THE VET HAS THE STRONGEST STUFF YOU WILL BE ABLE TO GET AND A YOUNG DOGS HAS TO HAVE CERTAIN THINGS, ANYTHING ELSE CAN KILL IT. THE VET WILL GIVE YOU THE BEST TREATMENT AND THE BEST SHAMPOO FOR THE FLEAS.
If you want the fleas dead as quickly as possible, use Advantage or Advantix. It literally works within just an hour or two of application. If you want somethign that may take a little longer ot kill them, but could possibly last longer than 1 month (2 to 3 months in some cases), check out Frontline Plus.
Msboxers is right, Advantage and Advantix can be used on puppies that are as young as 7 weeks old and weighing more than 1 lb. Frontline Plus can only be used on puppies that are 8 weeks or older and weighing at least 11 lbs.
Vacuum constantly,we sprinkle sevin dust (the kind ok for*animals* use, found in your garden section of stores) in the carpet to help kill eggs and fleas. If theres no snow where you are sprinkle it in the yard too.
I use it in the summer on the big dogs for mosquitos and flys too..

I like to use Sergeants flea and tick once a month application. It smells like oranges and for my dogs it works very well. My oldest dog is 8 1/2 and she has never had fleas since I have been using this. You can get it at Wal Mart for about 7.00.
