You may also observe that her vulva is large, red, or swollen with some bleeding or blood-tinted discharge. Your dog will only bleed for around half of the total cycle, usually 7 to 10 days. Generally, bigger dogs bleed more than smaller dogs, but it varies between dogs.
Dog “periods” typically last about 2-4 weeks, but that duration can vary a bit depending on your dog. During this time, your dog may try to attract male dogs and mate. If you're not sure what to do when your dog is in heat, consider talking to your vet about whether you should have your dog spayed.
Stage 1: Signs a Dog Is in Heat
The first signs your dog is in heat are the swelling of her vulva and bright red bloody discharge. This stage is called proestrus. "There will be lots of licking," Nielsen says. A dog in heat can bleed for around seven to 10 days.
The cycle often happens twice per year. The American Kennel Club (AKC) writes that some smaller breeds can go into heat up to four times per year, and extra-large dogs, such as St. Bernards or Great Danes, may only experience it every eighteen months.
A heat cycle lasts two to three weeks and begins as spot bleeding from the vulva. Your dog's vulva will also become swollen, and she may urinate more often than normal. Her excessive urination is meant to attract male dogs. Estrus cycles are not a medical condition but a natural reproductive cycle in dogs.
Your dog will only bleed for around half of the total cycle, usually 7 to 10 days. Generally, bigger dogs bleed more than smaller dogs, but it varies between dogs. Some dogs bleed very little.
Heat usually lasts between 2-4 weeks. Early in the cycle, a female dog may not be receptive to male dogs, although some are receptive through the entire cycle. It can be shorter or longer and you'll know the cycle is over when all her vulva returns to its normal size and there's no more bleeding or discharge.
Estrus is the stage when the dog can become pregnant. Although this can vary with each individual, on average a dog will be in heat for 1 ½ to 2 weeks but this can be shorter or longer.
Dogs do not menstruate and are only receptive to mating when actively in heat. Do dogs go through menopause? No; dogs can become pregnant throughout their entire lives. There's no short answer to explain the reproductive cycle of a female dog, especially in comparison to the human menstrual cycle.
Since the female dog heat cycle bears symptoms comparable to a woman's menstrual cycle in many ways, it is possible to conclude that during your dog's heat cycle she is uncomfortable and maybe even experiences cramping and mild amounts of pain.
Yes, veterinarians can spay dogs in heat.
While frequency varies according to breed and individual dogs, usually dogs go into heat about twice a year or every six months. Each estrus period lasts about 18 days.
There are some old wives' tales that a dog should go through at least 1 heat cycle before she's spayed. This just isn't the case. Studies have shown that the risks of mammary cancer and urinary incontinence are higher if you wait to spay your dog after she's gone through 1 or more heat cycles.
Heat can be messy, having a packet of baby wipes on hand ready to go can help keep your home clean. Some dogs can get quite snuggly during their heat cycle, so make sure to make time for extra cuddles. Also make sure you dog has plenty of access to fresh clean water.
A dog's body experiences lots of changes when she's in heat. Because of these changes, your dog may experience some changes in behavior and even some pain. Much like humans, female dogs experience cramps and hormonal changes when their bodies are preparing to mate.
A: A dog is said to be in heat when they are in the proestrus and estrus stages of their reproductive cycle. During proestrus and estrus a dog will have bloody discharge from the vulva, and during estrus, a dog can get pregnant.
When should I spay my female dog? We recommend waiting until your dog is at least over 6 months and likely even older for larger dogs. The benefits are much more pronounced in larger dogs, but there is not a lot of difference for lap dogs.
Diestrus: Your dog's body is recovering from the estrus phase and is no longer fertile. You'll see less flirtatious behavior, reduction of any swelling, and discontinuation of vaginal discharge.
Answer: A normal heat cycle in dogs typically lasts an average of 7 to 14 days. If a female dog's bleeding goes on longer than that, then it is worthy of wondering whether something's going on. At times, some dogs may develop ovarian cysts, and these may cause irregularities in a dog's heat cycle.
Appetite changes are common when female dogs are in heat. While the majority of dogs will experience a decrease in appetite, some may experience an increase (Farricelli, 2016). Whether your dog has a small appetite or if she is hungrier than usual, feeding her nutritious food is key.
If you see blood coming from your dog's vulva, it could be a result of trauma, tumors, infections, anatomic abnormalities, blood clotting disorders, and conditions affecting the urinary tract. Your dog should be evaluated by a veterinarian unless she is known to be in heat and there are no other issues.
