Young and inexperienced males may become so excited that they ejaculate<br />

before intromission. This is more likely to happen if attempts are made to<br />

guide the male by taking hold of his penis behind the bulb.<br />

A mating between a tall dog and a short bitch can present mechanical<br />

problems. The solution is to stand the male in a ditch or breed on a slope to<br />

equalize the difference.<br />

Small dogs can be mated on a table with a piece of carpet or nonslip rug on<br />

it for good footing. Support the female with a hand beneath her pelvis.<br />

A PROLONGED TIE<br />

A prolonged tie is one that lasts for an hour or longer. The problem is caused<br />

by a spasm of the constricting vulvar ring. The ring maintains the dog’s erection<br />

by preventing the blood from leaving the bulbus glandis and returning to<br />

the body. Eventually the animals become frustrated and begin to tug against<br />

each other, aggravating the problem.<br />

Do not throw water on the dogs or try to pull them apart. Instead, turn the<br />

male so that he mounts the female and then push on his rump to increase the<br />

depth of penetration. This relieves the constricting effect of the vulvar ring<br />

on the penis and allows the bulb to subside.<br />

SHY BREEDERS AND DOGS WHO WON’T MATE<br />

SEX AND REPRODUCTION • 443<br />

The most common reason why dogs refuse to mate is that it is the wrong time<br />

in the estrous cycle. If mating is attempted too early in the cycle, the bitch<br />

may growl and snap at the dog, or she may allow the male to mount, only to<br />

sit down or jump away as he starts to thrust. This is normal proestrus behavior,<br />

but some breeders may misinterpret it as a sign that mating won’t take place.<br />

A simple test to check for estrus is to stroke the female’s vulva when she is<br />

relaxed. A bitch in estrus raises her vulva and flags her tail to the side. These<br />

signs indicate that she is hormonally ready for breeding. If it is the right time<br />

and she continues to refuse the male, then quite likely the problem is psychological.<br />

Psychological factors are much more common than hormonal or physical<br />

ones.<br />

A female raised as a house pet may be a shy breeder because of inadequate<br />

social contact with members of her own species. Mate preference, too, can be<br />

a determining factor. A bitch who runs with a certain dog may mate willingly<br />

with that dog but refuse another. Some females are willing to mate only with<br />

very aggressive males.<br />

In males, sexual aggressiveness may be influenced by unpleasant associations<br />

with sex. Some owners scold or punish a dog for showing sexual behavior<br />

toward dogs or people. Thus the dog comes to believe he will be punished if he
