You don't get doggy abortion usually. You go to get your dog spayed and discover that she is pregnant and they just include it in the regular spay fee. Any surgery for a dog during advanced state of pregnancy is higher risk. If you catch the unwanted mating within 72 hours you can just do something equivalent to a morning after pill for dogs. But for the treatment it is a associated with a high risk of inducing uterine disease. PGF hormones may be safer and has a few side effects in dogs, including vomiting, panting, cramps excessive salivation and defecation. Many vets will refuse to do this treatment as it does have risks. As to what treatments like this cost, here is what most vets go by. They will make it more expensive than a spay to keep people from using it instead of not breeding: "The drug costs associated with this protocol are negligible; however, the preparation of vaginal smears and daily hospitalization may be cost prohibitive for some owners. We also recommend follow-up ultrasonography at midgestation to confirm the nonpregnant status. If pregnancy is detected, termination may be attempted or the bitch be allowed to proceed to term. We advise that the total cost of treatment not be less than that of ovariohysterectomy, so that this, or any other, method of pregnancy prevention (termination) will not become an alternative to permanent sterilization. The protocol outlined in this article is currently the safest and most effective method for preventing pregnancy in early diestrus in our hands. CVJ"

no, not a bit. 38 cents is all

Someone seems to be offended by this question. Why?

Are you planning on getting her spayed? If so, often vets will abort a new pregnancy to do so. If the pregnancy is in later stages, it could kill the dog.

There is another question already on here that is very similar. Perhaps it'll be of some help: http://www.answerbag.co.uk/q_view/541753
