re: Flea treatment for dogs?

You can give your dogs a Capstar which will kill any adult fleas on them within a few hours, then put them on a monthly flea treatment. We use Advantage II but there are many brands out there.

For the house treatment I bought a can of this to have on hand in case of your scenario. Haven't had to use it yet.

My 02 cents. Good luck.

You can also bathe them in dish soap to kill adult fleas but in my experience they still find places to hide to avoid the soap.
