Dog reproduction It is a complex process that, generally, begins with courtship, in which male and female emit signals to imply that they are prepared for the ride and consequent copulation.Once the mount is produced, we observe that the male disassembles the female but the penis is inside the vagina, showing both dogs together.It is at this point that we ask ourselves why this is done and if we should separate them or, on the contrary, they do it naturally.p>
In this Animals and Pets Online article we will answer these and more questions, clearing the cause that explains why dogs stay stuck when they mate , keep reading!
How is the male dog's reproductive system
In order to understand more easily why dogs get caught when they mate, it is essential to briefly review the anatomy of the reproductive system of both the male and the female.So, the The dog's internal and external apparatus is made up of the following parts:
- Scrotum .Bag responsible for protecting and keeping the testicles of an adequate temperature dog.In other words, it is the visible part of these glands.
- Testicules .Located inside the scrotum, they have the function of producing and maturing sperm and male hormones such as testosterone.They have an ovular shape, are located horizontally and tend to be symmetrical.
- Epididyms .Located in both testicles, they are tubes responsible for storing and transporting sperm to the vas deferens.These tubes are composed of head, body and tail.
- Deferential duct .It starts at the tail of the epididymis and has the function of transporting sperm to the prostate.
- Prostate .Gland that surrounds the bladder neck and the onset of the urethra, and whose size is not similar in all races, varying significantly from one to another.Its function is to generate a substance called prostatic fluid or seminal plasma to facilitate the transport of sperm and nourish them.
- Uretra .This duct is not only intended to transfer urine from the dog's bladder, it is also part of the canine reproductive system by transporting sperm and prostatic fluid for its final ejaculation.
- Foreskin .Corresponds to the skin that covers the penis to protect and lubricate it.This second function of the foreskin is thanks to its ability to produce a liquid called esmegna, greenish in color, for this purpose.
How is the female reproductive system
As with the male's apartment, the dog's reproductive system is made up of internal and external organs , some of them guilty of the fact of keeping the dogs hooked after the monta.Next, we briefly explain the function of each of them:
- Ovaries .Oval shaped, they have the same function as the testicles in males , produce ovules and female hormones such as estrogens.As with the prostate of the male, the size of the ovaries may vary depending on the breed.
- Oviducts .Tubes located in each one of the ovaries and whose function is to transfer the ovules to the uterine horn.
- Uterine horn.Also known as "delutero horns", they constitute two tubes that transport the ovules to the delutero body if they have been fertilized by sperm.
- Utero .This is where the nesting of the zygotes is carried out for p roast to become embryos, fetuses and subsequently puppies.
- Vagina .It should not be confused with the vulva, since the vagina is the internal organ and the vulva the external.In the dog, it is between the cervix and the vaginal vestibule, being the place where the copula is carried out.
- Vaginal vestibule .Located between the vagina and the vulva, it allows penetration during riding.
- Clitoris .As with women, the function of this organ is to produce pleasure or sexual stimulation to the dog.
- Vulva As we said, it is the external sexual organ of the dog, and changes in size during the period of heat.
But...why do they get hooked after riding?
Once penetration occurs, the male tends to "dismantle" the dog, staying attached to it and leading the owners of both animals to wonder why the dogs have been stuck during mating and how to separate them.This is because the ejaculation of the dog occurs in three phases or fractions:
Urethral fraction .It is carried out during the beginning of the penetration, and in it the dog expels a first liquid completely free of sperm. Sperm fraction .After the first ejaculation, the animal completes the erection and goes on to emit a second ejaculation, this time with sperm.During this process, there is a increase in penis bulb size due to venous compression of the penis and consequent blood concentration.At this point, the male turns and dismounts the female, leaving the dogs stuck. Prostatic fraction .Although the male already has dismantled the female, the coupling has not ended, since once turned the so-called "buttoning" occurs by the expulsion of the third ejaculation, with a much smaller number of sperm than in the previous one.Once the bulb is relaxes and regains its normal state, dogs disengage.In total, the copula can last between 20 and 60 minutes , 30 being the usual average.
Of this shape, and once the three phases of male ejaculation have been reviewed, we see how the cause that answers the question why dogs get stuck when they mate is the expansion of the penile bulb.It is such a size that it reaches, not It can pass through the vaginal vestibule, which closes precisely to guarantee this fact and avoid damaging the female.
Should I separate two hooked dogs?
Clearly not .The male and female antomia does not allow the penis to be removed before the end of the third ejaculation of the dog.If separated by force, both animals would be injured and damaged, and the copula would not come to an end.During this phase, the animals should be left to carry out their natural riding process, allowing them a relaxed and comfortable environment.
It is usual to listen to the female emitting sounds similar to crying and even grunting or barking, however, and although she can lead her human companions to consider that she needs to be separated from the male, the most advisable thing is not to promote stress and, as we say , let them separate themselves.
Once the copula is produced, if the eggs have been fertilized and the dog enters a state of gestation, it will be necessary to provide a series of care, so we recommend consulting the following articles:
