Sulfa-based drugs are the most common medications prescribed for coccidiosis in dogs. Sulfa-based drugs are considered by most to be harmful to pregnant dogs, meaning alternate treatment must be prescribed.

Identification
-
Coccidiosis is a disease resulting from infestation with the parasite coccidia. Coccdia protazoa wreak havoc on a dog's intestines and stomach.
Significance
-
Most dogs do not display symptoms of coccidia. Dogs that are young, elderly, pregnant or have compromised immune systems may display diarrhea, dehydration, weight loss, anorexia, seizures and death.
Treatment
-
Most coccidiostats, or drugs that control coccidiosis, are sulfa-based antibiotics. Coccidiosis responds very well to these drugs, but most veterinarians will not administer them to pregnant dogs, as they cause birth defects. Off-label use of the horse-worming drug ponazuril has proven safe in effective in pregnant dogs who caught coccidiosis in shelter situations.
Considerations
-
Unless symptoms are severe, most veterinarians will advise you to wait to treat coccidiosis until your dog has given birth to treat her and her puppies. In some cases, supportive care in the form of fluids and anti-emetic drugs may be necessary for the duration of the pregnancy.
Expert Insight
-
Speak to your veterinarian about alternative options when treating coccidiosis in a pregnant dog. Your veterinarian is in the best position to evaluate your dog's condition and the risks that accompany it.
