The fleas joyously jump in and suffer horribly.
Much fun.
Spot treat the dogs with Vet’s Best non-toxic flea spray available at PetCo or PetSmart.
Give them weekly baths with Dawn original style [blue] dish detergent.
Buy some ‘Skin So Soft’ from Avon.
Seriously.
Keep the Skin So Soft away from a Formica countertop. It will ruin it. I don't know what it will do to Corian, but I have a countertop in my bathroom that was destroyed by the above product.
