Always follow your veterinarian's prescription. Dosing for pets differs significantly from human dosing even for the same medication. Never administer a human dose to your pet without veterinary guidance.

Frequently Asked Questions
Does Sentinel kill adult fleas?
No — Sentinel breaks the flea life cycle but does not kill adult fleas. For active infestations, add an adulticide like NexGard. Discuss combination with your vet.
