Apple Cider Vinegar! A spoonful of this stuff added to your dog’s water makes their skin more acidic and not-at-all tasty to fleas. If apple cider vinegar is not your dog’s cup of tea, you can dilute it 50/50 with water, pour into a spray bottle and use as a repellent.
Does anyone know of an all-natural flea spray I can use on my dog? I don't want to use the chemical ones recommended by vets.
