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.
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.
How long do dogs have their periods?
When a dog is in heat, which is a natural component of the estrous cycle, they may go through a sort of “period.” Dog “periods” normally last between two and four weeks, though the exact length can vary depending on your dog. Your dog might try to attract male dogs and mate during this period. Consider seeing your veterinarian about whether you should get your dog spayed if you’re unsure of what to do when your dog is in heat.
Female dogs experience periods, albeit the timing is slightly different from that in humans. Dog periods typically last between two and four weeks, though they might differ from dog to dog. The estrous cycle is another name for a dog’s “period,” and you may hear people refer to this as a dog “being in heat.” The material in this page applies to all of these terms because they are all interchangeable.
What should you do if your dog has begun their estrous cycle and how long do dog periods last? We’ll go into more detail about your dog’s estrous cycle in this post, including how long it lasts, how frequently it happens, how to spot a dog in heat, and what to do if your dog is in heat.
How long does a female dog have her first heat cycle?
A female dog will go through estrus, or heat, generally every six months from the time she is about six months old until the end of her life. She is most amenable to mating during this time. Your dog will show clear signs of hormonal changes suggesting she is in heat, such as a swollen vulva, bleeding, more frequent urine, and an increase in agitation or attentiveness. She’ll also raise her rump and hold her tail off to the side to greet male canines.
When does heat start?
Smaller breed dogs can go into heat as early as four months, but the typical age is closer to six months. Some large breeds may wait until they are 18 to 24 months old before they experience their first heat. Breeding young female canines during their first and second cycles is strongly discouraged. Both the dog and their eggs have not yet reached full development. Your veterinarian will be able to let you know when your dog is grown enough to breed if you intend to do so.
How long is each cycle?
Typically, heat lasts for two to four weeks. A female dog may not be receptive to male dogs early in the cycle, while others remain receptive the entire cycle. You’ll know the cycle is ended when all of her vulva returns to its normal size and there is no more bleeding or discharge—it could be shorter or longer. Your dog’s fertile window during the heat cycle is rather brief; it may start approximately nine or ten days after she goes into heat and last for about five days. She can conceive up until the end of the cycle, though.
Is this a lifetime thing?
It could take some time for the cycle to normalize after estrus starts. It can take some dogs up to 18 months for their cycles to become regular. During these early stages, keeping a record is a smart idea. The average interval after that is roughly every six months. Smaller breeds may go into heat up to three or four times per year. Only once every 12 to 18 months, larger canines like Irish Wolfhounds, St. Bernards, and Great Danes may go into heat. Female dogs endure estrus throughout their lives, unlike humans, albeit the intervals between cycles will lengthen.
The majority of pet owners choose to neuter their female dogs before the first heat, with the exception of purebred breeders. According to some specialists, this lowers the chance of disorders including breast cancer and other illnesses. Additionally, it eliminates the chance of unintended litters.
