Fleas are the bane not only of dogs, but of dog owners. You can tell your dog is infested not only because he or she is scratching frantically, but because of the flea feces in the dog’s fur. Fleas will not only hop from your dog to you and your family, but will also drop eggs on your carpets to continue the life cycle. Feeding your dog some brewer’s yeast and garlic every day can help the dog more ‘unappetizing’ to fleas. A solution of lemon-water can be spritzed onto your dog, too. Fleas don’t like the smell of citrus and this will help to repel these parasites. Sprinkle diatomaceous earth on your carpets (vacuum up the excess) to kill flea larvae and hatching adult fleas – the diatomaceous earth scratches through the insects’ exoskeleton, killing them.
