How do you get rid of dog flea?

There are topical coat sprays and prescription applications (some contain fipronil and require only once-monthly application). Flea and tick shampoos range from limited-use, active shampoos, to milder medicated ones, to simple citrus-containing dishwashing liquids (which will drown adult fleas and repel new ones). A flea or tick collar is another alternative to topical applications, and all treatments should include reducing the fleas in the house, yard or other living areas.
