The absolute best flea treatment I've found, hands down, is Advantage.
It's available either from a vet, or (somewhat cheaper) from large pet
food stores. Once you have the fleas under control, a once-monthly
application Advantage is all you'll need.

In the UK we have a flea treatment called "Frontline" - is this the same
thing as "Advantage". It comes in little phials and one phial is
applied on to the skin between the dogs shoulder blades. The dose is
according to size/weight. One treatment protects the dog for three
months against fleas and one month against ticks.

Hope this helps.
