Sentinel must be administered monthly, preferably on the same date each month. It is recommended (and most manufacturer guarantees require) that Sentinal be given year round, although some veterinarians may recommend giving it only during the mosquito season. If given seasonally, the first dose must be given within 30 days of the dog's first exposure to mosquitoes. The last dose must be given within 30 days after the dog's last exposure to mosquitoes.
To ensure complete absorption, always give Sentinel Flavor Tabs to dogs either with or immediately after a normal meal. Food is essential for proper absorption of lufenuron into the bloodstream.
Most dogs like the taste of Sentinel Flavor Tabs and will accept the tablet as a treat. As an alternative to a treat, they may be offered in food or given to your dog as you would other tablet medications. With either method of administration, the dog should also eat a whole meal. Watch the dog closely to be sure the entire dose has been consumed. If not entirely consumed, give another full recommended dose as soon as possible.
