Reeling in shock!

I found a flea on my dog!  A flea!  The laundry machine is going like crazy to wash her blankets, I’ve got Borax (which has boric acid in it) sprinkled on her favorite bits of chair and carpet, and she has suffered the indignity of a heavy duty bath.  We’re both reeling from the experience.  I feel sullied; she just feels wet and overwhelmed.
