There are many prescription and non-prescription treatments to kill fleas on dogs. Prescription treatments, such as oral tablets and topical medications, kill fleas and ticks for up to one month. Certain treatments target the problem by preventing flea eggs from hatching.
Non-prescription treatments, such as collars, powders and sprays, can be obtained from pet supply stores or supermarkets. There are also natural products made from plants that repel fleas, ticks and mosquitoes. Geranium, lavender and cedar oils are typically used in holistic flea treatments. Owners can also use powders and sprays to kill fleas that may be living on carpets and furniture.
