Frequently Asked Questions

Q1: How do Sentinel Flavor Tabs protect my dog from fleas and worms?

Ans: Sentinel Flavor Tabs contain milbemycin oxime to prevent heartworms and intestinal parasites, and lufenuron to stop flea egg development. This dual action prevents heartworm disease, controls worm infestations, and breaks the flea life cycle by halting reproduction.

Q2: Can Sentinel Flavor Tabs kill adult fleas?

Ans: No, Sentinel Flavor Tabs prevent flea infestations by stopping eggs from hatching, but do not kill adult fleas. For existing infestations, veterinarians may recommend using an additional adulticide alongside Sentinel for full flea control.

Q3: When should I start giving Sentinel Flavor Tabs to my dog?

Ans: Treatment can begin at any time of year. In regions with seasonal flea or mosquito activity, start one month before the season begins and continue until it ends. In warm climates, use Sentinel year-round for complete protection.

Q4: What should I do if I miss a dose of Sentinel Flavor Tabs?

Ans: If a monthly dose is missed, give it immediately and resume the normal monthly schedule. Continuous monthly use is essential for full protection against heartworm disease and to maintain control of intestinal parasites and flea populations.

Q5: Are Sentinel Flavor Tabs safe for puppies and pregnant dogs?

Ans: Sentinel Flavor Tabs are approved for puppies four weeks old and weighing a minimum of two pounds. They’ve been tested as safe in breeding dogs and puppies when used as directed, but always check with your vet before administering to pregnant or lactating females.
