Abortives

Why has my veterinarian prescribed this medicine?

Various types of medication are used for pregnancy termination (abortion) in female dogs. One type of medication (estradiol) needs to be given soon after mating to be effective, the other type of medication (aglepristone). may be given up to 45 days after mating. However, side effects such as loss of appetite, fœtal expulsion, and swelling of the mammary glands may be seen at the time of abortion in dogs treated more than 20 days after mating.

A partial abortion may occur in 5% of dogs. Your veterinarian may need to monitor your pet after treatment to check that the medication has worked and that pregnancy has been terminated.

Continual hormonal control of pregnancy may cause side effects in your pet. If your dog is not intended for breeding, think about having your pet spayed (sterilised, neutered).
