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.

Why do some men have skin over there penis?

Do you mean why do men retract their foreskins and expose the end (the glans) of their penis? This generally occurs all by itself when the penis is erect, as the normally loose foreskin is stretched tight when the penis stiffens and extends in length. Many guys also retract the foreskin by hand when they urinate because it reduces the likelyhood of their urine splashing around, it also avoids trapping urine droplets under the foreskin. All guys should retract their foreskin when bathing or showering to ensure that they wash their penis properly and thus avoid unpleasant smells and infections.

Does a stallion horse have a medical problem if his penis constantly hangs down out of the sheath?

Yes, this is medical issue called priaprism if the stallion is unable to retract his penis. However, some stallions seem to prefer "letting it hang loose" and voluntarily allow their penis to relax out of the sheath for extended periods of time. If you notice chapping of the skin over the glans (the end of the penis), swelling or that the stallion is having difficulty urinating, this would be a reason to have the vet out to take a look. If your stallion cannot pass urine at all, this is a medical emergency.

Acetylpromazine maleate causes?

Acetylpromazine maleate (commonly called "ace") causes muscle relaxation and mild to moderate sedation. However, in male horses occasionally there is an idiopathic side effect of permanent periphimosis, in which the horse is no longer able to retract his penis inside the prepuce. For this reason, Ace is generally not recommended for use in breeding stallions.
