Abortion in Boston Terriers

Posted by

You keep a close eye on your Boston Terrier while she is in heat, but she manages to escape.  You may now have a pregnant dog and this isn’t what you wanted.  Have you considered an abortion in Boston Terriers?

Accidents happen, and a large number of pets become pregnant despite their owner’s wishes. In most cases, the best solution to this problem is to have the bitch or queen spayed, which will not only solve the current problem, but prevent it from happening in the future. Ovariohysterectomy during pregnancy, unless very close to term, does not pose significantly elevated risks to the animal over and above the standard surgery.

Before discussing treatments for pregnancy termination, one point should be made: Just because an bitch in estrus is found together with a male doesn’t mean they have already mated. In fact, it seems to be the case that a majority of bitches presented to veterinarians for “mismating” treatment are not pregnant.

Estrogen Treatment for Mismating

A variety of estrogens have previously been recommended and used as treatments for mismating. Two of the most popular formulations have been diethylstilbestrol and estradiol cypionate (ECP).

Other Methods for Terminating Canine Pregnancy

Several other drugs have been investigated experimentally for terminating canine pregnancy, and while some show considerable promise, these treatments either are not currently available or cannot yet be recommended due to lack of data from clinical trials. Examples include:

Dopamine agonists: Drugs such as bromocryptine and cabergoline, which bind to dopamine receptors in the pituitary gland, suppress prolactin secretion and can terminate pregnancy in dogs by suppressing progesterone secretion from the corpus luteum.

Dopamine agonists are effective in terminating canine pregnancy only after about 25 days of gestation. Like PGF, they require repeated treatment and commonly induce vomition and inappetence.

Epostane: This drug inhibits steroid hormone synthesis by inhibiting the enzyme that converts pregnenolone to progesterone. It has been shown to terminate pregnancy in dogs after a 7 day treatment and appears to have this effect throughout gestation.

Mifepristone (RU486): This well-known drug acts as a progesterone antagonist. Small clinical trials have demonstrated that his drug is very effective in terminating canine pregnancy after 25-30 days of gestation, and without apparent adverse effects.

Clearly, several drugs appear to have promise as safe and effective abortifacients in dogs, and deserve additional research and marketing attention as aids for pet population control.
