SanDnMila, have you done anything to treat your home? Flea eggs love to hide in carpets and bedding, even sofa cushions if your dog goes on there. Your dog can be flea free and continually reinfect themselves if the eggs are still hidden in your house and hatch into more fleas. Have you tried a product called capstar? It will kill all the fleas on your pet within 24 hours, its an oral tablet they take once. you can get it from your vet its helpful to use that first and then apply the preventatives.
