Rochelle had posted that her ferrets had aquired a few fleas from a dog
that was on Program.  Program works as a kind of sterilizer for the fleas.
Once a flea bites the dog the eggs it lays will not hatch.  If these fleas
that the ferrets picked up had "lunched" on the dog they probably wont
multiply, if not you may need to treat again.
