How often do dogs menstruate?

2022-07-08



Some pooper scoopers will find that their little female dog will bleed when she comes into heat, and will put on her dog's physiological pants to prevent getting it everywhere. Many people say that this is the same as for dogs and humans, to the physiological period, to get a period.



I. Dogs are the opposite of humans


And in dogs, it's not called the menstrual cycle, but estrus. The average female dog is in heat twice a year and in contrast to humans, where menstruation is the discharge of an unfertilized egg and some shed uterine epithelial cells, which means there is no pregnancy at this time.

The bleeding phenomenon in dogs, however, is not menstruation, but the mucus that permeates the epithelial cells of the uterus, to indicate that mating can take place at this time and that the dog is ready to become pregnant. And the bleeding in mammals will be repeated throughout life except in the case of pregnancy and disease; while in humans, menstruation will end at menopause.

II. How a dog's "period" looks like


A normal female dog will have her first period at about 1 year of age. Dogs are not seasonal breeding animals, and females generally come into heat about 6 months apart, twice a year. It varies slightly from breed to breed and from dog to dog in different living environments.

Most bitches come into heat for the first time in the spring from March to May, and for the second time in the fall from September to November. The most obvious manifestation of the "period" is the swelling and bleeding of the vulva, and the dog will also appear depressed, moody, urinate frequently, and move forward on their initiative when they see the opposite sex.

The amount of bleeding varies from dog to dog, and some dogs have little or no bleeding. Usually lasts about ten days to half a month. Some dogs will lick themselves clean and the owner will not even notice.

Three, special periods require careful care


1. Female dogs in estrus are prone to poor mental state, poor appetite, and become easily constipated. Owners can feed them more vegetables and high-fiber dog food, give them warm water in time, and avoid eating cold, irritating food.

You can also give the dog some calcium and trace elements to enhance the dog's immunity. If fed meat must be washed with water, cooked, and then fed, to prevent parasites inside raw meat.

2, at this time the dog's body is relatively weak, and resistance has also decreased, this time do not bathe the dog, if the dog is dirty, use a towel to help them wipe the body, and timely blow dry, to avoid causing disease.

3, you can put on the dog's physiological pants, but according to the dog's body type choose the right size of physiological pants, otherwise, it will cause the dog uncomfortable. The physiological pants should also pay attention to change, has been wearing will not be breathable and cause bacteria breeding.
When you are at home, you can leave the physiological pants on, the hygiene situation at home is better, and the dog does not have any big action at home and will take care of itself. If you go out to walk your dog, it is best to wear physiological pants to prevent bacterial infection and the proximity of male dogs.

4, regular disinfection of kennel and dog contact items, such as blankets, mats, etc., sunny days more out to the sun, sterilization, to ensure that the dog's living environment is clean and tidy.

5, the dog will clean up their blood, sometimes not clean, the owner can use wet paper towels to help them wipe a wipe, to avoid infection and disease.

6, the dog's first heat, when the dog has not yet fully developed, the body is not suitable for pregnancy, take the dog out must be tied to the leash! The female dog is in heat and the male dog will instinctively contact, which must prevent the occurrence of accidental pregnancy. Owners who want their dogs to have children can wait until their dogs are in heat for a second time before breeding them.

Fourth, many other animals besides dogs also have "periods"


Animal experts and executive director of the Chinese Veterinary Association, Shi Jiangbin, said that animals will begin to regularly produce an estrus period after puberty. Most mammals, such as kangaroos and tailless bears, will have one to two estrus periods a year, while a few, such as the large rat, will have one every 4 to 5 days.

In these animals, there are small spiral arteries in the endometrium that start to spasm and contract, causing the distal vessel walls to rupture and bleed, but not in the lower mammals such as rabbits and mice, so they do not bleed.

One of the differences from other mammals is that cats also do not have periods, they have their unique physiology, and if the owner finds that the cat is bleeding, the cat likely has a disease.

V. Why don't meows have their period?


Meows in estrus do not show obvious blood flow, and occasionally bright vaginal discharge appears, but generally meows with a cleanliness fetish will dispose of it on their own. This is because they stimulate ovulation during estrus due to mating, and if the eggs are not fertilized, they are destroyed in the uterus by white blood cells and are not expelled from the body.

Cats do not expel their eggs also to maximize egg utilization, and kittens start ovulating only after they have found a suitable boyfriend. So the chances of a female cat getting pregnant after mating are as high as 90%, and I must say that meowing cats are still very resourceful to reproduce their offspring.

But if once you find your female cat has lower body bleeding, the owner must be alert to the following possible causes

1銆乻erious gynecological disease: for example, repeated heat without fertility, the resulting pus accumulation in the uterus can lead to vaginal bleeding in cats.

2銆両ntestinal parasites: Severe parasitic diseases can also cause lower body bleeding, which the owner may mistake for vaginal bleeding without careful observation.

3銆丠emorrhoids: this has a lot to do with the cat's diet and living habits. The owner can check the cat's anus for redness and congestion; observe whether the cat's stool is normal and whether there is blood in it.

These phenomena must be found in time to take the cat to the hospital to avoid delaying the condition.
After all these tips on pet holidays, I think the most important point is that for those pets whose bodies have not yet developed in the heat for the first time, or the owner does not intend to let the pet pregnant at this time, a little to protect the pets, do not easily contact with the opposite sex, otherwise, it is easy to an accidental pregnancy, which can cause harm to both the baby and the mother.

To avoid overpopulation and a series of reactions during estrus, owners can choose to take their pets to be spayed or neutered, the most suitable time for spaying or neutering is between 6 and 9 months old, and the time will be slightly different for different pets. Studies have shown that neutered pets live a year or two longer than unneutered pets.

The development of spay/neuter surgery is now very mature, and the risk of surgery is very low, so owners can choose their pets according to their situation.
