At this time, the owner should carefully monitor both the dog itself and its health. The concern should not depend on whether mating is planned or not.

Tip: a special notebook will help a lot. All data is recorded in it, starting from the primary one and all subsequent ones.

You can create a universal table with indicators. The clarity of the records will help you see the slightest deviations from the norm. In addition, it is very convenient when visiting a veterinary clinic. Sometimes, in conditions of excitement, owners cannot remember the necessary information.

Care instructions:

• bleeding can stain furniture, clothing and other household items. In order to protect your apartment from such marks, you can use special panties. They are reusable or disposable (like baby diapers). In addition, you can sew such an accessory yourself. The dog's ability to wear clothes will be very helpful here;
• decorative breeds can go to the toilet on a diaper in an apartment. During the period of heat, the dog can be left at home. If the decision is made to continue walking, walking is carried out strictly on a leash. Remember - in this state, your pet will not hear your commands, even if she is obedient. She is driven by the instinct of reproduction;
• It’s worth thinking about the possibility of breeding in advance. If breeding is not planned, an operation is performed to sterilize the Yorkshire terrier bitch. If an unplanned pregnancy occurs, a veterinary specialist will also help, who can simultaneously stop reproductive function;
• In summer, avoid swimming in natural bodies of water. The water in them is saturated with bacteria, at this time the possibility of infection increases. At the same time, it is necessary to wash the dog in the bathroom - after each walk, using special antibacterial agents, the least aggressive compounds are selected.

Separately, you should pay attention to the discharge that may appear after estrus. If their color is transparent, there is no smell and the quantity is small, the animal is fine. Discharges that should alert you:

• sharp unpleasant (putrid) odor;
• bright colored discharge streaked with blood or pus.

In addition, the bitch may develop a fever, become lethargic, and refuse to eat.

You cannot treat your Yorkie at home; you need to consult a specialist.

Even the dosage of the drug should be prescribed strictly according to the age and weight of the animal. It is very difficult to do this on your own.

Necessary care

Every owner of a Yorkshire Terrier bitch must exercise proper control over his pet, regardless of whether he plans to breed.

For this purpose, you can keep a special notebook, where you need to record the beginning of the first heat and all subsequent ones, and record how many days have passed between them. These records will help you notice any problems in the dog’s body in time and begin timely treatment.

At the slightest suspicion, you should contact a veterinarian; you cannot treat a Yorkshire terrier bitch yourself.

When a female dog is in heat, she may leave bloody spots everywhere. To save carpets and upholstered furniture from discharge, you can purchase special panties at any specialty store or sew them yourself.

These days, you will have to protect the Yorkshire Terrier bitch from the increased attention of male dogs, especially during a walk. You can only take your dog outside on a leash; the reproductive instinct distracts him from your orders, dissipating his attention. You can also leave her indoors while she is in heat.

Lack of control can lead to unplanned pregnancy, which is undesirable for those who decide to engage in breeding. If the owner has no desire to bother with the offspring, he can perform surgery on his pet to stop the reproductive function: sterilization or castration.

During the period of heat, you should not bathe your Yorkshire terrier bitch in bodies of water, since during these days the risk of infection of the genitals increases.

What to do if there is no heat?

The frequency of estrus may be disrupted not only by increasing frequency, but also by its absence at the expected time. The reasons may be:

• borderline age: too young (up to 6 months), old (more than 7 years);
• recent stressful situation;
• being in a state of nervous shock;
• physical exhaustion;
• obesity;
• strong physical activity;
• hormonal therapy;
• undergone surgery.

As a rule, all such conditions are under the supervision of a doctor, the animal takes medications and the owner is warned about the possible absence of estrus. If this comes as a surprise, you should contact the clinic, as the cause may be serious illnesses:

• hypothyroidism is a hereditary disease in many breeds. The disease is characterized by insufficient production of thyroid hormones by the thyroid gland. The cause of cycle disruption can be any pathology of the thyroid gland. If adjustments or treatment are not started, the dog may become infertile;
• Ovarian hypoplasia is incomplete sexual development of an animal. Causes of the disease: hereditary or acquired. Hereditary developmental pathologies cannot be corrected, but acquired ones can be corrected - changes in estrogen levels;
• avitaminosis. Lack of vitamins and microelements is the reason for cycle disruption. In this state, nature does not allow the dog to become pregnant or bear puppies;
• tumors. Any neoplasm of the ovaries will affect the regularity of the cycle. This does not depend on the benignity or malignancy of the tumor. Any neoplasm grows, drawing blood flow onto itself - the intensity of the ovaries decreases;
• severe vaginitis. Swelling of the external genitalia is very noticeable even outside the cycle, and pus is found in the urine.

