Hot spots are prevented by preventing fleas. The most common methods of flea prevention include topical flea medication and oral flea medication. Some of the most effective topical medications include Frontline Plus and and K9 Advantix II. These products begin killing fleas within minutes. Topical Revolution also kills fleas, but requires at least 24 hours to become effective.
The most effective oral flea prevention medications are Sentinel and Capstar. Capstar kills all adult fleas and begins acting within minutes. Capstar is given daily. The main difference between these two oral flea medications is that Sentinel doesn't kill adult fleas. Sentinel prevents eggs from developing into adult fleas.
