re: Flea treatment for dogs?

Flea shampoo to kill fleas currently on the dog. If there is pet bedding remove it from the house or wash it.

Vacuum asap. Multiple times a day until fleas confirmed gone. This keeps the population under control and makes it much easier to knock them out. They reproduce amazingly fast and then the struggle becomes much longer and harder.

Buy PT Ultracide. It's sold on Amazon. Use it wherever you think they may be. Follow the instructions as you will need to vacate the house for awhile after using it and wear protective clothing/face wear.

I would do all this in conjunction with getting your dogs on oral anti-flea medication.

I have dealt with a few flea outbreaks in our house over the past several years with our dog and it was miserable but I have learned a bit from them. Fast action to keep them manageable is key and know that you need to monitor even after you think they are gone because they can come back strong if any survive. Be prepared to treat multiple times over a few weeks.
