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.

Great product
By Goji on Dec 9, 2021
As a vet tech for decades, I can say this is my choice in parasite prevention for my dog. For those saying their dog still got fleas, This product does not kill or prevent fleas from getting on the dog. The medication in it simply prevents fleas from reproducing. So if you have fleas in the dog’s environment, you need to treat it with a secondary adulticide, as well as treat the environment. If there are no fleas in your dog’s home environment, but happens to pick one up while out on a walk or something, this product will help that or those fleas not turn into thousands. Environment control is a must. What fleas you see on your dog are only 10% of what in the actual environment.

Process Could Be Better
By VFL01 on Jan 5, 2022
I enjoy getting items shipped to home and the prices at Chewy BUT having to mail in the subscription/transcript for this is crazy to me. I don't understand why it can't be scanned or a picture taken and sent in. Have others really ruined it for those that are honest? All the hassle it took to figure out how to get these, I should have just gotten from my vet.

My dog’s choice flea and heart worm preventative pill
By Mary on Nov 18, 2021
With every dog I have ever owned, this is what I gave them. None of them have ever had fleas or heart worms. Unfortunately, this pill has been around for so long, it is outdated at the veterinarians office. I have to get a script in order to get it. Ordering with chewy was quick and easy. This was the first time I had ever used their pharmacy. I will continue to do so.

Did not work at all
By Fleas on Dec 19, 2021
Bought this for my four puts who are within the weight limit and it didn't work at all, if anything, seems like the fleas are worse. And they aren't even outside dogs.

garbage !!!
By ophelia on Nov 12, 2021
My vet prescribed this for my dog's flea problem. Its been three months (3 doses) and she still has a crazy amount of fleas. I kept waiting to see if each month's dose would build up and eventually work but nope!

Fast delivery

I have used Sentinel for our Jack Russells for over 25 years, this brand doesn't have the bad side effects as other heart worm RX does.

My dog still got fleas
By Livi on Oct 9, 2021
We used this product as instructed. My dog got a couple ticks, but I just chalked that up to a fluke. She then later got a flea infestation. Luckily we caught it early, but was very disappointed as I thought she was protected. We’ve switched to a Seresto collar and have been pleased.

You will love it too!
By Hookie on Aug 9, 2021
This medicine works great. I have used it for several years, the price is great much more affordable than the namebrands that do the same thing. My dogs have never gotten sick on this like the name brand makes them

Works Great
By Gina on Jul 15, 2021
Sentinel works great for our 13 year Yorkie mix. No side affects, and does the job! Chewy is super fast on getting the prescription approval from my vet and ships same day when they can. Highly recommend Chewy and Sentinel!