This is not the entire list of diseases that can disrupt the regularity of a dog’s cycle. If the cause is not known for certain, it is necessary to undergo the necessary examinations, take tests and begin treatment as quickly as possible.

Main features

We must not forget that when a Yorkie goes into heat, the symptoms may not be pronounced and the beginning of the cycle can be easily missed. The lack of interest of male dogs in a female is not a sign by which the process can be determined: deviations are often associated with hormonal levels and the severity of odor.

Stages of the period

How long does a Yorkie dog go into heat: veterinarians divide the period into 4 phases, with their own nuances and behavioral characteristics:

• Precursor or proestrus - lasts 7-10 days, has characteristic manifestations. The pet's genitals increase in volume and swell slightly due to the rush of blood. After a few days, the first spotting appears. The dog is trying to actively mark the territory, show interest in the opposite sex, any attempt to mate causes aggression.
• Rut or estrus is the main period of sexual heat; ovulation continues for 48-72 hours. The phase begins 11 days after the first bleeding. The female shows all the signs of readiness: when stroked, she moves her tail and freezes in a standard pose.
• Metaestrus - lasts from 60 to 100 days, accompanied by a cessation of discharge and a gradual decrease in the volume of the vulva. In response to interest from male dogs, the animal shows aggression, and sexual activity gradually fades. Tests show an increased level of progesterone; in the absence of mating, a false pregnancy may occur.
• The intermediate period or anestrus lasts 4-8 months. The frequency depends on the individual characteristics of the organism and the age of the animal.

Important! How long does estrus last for Yorkies: even for the same individual, the duration of the cycle may differ. The problem of instability of deadlines is associated with the psychological and physical state and associated factors.

Cycle phases in dogs

How often do you go into heat?

When Yorkies finish their first heat, the body adjusts to regular mating. In the standard, the process occurs twice; in some individuals it can occur up to 3 times in 12 months. If the frequency of menstruation is increased, then the pet requires consultation with a veterinarian and a full diagnostic examination.

What to do?

Often the absence of estrus is confused with a condition when it occurs without red discharge, or it is so scanty and pale that the dog manages to lick it before the owner has time to notice. This is especially true for mini Yorkshire terriers. This condition is normal. The time frame for mating is calculated together with a specialist.

If stress is suspected as the cause of the absence of a cycle, the dog is kept quiet and observed. Other actions depend on the root cause:

• if the dog was found on the street or was purchased as an adult, it may have undergone sterilization surgery;
• the presence of a cyst - hormonal therapy or surgery;
• oncology - radio and chemotherapy in the early stages of detection, surgery;
• endometritis, purulent inflammation - antibiotics, antimicrobials;
• pyometra - removal of the uterus and ovaries.

Important: any treatment, from hormonal to antibiotics, requires strict veterinary supervision.

Unreasonable self-diagnosis and selection of medications on the Internet are the path to worsening your pet’s condition. Deaths are also possible.

Yorkie behavior during heat

It is important for every owner not to miss the onset of estrus, since a bitch on the street can attract male dogs, which will lead to an unwanted pregnancy. You can find out everything about the pregnancy of a Yorkshire terrier here. In addition, early mating will have an extremely negative impact on the health of the animal, when you can mat a pet is described here.

The imminent onset of estrus is indicated by changes in the dog's behavior:

• The bitch becomes nervous, begins to obey poorly, and ignores the usual commands;
• Activity increases, the animal begins to follow the owner everywhere;
• The dog may begin to mark the apartment and the street. Thus, the animal attracts members of the opposite sex;
• The pet tries in every possible way to escape from the owner and go in search of the “lover”;

It is worth noting that changes in the behavior of a Yorkie during estrus depend on the characteristics of the body and the character of the animal. So, one pet may become excessively aggressive, while another bitch may turn into a lethargic, sleepy animal.

In addition to changes in behavior, the onset of estrus is indicated by swelling of the Yorkie's genitals.

