A female dog reaches sexual maturity at around six months old. The stage of the cycle when shes receptive to mating is called estrus, or heat. During this stage, theres an increase in estrogen levels, then a sharp decrease and then her ovaries release eggs. Although six months old is the average age of a dogs first heat, this can vary widely. Some dogs can go into heat as young as four months, while larger breeds may be as old as two years before their first heat. Responsible breeders never breed a dog on her first or even her second heat. It is considered best practice to wait until her third heat, at about 18-24 months. Your vet will perform any necessary genetic testing and will also be able to tell you when your dog is ready.
How long do dogs stay in heat and how often?
Similar to the start time, the exact frequency of estrus depends on your dog’s size, breed, and age. Female dogs who have not been spayed go into heat twice a year, around every 6 months. Each heat cycle lasts around 18 days, for generally anywhere from 2 to 3 weeks.
How soon can a dog come back into heat?
Dogs will typically come into heat again within 3 to 4 weeks and experience a normal cycle. This is a common issue in younger dogs during their first heat, in which case the issue usually resolves on its own.
How long is a dog in heat bleed?
A dog in heat can bleed for around 7 to 10 days. During this first stage of the reproductive cycle, the female will not accept a male.
What are the signs that your dog is going into heat?
3 Some females will have irregular cycles, especially if they are very young or very old. Small breeds may cycle three times per year, while giant breeds may only cycle once every 12 months. Unlike some other species, canine estrous cycles are not dependent on the seasons, sunlight, or temperature.
If youve ever had an unspayed female dog in your home before, chances are you bought mountains of doggy diapers. Unlike cats, dogs experience more discharge during their heat cycle, or estrus phase, but that is only one of the signs indicating your pooch is ready to mate. Having an unspayed dogespecially if you also have an intact male dogin your home can be a challenge, but knowing what to expect can help prevent problems from arising.
With clues gleaned from your female dogs physical appearance and behavior, you can determine which stage of her heat cycle she is experiencing. Signs seen during this phase include a swollen vulva, blood-tinged discharge, excessive licking of the genital area, clingy behavior, and aggression toward male dogs.
Diestrus: This phase occurs directly after the in heat stage and allows your dogs body to either return to normal or develop into pregnancy. Although your dog may have excellent obedience skills, her recall ability may fall by the wayside when shes influenced by her hormones and is intent on finding a male. If the unthinkable happens and your dog escapes from your yard or runs off, ensure you can be reunited with legible, updated ID tags and current microchip contact info.
Occasionally, a female dog can experience health issues after a heat cycle when the uterine lining remains thickened and produces more fluid, creating the ideal environment for bacterial growth. A pet with a pyometra may drink excessively, have a fever, vaginal discharge, decreased appetite, or appear lethargic.
When a female dog is in heat or going into heat, it means shes open and receptive to mating and is releasing mating hormones. Some signs of a female dog going into heat may include lower energy levels, more aggressive behavior, differences in leg-raising while urinating, urinating more often than usual, and even running away from home. This is unlike male dogs, who do not experience heat cycles.
A female dog in this stage of the heat cycle is resistant to male company and may exhibit changes in personality, appetite, and more frequent tail tucking. The proestrus and estrus stages of the dogs heat cycle can last anywhere from two to four weeks collectively.
A female dog can first experience her heat cycle as early as six months of age, but this varies with breed. As a pet parent, its a good idea to verse yourself well on the signs of a dog entering their heat cycle. Increase indoor supervision: You should stay mindful of your dogs whereabouts and keep her off furniture , as she may naturally leave some blood spotting behind and potentially stain surfaces.
Pads can also be used to allow her to enjoy her preferred resting spot without the risk of leaving stains behind on furniture or carpet, and providing for easier cleanup at regular intervals. There are multiple types of diapers for dogs in heat to choose from, including disposable and reusable garments.
Puberty or sexual maturity in the female dog usually occurs around six months of age. The smaller breeds tend to go into oestrus or “heat” earlier and some females can have their first “heat” cycle as early as four months of age. On the other hand, the large and giant breeds can be up to two years old before they come into heat for the first time.
