When a female dog is about six months old, she becomes sexually mature. Estrus, also known as heat, refers to the part of the cycle when she is open to mating. Her ovaries produce eggs after a significant drop in estrogen levels followed by a surge throughout this stage. Although a dog’s first heat usually occurs when it is six months old, this can vary greatly. While larger breed dogs may be as old as two years before their first heat, other canines can go into heat as early as four months. Breeders who are doing their jobs never breed a dog during her first or even second heat. It is recommended to hold off until her third heat, which occurs at around 18 to 24 months. Your veterinarian will carry out the required genetic testing and be able to let you know when your dog is prepared.
How can you tell if your dog is in heat?
Estrus manifests itself in both physical and behavioral ways. She might go more often than normal. Additionally, the vulva will swell and the discharge will have a bloody tint. She can appear anxious or preoccupied. She will be open to having sex with male dogs and may even start things off by “flagging,” which is when a female dog lifts her rear in their direction. A female dog will actively court males in the middle of the cycle and may do so until the cycle is over.
How often will my dog go into heat?
Every six months on average, female dogs go into heat. However, this can change, particularly at first, so it’s a good idea to keep track. Some canines may need 18 to 24 months to establish regular cycles. Small dogs may go into heat three or four times a year or more frequently. Great Danes and St. Bernards, among other very large breeds, may only go into heat once every twelve months.
The estrus cycle typically lasts three weeks on average, however this can change by two to four weeks. It starts with vaginal discharge and vulvar puffiness and concludes when all bleeding has stopped. A female may consent to being mounted at any time during the menstrual cycle, while the majority actively seek out mounting later in the cycle.
Although the intervals between estrus will lengthen as your dog ages, she will continue to go into heat throughout her life. With practice, dog owners improve their ability to spot the beginning of and properly care for their pets during this normal life cycle.
Breeder Education Courses
This is your time to learn as well; training isn’t only for animals. Visit the AKC Breeder Education Platform, which was created to meet your needs for ongoing education. Introduction to breeding, genetics, anatomy, whelping, and nutrition are among the course’s themes.
Vaginal Bleeding
Your dog is likely in proestrus and about to enter the heat phase if you see bloodstains in the vicinity of where she rests. During this stage, dogs may bleed for up to 10 days.
What is the duration of a puppy’s first heat?
When a dog reaches adolescence, its first estrous (reproductive or heat) cycle will occur. Each cycle has multiple stages; the estrus stage is when a female is capable of becoming pregnant. A dog in the estrus stage is frequently described as being in heat or in season.
Puberty (or sexual maturity) usually occurs at around six months of age, but breed differences may apply. Smaller breeds typically experience their first estrous cycle at a younger age, but huge and giant breeds may not experience their first heat cycle until they are between the ages of 18 months and 2 years old.
How often does a female dog come into heat?
Although the frequency might vary between breeds and from dog to dog, the majority of dogs go into heat twice a year, or approximately every six months. Giant breed dogs may only cycle once every 12 months, however small breed dogs may cycle three times annually. It’s typical for young dogs’ cycles to be a little erratic when they first start reproducing. A female dog may take up to two years to establish regular cycles. With the exception of Basenjis and Tibetan Mastiffs, which normally cycle in the spring, (domesticated) dogs do not have a specific time of year when they procreate.
What are the signs of estrus?
The vulva will expand or engorge with the first symptom of estrus, though this swelling may not always be visible. A bloody vaginal discharge is frequently the first indication that a dog is going into heat for a pet owner. Sometimes the discharge won’t be noticeable until a few days after estrus has started. From dog to dog, the amount of discharge varies.
The first indicator of a dog going into heat for a pet owner is sometimes a bloody vaginal discharge.
As the cycle goes on, the color and appearance of the vaginal discharge will alter. The discharge starts off fairly crimson, but as the days go by, it thins down and turns pinkish-red and watery in hue. When a female dog is in heat, she may urinate more frequently than usual or exhibit marking behavior, when she urinates in small amounts on various items both inside the house and outside while on walks. Her urine at this time of the cycle contains pheromones and hormones that let other dogs know she is in a reproductive state. For this reason, male dogs in particular will be drawn to female dogs that are in heat.
Male dogs may start marking your property with their pee in an effort to reclaim their territory if they notice a female in heat from a distance.
How long does estrus last?
When a dog is in estrus, she has the potential to give birth. A dog will typically be in heat for 1 1/2 to 2 weeks, though this can vary depending on the individual and can be shorter or longer.
At what stage of the estrus cycle is the dog able to get pregnant?
The female dog typically ovulates around the time that the vaginal discharge turns watery; this is the point in her life when she is the most fertile and open to mating. She could become pregnant at any time while she is in estrus because sperm can remain viable in the reproductive system for up to a week and still be able to fertilize the eggs. Contrary to popular perception, tying with the male dog is not a need for a female to become pregnant (for further information see the handout “Estrus and Mating in Dogs”).
How can I prevent my dog from becoming pregnant?
Having your dog surgically sterilized (either by an ovariohysterectomy or a spay procedure) before her first estrous cycle is the best approach to keep her from getting pregnant. Most veterinarians advise conducting an ovariohysterectomy before the dog is six to seven months old because it can be challenging to estimate when this first cycle will take place.
Is there anything I can do if my dog has been mismated, or accidentally mates with another dog?
If this occurs, you must speak with your veterinarian right away. Within the first one to two days following mating, mismating injections can be employed, however there are hazards involved. Your veterinarian will go over your options and any potential dangers.
Should I let my dog have an estrus cycle or a litter of puppies before spaying her?
