Fleas can carry disease and other parasites, including tapeworm. And fleas are extremely irritating for your dog. They often cause intense itching, which in turn can cause your dog to damage his/her skin by vigorous scratching.
Knowing about the options for flea treatment for pets is essential. Natural flea treatment is the option I personally go for, but I understand that many people either prefer the chemical advantage flea and tick or frontline flea treatment, or are simply not aware that natural flea treatments are in fact available.
