How are Sentinel Spectrum and Sentinel Flavor Tabs different from other heartworm medications?

Not all heartworm medicines provide the same spectrum of parasite protection. Sentinel Flavor Tabs are chewable tablets that protect dogs against fleas, heartworms, roundworms, hookworms, and whipworms. Sentinel Spectrum is a soft, beef and bacon flavored chew that adds tapeworm protection to offer the broadest coverage available.

My dog weighs more than 100 pounds. Are Sentinel Specturm or Sentinel Flavor Tabs a good option for him?

Yes. Talk to your veterinarian about the appropriate dose for your pet.

My dog is a toy breed. Are Sentinel Specturm or Sentinel Flavor Tabs okay for his small size?

Yes. Both Sentinel Specturm and Sentinel Flavor Tabs offer a size that can be given to small dogs. Sentinel Spectrum has a size available for dogs weighing from 2–8 lbs and Sentinel Flavor Tabs has a size available for dogs weighing from 2–10 lbs.

I see a few fleas on my dog. Is the medication working?

You may see an occasional “hitchhiker” adult flea that your dog has picked up at the dog park or in the yard or other infested environments where 95% of the flea population lives in the form of eggs, maggot-like larvae, and pupae. Sentinel Specturm and Sentinel Flavor Tabs put an end to fleas before they become adults. You may need an adulticide, such as Effitix Topical Solution for Dogs, to treat occasional adult fleas.

Can I give either Sentinel Spectrum or Sentinel Flavor Tabs to my cat?

No, both Sentinel Spectrum and Sentinel Flavor Tabs are only approved for use in dogs.
