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.

Sweet Mix for us!
By Nevillecreek on Aug 27, 2021
Somewhere, the dogs got a BAD case of worms. ALL of them. The vet recommended Sentinel. That was 8 years ago, and we are still using it every.single.month! We breed our dogs are very concerned about their health and well-being. Sentinel takes that worry off my plate, and autoship from Chewy makes it a solid bark for us, paws down!

By Kris on Aug 31, 2021
Like all Dogs one of my Dogs eats it and ask for more. The other spits it out 5 times before she finally gets it down. I don't think it the pill, she don't like much of anything but treats. the treat is hard which i found a little weird. other then that it seems to be doing it job.

It helps arthritis
By Tanzi 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

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.
