Is there such a thing as a morning after pill for dogs and is it safe?

Marion, there is a pill called Diethylstilbestrol (DES) that is used for other medical issues but is capable of causing an abortion in a dog. It is not the most reliable of methods and as far as I know, most vets will not prescribe it for that purpose. If you think that your dog may be pregnant, please call your vet for direction.
