Got Fleas? Dish Soap Kills Them! by Helen Fazio, Travel Dog Blogger, www.traveldogbooks.com Fleas are wingless insects with mouthparts adapted for piercing skin and sucking blood. Equipped with spiny hairs to anchor in a dog's coat, they are armored and resistant to crushing or scratching. They serve no purpose in the great chain of being, except to cause discomfort and spread disease. One safe way to remove a sudden infestation is to shampoo your dog well with Lemon Joy or Dawn dish soap. These grease-cutting shampoos will kill existing fleas by swiftly destroying the cuticle on their exoskeletons, but you will have to act proactively to prevent further attacks in the immediate area. Special thanks to Buttercup and Miss Dixie Monroe for this great tip!
