I don't think you are going to get a clear answer on this. I've included the company's drug information below.

Their recommendation is to consult with your veterinarian if your dog is pregnant. I have looked for any information about this product in pregnant dogs and cannot find any which likely means that there hasn't been any testing done. So, the answer is that we likely just don't know if this is safe for pregnant dogs. There are flea and tick products that are listed as safe for pregnant dogs, so I would consult with your veterinarian for a recommendation.
Good luck! Thanks for using PetCoach.

Hi, thanks for using Petco Pet Education Center, formerly Petcoach! Frontline Plus is labeled for use in pregnant dogs. K9 Advantix is NOT labeled for use in pregnant dogs and using it is considered off label use. I hope this helps and good luck!

Is Frontline flea and tick treatment really safe for my pregnant dog?

Yes, Frontline is considered to be safe for use in pregnant female dogs. The active ingredient (fipronil) has never been shown to cause any birth defects or other problems, and it's poorly absorbed into the body in any case so should not affect the developing pups at all :)

Is flea shampoo, chewables, or vaccines safe for my pregnant dog?

Hi, thanks for using Petco Pet Education Center, formerly Petcoach! It depends on the active ingredient in the shampoo, but likely no. Pyrethrins are not safe in pregnant dogs. I would contact your Vet for Fipronil products or look online. I am assuming by "children" you mean the puppies and not human children. If you want to tell me the name of the shampoo and the chewable tablet I can look in to it's safety. I do not recommend vaccinating pregnant dogs. I hope this helps!

Can I use Seresto on my pregnant cat? What flea treatments are safe?

Hello. The manufacturer recommends consulting your veterinarian before using the collar. Generally, this means that testing was never done on pregnant or lactating cats. It is probably safe, but if anything happens, the manufacturer will not take any responsibility. I recommend one of the Frontline products, even the newest one, Frontline Gold. It states on its label that it is safe for use on pregnant & nursing cats. Thanks for using Petco Pet Education Center, formerly Petcoach.

What flea medication is safe for a nursing dog and her puppies?

Yes, Capstar (nitenpyram) is labeled as being safe for use in pregnant and lactating dogs. Just remember that Capstar will quickly kill adult fleas, but will not provide lasting flea prevention against hatching flea eggs or maturing flea larvae. K9 Advantix II is also labeled as being safe for pregnant and lactating dogs and will provide month-long flea prevention, but you would need to closely monitor the puppies to keep them away from the areas of medicine application. I hope this helps and that all goes well!

Is Nexgard enough flea protection, and what's safe for pregnant dogs?

You do not have do use anything else if you use Nexguard, if you start finding fleas just switch to a different type of flea treatment such as Bravecto or Advantage. When pregnant the only safe product is Frontline.

Are topical flea and tapeworm treatments safe for pregnant dogs?

Frontline and Revolution are safe for use in pregnant dogs. If you're already using a heartworm preventative with ivermectin, please continue to do so as it is safe for both the mom and pups and will help prevent her from passing parasites to the pups. And if they is due for vaccinations, getting them while she is pregnant will boost her and the pups immunity to disease. For tapeworms, Drontal is safe to use during all life stages, including pregnancy.
