Frequently Asked Questions

Q1: What does Sentinel Flavor Tabs for Medium Dogs protect against?

Ans: Sentinel Flavor Tabs for Medium Dogs protect against heartworm disease, roundworms, hookworms, whipworms, and flea populations by preventing flea eggs from developing. This monthly tablet provides broad-spectrum protection and helps keep dogs safe from multiple internal and external parasites.

Q2: Do Sentinel Flavor Tabs kill adult fleas on dogs?

Ans: No, Sentinel Flavor Tabs do not kill adult fleas. Instead, they contain lufenuron, which prevents flea eggs from hatching. For dogs with visible fleas, an additional approved adulticide should be used alongside Sentinel to eliminate adult fleas.

Q3: Can I give Sentinel Flavor Tabs to my puppy?

Ans: Yes, Sentinel Flavor Tabs can be given to puppies that are at least four weeks old and weigh two pounds or more. Always follow the correct dosage instructions and consult your veterinarian before starting treatment for young or small-breed puppies.

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

Ans: If you miss a dose and more than 30 days have passed, administer Sentinel Flavor Tabs immediately and then continue with regular monthly dosing. Skipping doses can reduce protection against heartworms and fleas, so maintaining consistency is essential.

Q5: How should I give Sentinel Flavor Tabs to my dog?

Ans: Give Sentinel Flavor Tabs orally immediately after or with your dog’s regular meal. Ensure your dog swallows the full tablet for proper absorption. Most dogs find the flavored tablets palatable, making administration simple and stress-free.
