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.
Store in a dry place at controlled room temperature between 59° - 77°F.

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.
No, both Sentinel Spectrum and Sentinel Flavor Tabs are only approved for use in dogs.
I have been using this Sentinel product on all my dogs for 25 years! Seven dogs total (with two currently using) and none have ever tested positive for heartworm disease or parasites & have never had fleas. I used to wrap the table in cheese, but with current two I crush it & mix it in a meal. The best product I have ever used and will continue to use. It is also cost effective which is a plus!
This is the perfect product to keep your pup healthy have used this for multiple dogs over the years with no problems. Once a month and you have a happy healthy pup.
Glad to have the medicine available for Riley. I will be away and I give it a him the first of the month. I don’t want to scramble and or miss.
This is the same Sentinel my vet prescribes for my Husky except it's $40 less for a year's supply at Chewy. I had some questions about the product so I called customer service. Extremely nice and very accommodating!
My dog is still getting lots of flea bites. Maybe a few less than before the medication, but I was expecting complete flea control. Disappointed.
After using this med for 17 yrs on all of my dogs, something has changed! I couldn’t figure out what was going on with my pup last Dec, but something was wrong! Took him to the vet and was totally floored to find out my pup was allergic to what my vet called “baby fleas!” It was freezing outside! Where would an inside dog, who only goes out to potty, get fleas in subzero temps? He had been taking Sentinel for over 4 yrs and never had a flea issue before! Either the fleas developed a resistance to the med, or something has changed with the med! Switched him to a different med, which is much more expensive, but that solved the problem!
easy to use, no problems with refusal from the dog no side effects good product....
Product arrived quickly but was disappointed that manufacturer wouldn't allow rebate because purchased online.
Vet recommended. So far so good. Excellent rebates when purchased in conjunction with other Merck Animal Health products. However, as I just learned, Merck will not honor rebates for product purchased from Chewy. Merck is adamant. Chewy told me to talk to Merck. Good bye rebate.
I have been buying this since 1997 for all of my dogs to protect against Heartworm and fleas. Its easy, works great and I have never seen one flea....