There are no justifiable justifications for allowing a dog to have a litter of puppies prior to spaying her. However, the general consensus at this time is that spaying will increase a dog’s lifespan. More recent research has shown that some larger dog breeds, such as Labrador Retrievers, Golden Retrievers, and German Shepherds, may benefit medically from delaying their spay surgery until after their first heat cycle. Dogs can become pregnant during their very first estrous cycle, which raises the possibility of an unintentional breeding. Dogs can breed with anyone; this includes siblings, parents, and even children; a son can breed with his mother.
It’s a frequent misconception that allowing female dogs to have a litter of puppies will make them friendlier and more outgoing. This is untrue and does nothing but exacerbate the critical issue of dog overpopulation.
How long does a dog’s first heat last?
There are four phases in the canine estrus cycle:
1. Proestrus: The first seven to ten days of menstruation. The vulva starts to swell at this point, and your dog starts bleeding. Though she will begin attracting male canines, she is not yet prepared for mating.
2.Estrus: The estrus cycle’s mating phase occurs during this time. It persists for 5 to 10 days. The bleeding can lessen or stop. During this time, your dog is prepared for mating.
3.Diestrus: This time frame can range in length from 10 to 140 days. Either your dog is pregnant at this time, or she is taking a rest.
4.Anestrus: This is the lull before the subsequent heat cycle, which lasts for about six months.
When do dogs go into heat each year?
Birds are chirping, flowers are budding, and new life is emerging. And spring is also the time of year when many animals enter “season, or have a heat cycle, if you have a female dog that has not been neutered.
When a female dog is in her heat cycle, also known as estrus, her body is prepared for reproduction. Dogs normally have a heat twice a year and start going into heat between the ages of 6 and 12 months (earlier for small breeds, later for larger breeds).
Dogs may show one or more indicators of estrus, or none at all. Your dog may exhibit any of the following:
Pet dogs that won’t be bred should ideally be spayed or neutered before their first heat cycle. Here are a few causes for this:
How should I get ready for my dog’s initial heat?
The most crucial thing to keep in mind is that if a female dog is around an unfixed male dog while she is in heat, she could become pregnant. She may be cranky and wants to breed. What can you do to assist your dog in heat then? Follow these advice:
- Make sure she is housed or maintained in a safe enclosure away from other dogs. Contact with male dogs who haven’t been neutered can result in an unintended pregnancy, and even contact with dogs who have been spayed or neutered might cause hostility due to hormones.
- Keep messes to a minimum by using doggie diapers, and give her what she wants, whether it’s space or love.
- Make certain she has her own bedding, food bowl, and water bowl in her space.
- Now is the moment to breed her if you plan to. The optimum breeding procedures should be discussed with your veterinarian.
- Wait one month after your dog’s heat cycle ends before having her spayed.
Your dog’s heat cycle can be easily managed with the right care and resources. If you observe that your dog’s heat cycle is unreliable, if there is persistent bleeding or discharge, if you suspect that your dog may be pregnant, or if your dog’s behavior changes, make an appointment with your veterinarian.
What occurs when a puppy experiences its first period?
Your dog will go through four phases of her heat cycle, each of which will be marked by distinct physical and behavioral changes. The canine heat cycle has four stages, which are as follows:
- Proestrus: The beginning of the heat cycle, when your dog’s body is getting ready to mate A swollen vulva, blood-tinged discharge, excessive vaginal licking, clinging behavior, and hostility toward male canines are symptoms of this stage. Additionally, your dog might tuck her tail close to her body.
- Estrus: Your female dog will be receptive to men during the estrus phase, which is the mating phase. Your dog may seem to be urinating more frequently than usual because she is leaving birthmarks on her body to show that she is ready to procreate. Even though she might be leaving urine stains in some places, her vaginal discharge will likely slow down and possibly turn straw-colored. Your dog will approach males with her tail held to the side when she is ready to mate, but she can act aggressively toward other females.
- Diestrus: This stage follows the “in heat stage and gives your dog’s body the chance to either revert to normal or go into pregnancy. Her vulva will enlarge once again, and the flow from her vagina will stop.
- Anestrus: Anestrus is a dormant phase during which no noticeable changes in hormone levels or sexual behavior occur.
Must I allow my puppy to have her first heat cycle?
Working at our Carmel animal hospital allows me to constantly interact with new folks who have recently acquired puppies, which is one of the best aspects about my job. These are always highly exciting visits that provide a wealth of information on a range of canine health concerns and behavioral problems. We frequently talk about spaying or neutering the dog.
Why should my dog be neutered? You haven’t been to the Humane Society for Hamilton County if you need to ask this. I put in a lot of effort for the Humane Society, trying to fund surgery for animals who are still without homes. The most obvious cause is the issue with pet overpopulation, but there are numerous others that also affect your own dog. At my Carmel animal hospital, I frequently see intact female dogs that suffer uterine infections. This is a serious issue that can be resolved by spaying. According to a recent study from the University of Illinois College of Veterinary Medicine, spayed female dogs live an average of 28% longer than unspayed female dogs. It’s also convenient to not have to deal with bleeding and a diaper for two weeks twice a year. Unless a dog is going to be utilized for breeding, work, or show, I advise spaying every dog.
When should my dog be neutered? I advise spaying your dog when she is 6 months old. Although this procedure can be done earlier and is frequently done on dogs acquired from shelters to prevent the return of six more puppies, 6 months is the optimal age for your pet.
Do I need to let my dog have one heat cycle? For most dogs, the answer is NO. The greater the number of heat cycles your dog experiences, the greater the likelihood that she may eventually get breast cancer. Before the first heat, the dog can be sterilized at our Carmel animal hospital, effectively eliminating any risk of breast cancer. We advise you to do let your dog go through one heat cycle for one common cause. Over their vulva, some dogs develop a skin fold that can collect urine and moisture, eventually leading to skin diseases. If there is a probable issue, it will be evaluated in our animal hospital in Carmel.
