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!

    Hi and thanks for using Petco Pet Education Center, formerly Petcoach! I would consult your vet or even contact Bayer the manufacturer of this product. I am not comfortable advising it but I am comfortable advising Frontline be used. Frontline has a long and safe history of use during pregnancy in dogs, especially in Europe. Good luck.
