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.

Fantastic customer service
By Angel on Sep 2, 2021
I just recently started buying our dog’s heart worm and flea prevention from chewy and it’s so great to be on their auto shipment. Auto ship assures me that nothing will be forgotten, and completely worry free. The customer service is top notch ready to help answer your questions anytime you call.

The best so far!
By Rachel on Jul 30, 2021
So, I have tried every over the counter flea medication and I have tried nearly all prescription flea pills. Very few worked at all . We had a very bad flea problem...even the house was full of them. This medication is WAY more affordable and it works!! They other prescriptions wouldn't last a month before she was covered in fleas again and Sentinel (so far) is doing the job!!! Also it has heart worm prevention and parasite prevention too. I am saving at least 30 a month..maybe alot more. You gotta get a 6 pack of this stuff....really it's the best!

So far so good
By Nisa on Sep 10, 2021
My dog took to the new medication fine. But my complaint is that my box arrived half opened. I inspected the inner portion to make sure it had not been tampered with and hope my auto ships will not arrive this way again.

Very Satisfied
By ButtersMom on Aug 19, 2021
My new vet doesn't carry Sentinel and Butters has taken it for years. Fast delivery. Safe shipping. Good price. Very satisfied.

Better prices than local vet, trusted source
By Mumof2 on Jul 9, 2021
We have used Sentinel exclusively for many years. Even with manufacturer rebates, Chewy offers better pricing and we don't have to worry about a knock off product.

Great Service from Chewy
By savedogs on Aug 5, 2021
Chewy got Doctors approval and shipped out quickly. Sentinel is a bit safer from my studies than other flea pills.

Do not buy this, as Spectrum (Virbac) does NOT stand behind their products!
By NanD on May 3, 2021
My dog began getting fleas, before the end of the 30 days, which caused her to get tape worms. Spectrum did nothing to help or refund any money! The only thing they did was waste my time, getting all my complaint info to turn into FTA, which they must do by law. Totally USELESS Company !!!!! Thank goodness for Chewy standing behind the products they sell!!

It was very very expensive
By ShaBags on Mar 22, 2021
I always get this prescription from you and you give me a discount. This time it was not available and my vet even said he could have sold me the sentinel tabs for less. I was disappointed and next time I will check my vets cost. I like you folks and have always purchased from you. I did not want to bother my vet. I am not giving you a 10 like I usually do. The rep said there are NO discounts on Sentinel and I know I had a much lower price in past and special.
