How It Works:
Sentinel Flavor Tabs are used to treat parasites that are found externally and internally in a dog’s body.  They are made up of 2 chemicals, lufenuron and milbemycin oxime, that work together to control parasite infestation including…

  • fleas
  • heartworms
  • roundworms
  • hookworms
  • whipworms


Lufenuron belongs to a class of drugs known as insect development inhibitors / insect growth regulators.  This chemical inhibits flea development within the egg, which prevents fleas from ever maturing to an adult.  The other chemical used in Sentinel is milbemycin oxime.  This chemical acts by disrupting nerve transmission within the flea leading to death.