In some individuals, the discharge is insignificant, and the dog manages to lick it off. In this case, the owner runs the risk of not knowing whether the dog is in heat. If you suspect that this natural process has begun, but there is no discharge, you can confirm your suspicions by donating blood and a smear for examination at a veterinary clinic.

Estrus may be accompanied by a complete absence of bleeding, in which case it is necessary to consult a specialist.

Methods to prevent estrus

Yorkies are a decorative breed, the cost of puppies can be high. Currently, many owners purchase representatives of the breed to make them simple home companions, without the purpose of breeding. In this case, you can apply some measures that will avoid periodic estrus.

Sterilization

If the animal was purchased without the purpose of breeding, it is worth performing an operation to stop the reproductive function. In this case, hormones will be produced, mating will remain possible, but fertilization of the egg will not occur.

Tips for conducting:

• You can sterilize your Yorkie before the first heat, or two months after the next one;
• before the operation, it is necessary to undergo a full examination with tests, ultrasound examinations of organs, etc.;
• If possible, you should contact a clinic that has equipment for laparoscopic intervention.

The whole process takes about 30 minutes, recovery is fast. The main problem: caring for the Yorkie during recovery from anesthesia, caring for sutures if the intervention was carried out with incisions.

Castration

There is an opinion that the difference between castration and sterilization lies in the gender of the patients: females are spayed, and males are castrated. This is wrong. During the process, the bitch's uterus and ovaries will be removed. The operation can be performed for medical reasons or at the request of the owner.

Sexual heat of even such a small dog as a Yorkie is a test for the owner. The dog needs constant supervision, clothes and furniture are dirty everywhere, the pet itself is nervous or sits lethargically.

Rules:

• the procedure is carried out before the onset of the first heat (5-6 months);
• A complete examination of the dog is necessary - castration has a number of contraindications. If available, replace with sterilization.

Castration cancels further production of hormones and their effects on the body, and can:

• reduce the risk of cancer: breast cancer, transmissible sarcoma;
• prevent pyometra, endometritis;
• stabilize the dog’s nervous system;
• extend the life cycle of the animal.

Of course, any manipulations of this kind must be carried out in the sterile conditions of a veterinary clinic by experienced specialists. During the period of recovery from anesthesia, it is better to leave the bitch in the hospital so that, if necessary, she can be provided with adequate assistance. The incisions from surgery are so small that they are practically invisible on the dog’s body. Self-absorbing sutures are applied unless there are contraindications.

Contraceptive drugs

Modern veterinary pharmacology has a wide range of multidirectional agents: preventing ovulation, normalizing hormonal explosion, reducing odor during estrus, etc. They can be used urgently or if there are contraindications to surgical interventions.

Types of drugs:

• injection. Injections appeared relatively recently and still cause a lot of controversy. This method is effective (interrupts estrus), but has a lot of contraindications. Its effect on the body causes great harm;
• tablets - contain a dose of artificially synthesized hormones that inhibit the activity of the ovaries or create a background of false pregnancy. Feature - application is effective only in the period before the onset of estrus. During the period of ovulation there will be no benefit, only harm;
• drops on the tongue - interruption or delay of ovulation. Apply only before the start of the cycle;
• drops on the withers - interrupt ovulation at the initial stage. In addition, they stabilize the psyche, removing aggression and anxiety.

It would seem that these are convenient products that can always be bought at a veterinary pharmacy; there is no need to take the animal for surgery. But each of the listed types has a large list of serious contraindications. In addition, owners often prescribe drugs on their own, without taking into account physiology, age and day of the cycle.

Contraindications:

• hormonal contraception cannot be used during the first estrus, lactation, or pregnancy;
• in the presence of compactions in the mammary glands;
• in the presence of any type of tumors or neoplasms on the body;
• cannot be used when the bitch begins puberty;
• diabetes;
• pathologies of the genitourinary system.

Many experts advise using drugs only in exceptional cases, after consultation and examination of the dog.

Possible side effects:

• diseases of the genitourinary system, kidneys, heart muscle;
• inflammation of the uterus and mammary glands;
• hormonal imbalance;
• infertility;
• increased aggression while taking hormones.

Please note that Yorkies have low body weight and it is difficult for them to calculate the dose of any type of drug. An allergic reaction to any component may occur. Hormonal effects can cause more harm to health than the benefits of regulating sexual activity.
