Good afternoon. My pregnant dog has tapeworms. I noticed thus rice looking worms and was just adviced at Petco it is tapeworms. They didn't have any medication to treat it but just one. They were not sure if it's ok for a pregnant dog.

Praziquantel ( http://www.drsfostersmith.com/product/prod_display.cfm?pcatid=35693 ) is the best medication available to treat tapeworms, which resemble grains of rice. It is considered safe for pregnant and nursing dogs, and is a category B drug during pregnancy according to the FDA (basically that animal studies have not demonstrated a risk to the fetus). It should be perfectly fine to give Lilu this medication. Since tapeworms are transmitted by eating either tapeworm infected fleas or rodents, be sure that Lilu is receiving a high quality flea preventative regularly. Frontline (while not always my favorite flea preventative) is safe for use in pregnant dogs. I hope that all goes well!
