No, a dog’s penis cannot go through a human cervix and into the womb. The anatomy and size differences between species prevent this from occurring. Additionally, interspecies mating typically does not result in successful reproduction due to genetic incompatibility.
If you mean, "why do dogs get tied together when they are mating", well, the canid penis has a little extra feature called the bulbus glandis. When the dog's penis is erect, the bulbus glandis looks very much like a ball-shaped structure near the base of the penis and about twice the width of the penis shaft. (It is -not- the dog's testicles; those stay right where they're supposed to be.) When a dog mounts a bitch, he inserts his non-erect penis (supported only by the penis bone, the baculum) into her vagina and thrusts while his penis becomes fully erect. During this, the bulbus glandis swells, locking the dog's penis into the bitch, and soon afterwards the dog begins to ejaculate semen. The two shift so that they are standing rump-to-rump and stay locked for 2-40 minutes, during which the dog continues to ejaculate. Eventually, the dog's penis detumesces and the bulbus glandis shrinks, allowing the dog and bitch to separate.
Yes, that is the natural color of a dog's erect penis.
The male's penis swells so that he can stay inside the female to ensure his sperm will enter, in order to conceive. Her vagina's walls clamp on his penis and she relaxes the muscles and lets him go when she is ready.
The exposed part of a female dog is not the womb and NO you should not.
Does your dog have a penis? If yes, then he's a male. If there's no penis, it's broken. Return it for a new dog.
A male dog will have a penis.
my penis!
The penis of a dog enlarges due to increased blood flow during sexual arousal or mating. This engorgement helps the dog achieve successful mating by facilitating penetration of the female's reproductive tract.
The male dog would have a penis
It lasts as long as your Penis through a letter box whilst being licked by an Iranian dog
WHAT????
First of all, WHY ON EARTH WOULD YOUR PENIS BE IN A DOG?! and secondly, I recommend some form of lubricant.