Vulvar swelling should be taken as the first sign in addition to the female paying increased attention (such as licking the area) to her rear end. From the beginning of the heat period she will be attractive to male dogs, but will usually not be receptive, or allow mating, until about 7-10 days later.
Dogs can be desexed whilst they are in season, but generally we try to do the surgery 8 weeks after the start of their last oestrous cycle. Most vaginal smears are performed serially, over several days, to look for changes in the cells that predict ovulation and the best time for breeding. Surprisingly, male dogs appear to be more stress sensitive than females during mating.
The time of mating is extremely critical and it is highly recommended that you have tested your female to determine the optimal days for breeding. Also, inquire as to the procedure if your female dog does not become pregnant as a result of the stud service. It is common for owners of the male dog to offer a free service next time.
How Often Are Dogs in Heat?
The dog heat cycle, also known as the estrus cycle, is a biological event where a female dog is most receptive to mating. It usually lasts anywhere between two and four weeks, and a female dog will experience this about every six months. A dog in heat may exhibit strange personality and physiological changes throughout the cycle.There are four stages:Study each stage to help you identify when your female furry friend may be going into heat.
How Long Are Dogs in Heat?
The proestrus and estrus stages of the dog’s heat cycle can last anywhere from two to four weeks collectively. However, it may still vary as the cycle officially begins and ends with the swelling and return to normalcy of the vulva. The pregnancy status of a female dog will affect how long she remains in the diestrus stage; the anestrus stage of the dog’s heat cycle is simply the resting stage that intermits the next one.
When Do Dogs First Go Into Heat?
A female dog can first experience her heat cycle as early as six months of age, but this varies with breed. A smaller dog may first experience their heat cycle earlier than a larger dog, who may not experience theirs until up to two years of age. Female dogs will continue to experience heat cycles throughout their lives up until death, but the time between each cycle will increase with age. Female dogs don’t experience menopause.
Reproductive Season, Heat, Oestrus, And Pregnancy Tests
Puberty or sexual maturity in the female dog usually occurs around six months of age. The smaller breeds tend to go into oestrus or “heat” earlier and some females can have their first “heat” cycle as early as four months of age. On the other hand, the large and giant breeds can be up to two years old before they come into heat for the first time.On average this occurs about twice a year or every six months, although it varies from dog to dog. When cycling first begins, there may be a great deal of variability in the time between cycles. This is normal. Some females take eighteen months to two years to develop a regular cycle.There is no evidence that irregular heat cycles predispose the dog to false pregnancies or pyometra (uterine infection). Small breeds tend to cycle more regularly than the larger breeds. Three and occasionally four heat cycles per year can be normal in some females.Very large breeds may only have a “heat” cycle once every 12-18 months. In most giant breeds (Great Danes, Irish Wolfhounds, St Bernard’s, etc.) an oestrus cycle every twelve months is common.”Heat” cycles vary, but average two to three weeks for most dogs. “Heat” should be considered to begin with the first signs of vulvar discharge, or when the female begins licking or paying attention to her vulva. The vulva will begin to appear swollen. It ends when all discharge ceases and the vulva has returned to its normal size.The most notable sign is vaginal bleeding. This may not become apparent until a few days after the female has actually come into oestrus. Vulvar swelling should be taken as the first sign in addition to the female paying increased attention (such as licking the area) to her rear end.From the beginning of the heat period she will be attractive to male dogs, but will usually not be receptive, or allow mating, until about 7-10 days later. The discharge will usually become less bloodstained at this time.Some females experience heavy vaginal bleeding during oestrus. If you are concerned, please consult your veterinarian.You may also find that she is passing small quantities of urine more frequently. The urine contains both pheromones and hormones which signal any interested males that she will be receptive soon.When an animal is in season, there is an increased blood supply to both the uterus and the ovaries. Dogs can be desexed whilst they are in season, but generally we try to do the surgery 8 weeks after the start of their last oestrous cycle.This can be difficult. Most ovulate and are receptive around the eleventh day of oestrus. The discharge will then be less bloody and the female will be actively looking for a male. However, ovulation may occur either early or late during the “heat” cycle.
