23 mg Milbemycin Oxime and 460 mg Lufenuron.
Sentinel Flavor Tabs are given orally, once a month, at the recommended minimum dosage of 0.23 mg/lb (0.5 mg/kg) milbemycin oxime and 4.55 mg/lb (10mg/kg) lufenuron. To ensure adequate absorption, always administer immediately after or in conjunction with a normal meal.
The chewables should be administered in a manner that encourages the dog to chew, rather than to swallow without chewing. Chewables may be broken into pieces and fed to dogs that normally swallow treats whole. Care should be taken that the dog consumes the complete dose, and treated animals should be observed a few minutes after administration to ensure that no part of the dose is lost or rejected. If it is suspected that any of the doses have been lost, redosing is recommended.
Heartworm Prevention: Sentinel Spectrum should be administered at monthly intervals beginning within 1 month of the dog’s first seasonal exposure to mosquitoes and continuing until at least 6 months after the dog’s last seasonal exposure. Sentinel Spectrum may be administered year-round without interruption. When switching from another heartworm preventative product to Sentinel Spectrum, the first dose of Sentinel Spectrum should be given within a month of the last dose of the former product.
Flea Treatment & Prevention: Treatment with Sentinel Spectrum may begin at any time of the year, preferably starting one month before fleas become active and continuing monthly through the end of flea season. In areas where fleas are common year-round, monthly treatment with Sentinel Spectrum should continue the entire year without interruption. To minimize the likelihood of flea reinfestation, it is important to treat all animals within a household with an approved flea protection product, as necessary.
Intestinal Nematode & Cestode treatment and control: Dogs may be exposed to and can become infected with roundworms, whipworms, hookworms, and tapeworms throughout the year, regardless of season or climate. Clients should be advised of appropriate measures to prevent reinfection of their dog with intestinal parasites. Because the prepatent period for E. multilocularis may be as short as 26 days, dogs treated at the labeled monthly intervals may become reinfected and shed eggs between treatments.
Storage InstructionsStore in a dry place at controlled room temperature between 59° - 77°F.
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.

It helps arthritis
By LWmi on Apr 15, 2021
My 10 year old catahoula mix was diagnosed with arthritis about three months ago. She was having a lot of trouble getting up, going up stairs and walked very slowly. It seemed like it happened suddenly, but the Dr said the x-rays showed bad arthritis, so I guess it must be. I am too scared to give Cox inhibitors due to the possibility of liver or kidney damage, but my girl weighs 110lb and so I have to keep her walking on her own as long as possible. Galliprant has these potential side effects too, but it works further down the chain than the Cox enzymes, inhibiting one called E4. This is more specific and can help maintain the mucosal lining of the digestive system better than inhibiting My 10 year old catahoula mix was diagnosed with arthritis about three months ago.

This is more specific and can help maintain the mucosal lining of the digestive system better than inhibiting Cox enzymes. She has been taking it for one month, then a two month pause, now six weeks more. She is able to get up a little more easily, as long as she doesn't have too much activity. She also is able to put a little more weight on her right back leg, which is the worst one. It's not like she is now running around, but she is no longer limping on her front legs, which apparently were taking most of her weight before the drug. At first she had some signs of acidy stomach a few hours after taking it but not now. I just wish it were more affordable. The literature shows it is more effective on an empty stomach, but that was not on the label when I got it. Disclaimer: I am not a doctor and did my own research, so everyone needs to make their own decisions not just based on my information. If you use it, get a baseline kidney and liver test and then monitor as recommended by the Dr. … more

Fast, easy, and convenient
By Wendi on Jun 14, 2021
Sentinel is a great product. I love getting prescriptions through Chewy because they are delivered quickly and convenient to order without a trip to the vet.

Always a good price
By Hambone on May 14, 2021
I don't get a ton of stuff on line. But Chewy's prices are always good and I usually get free shipping. My boys(English Bulldog and Golden Retriever) do miss the treat they use to include with the purchase.

So easy and so fast!
By AlaynaW on Jun 13, 2021
So easy and so fast! Chewy got in touch with my veterinarian on their own and made this whole process very easy and convenient for us!

Never Had a Problem
By DeDee34 on May 27, 2021
My black lab has been on Sentinel for 5 years and has never had a problem with ticks or fleas as well as heartworms. She loves taking it with peanut butter!

Great Price. Great Service
By Karen on May 21, 2021
This was the first time we’ve ordered meds from Chewy. Excellent price and excellent service — will switch all Riley’s meds as well as our cat’s meds to Chewy

Great stuff!
By Hemi on Apr 7, 2021
I gave this to my previous dogs. My current 8 year old dog has used this her entire life. This product has been around for a long time and is very reliable. I tried brovecto once and it made my dog extremely ill. Never again will I stray from this reliable sentinel!

These pills are great
By Betty on Mar 26, 2021
I've been using these pills for years for my dogs, once a month. They are huge though and so I pound them into powder before cutting open the foil wrapper, and mix them with the wet dog food. My German Shepherd Chiara, who thinks she is a whole lot smarter than me, never notices there is a PILL in her bowl.

Doesn't actually control fleas - read the fine print!
By BassetMum on Feb 10, 2021
My dog has very sensitive skin which reacts terribly to fleas, and doesn't do well with topical treatments. So I thought this product would be a good option to combine flea control with heartworm prevention. I was wrong. Granted, the fine print does state that this product affects flea eggs (as opposed to adults) and that an adulticide may also be needed, but the manufacturer's advertising message is misleading. My poor dog got fleas despite being on this medication, and I needed to treat him with additional top-spot flea medicine which defeated the purpose (and additional expense) of this "combination" product. I have cancelled my auto-replenishment and will ask my vet for a different heartworm My dog has very sensitive skin which reacts terribly to fleas, and doesn't do well with topical treatments.

Sentinel Tablet
By Annie on Apr 17, 2021
I have been using this product for my dog for over a year. She has remained Heart worm free, tick and flea free. It totally amazes me how quickly chewy can process orders and deliver the order.
