I will be doing the Frontline. Let's hope a single application will do it. I will have to do all my dogs.

Costco sells their Kirkland brand of Flea topical. I've been using it for a couple season , works just as good as Frontline. for your pregnant girl, I would use Frontline.

For the first time. The Frontline did not work. Frontline plus did.

Advantix works great too but not sure with pregnancy or nursing.

Frontline and Plus is safe for both

When I see a flea I use a flea a comb on a regular basis, a nice bonding moment. vacuum the house, wash bedding, and I even vacuum the dogs :) Most like it, some don't, if they don't - I don't bother. Feels like a massage. I use the open end of the hose, be sensible, try it on arm or leg first, and then dispose of the bag when done. repeat as necessary, if your dog like it.
