Yup - definately fleas... best bet is an all-out war approach....
When Honey got fleas, we treated her with Frontline Combo, and with Johnsons 4Flea tablets (can be used alongside Frontline, and kills adult fleas when they bite, so helps reduce the irritation for the dog - they wouldn't solve an infestation, but help the dog in the meatime). Washed and sprayed (With Indorex) all bedding, and all the throws and cushions on the sofa etc. Vacuumed and the sprayed the carpets, sofa, curtains etc (fleas can jump up to 3 feet), again with Indorex.... and then repeated the washing, vacuuming and spraying 7 days later. Nothing kills one of the stages of the flea's life-cycle (I think it's the Pupa stage) so you WILL get a resurgence of fleas in a few weeks time, but they will still be killed off by the steps you have taken now.
We also flea-combed (and drowned the fleas in soapy water) Honey daily, and gave her a bath with flea shampoo...
