SENTRY® Natural Defense™ Natural Flea & Tick Squeeze-On for Dogs & Puppies kills and repels fleas, ticks and mosquitoes for up to four weeks, yet it’s safe for use around children and pets when used as directed – even in multiple-pet households.

Each carton contains three monthly applications that feature natural active ingredients such as peppermint oil, cinnamon oil, lemon grass oil and thyme oil.
