I hope you can get it under control soon. I had a flea problem many years ago so now I use advantage on everyone every month and I've never had a problem since. I have to use it year round because we have a mild climate here and also because I live in a condo complex and my front door opens up to a main hallway that's carpeted. If one person here has an animal with fleas then they spread quickly so it's better to safe than sorry.

I've been buying my flea meds online for several years now and I buy the largest dog advantage and then I measure it out according to how much everyone weighs. My vet has approved this and it really saves me a lot of money too. Good luck.
