Sentinel Spectrum Chew for Dogs, 2-8 lbs, (Orange Box)
Prescription Item
Oops! Something went wrong. Please try again.
Your furry friend must have a current heartworm test result on file with your veterinarian in order to be prescribed heartworm medication. Please visit your veterinarian to have this test performed annually to protect your four-legged friend. Sentinel Spectrum is a monthly oral preventive prescription that protects your pet against heartworms, adult roundworms, adult hookworms, whipworms, and prevents the development of flea eggs. Best of all, this medication may also help protect your pal against heartworm disease and intestinal worms, all in a tasty, flavored chewable tablet.
Proudly sourced directly from the manufacturer or their approved distributor. Guaranteed genuine and backed by the manufacturer.
UsesSentinel Spectrum is indicated for the prevention of heartworm disease. It is also formulated to help prevent and control flea populations, and for the treatment and control of adult roundworm, hookworm, whipworm, and tapeworm infections in dogs and puppies six weeks of age and older and weighing at least two pounds.
Possible Side EffectsThe following adverse reactions have been reported in dogs after administration of milbemycin oxime, lufenuron, or praziquantel: vomiting, depression/lethargy, pruritus, urticaria, diarrhea, anorexia, skin congestion, ataxia, convulsions, salivation, and weakness.
Drug & Food InteractionsThere are no known contraindications to the use of Sentinel Spectrum.
Precautions
Treatment with fewer than 6 monthly doses after the last exposure to mosquitoes may not provide complete heartworm prevention. Prior to administration of Sentinel Spectrum, dogs should be tested for existing heartworm infections. At the discretion of the veterinarian, infected dogs should be treated to remove adult heartworms. This medication is not effective against adult D. immitis. Mild, transient hypersensitivity reactions, such as labored breathing, vomiting, hypersalivation, and lethargy, have been noted in some dogs treated with milbemycin oxime carrying a high number of circulating microfilariae. These reactions are presumably caused by release of protein from dead or dying microfilariae. Do not use in puppies less than six weeks of age. Do not use in dogs or puppies less than two pounds of body weight. The safety of this medication has not been evaluated in dogs used for breeding or in lactating females. Studies have been performed with milbemycin oxime and lufenuron alone. Not for use in humans. Keep this and all drugs out of the reach of children.

2.3 mg Milbemycin Oxime, 46 mg Lufenuron and 22.8 mg Praziquantel.
Sentinel Spectrum should be administered orally, once every month, at the minimum dosage of 0.23 mg/lb (0.5 mg/kg) milbemycin oxime, 4.55 mg/lb (10 mg/kg) lufenuron, and 2.28 mg/lb (5 mg/kg) praziquantel. For heartworm prevention, give once monthly for at least 6 months after exposure to mosquitoes.
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.

Very Pleased
By LUV1831 on Oct 16, 2021
Our Fur Son ITTY-BITTY only 6 lb (A MORKIE) we started him on Sentinel at his second vet appointment he's been on it ever since and he will be 1 on the 27th of this month I think Sentinel is awesome it works extremely well although he doesn't go outside at all unless he's unless it's appointments and when he does he's constantly his stroller therefore he doesn't be around dogs so I don't have to worry about the flea part but this does work apparently well against fleas as well he does not like it by itself so we literally always have to crush it up in little pieces to camouflage it with his wet food what they said I definitely recommend this product this will be my second 6 month supply

So easy to use!
By Nayster on Jul 14, 2021
This product is so easy to use and works very well. Much better than the topical flea medicine. My 3lb. Yorkie gobbles them up each month without having to "hid" it in cheese!

One of the better ones
By Biewers on Jun 30, 2021
Great for small dogs that mostly stay at home. A bit hard for them to chew. Not a great flavor!!

As expected

Was a little worried about ordering his medication online that it might be close to expiration date or expired. But dates were fine abc it was genuine product.

Excellent Service
By Debbie on Dec 7, 2020
Chewy takes responsibility to obtain Rx from the vet and then ships. Great service especially when your vet is not relatively close. Keeps you informed of the status of your order. Great customer service.

Convenient!
By Dutchess on Aug 5, 2020
We have used Sentinel Spectrum for 4 years now for my Pomeranians and Frenchie. Very convenient and I haven't noticed any side effects. The only down side is the price has jumped up almost double but still worth the price. I love Chewy they are so helpful when filling my dogs Rx

Husbands a chemist and looked into all sides effects before buying this.
By Florence on Mar 22, 2020
Just started using it and no side effects for out small girls. We used bravecto as directed by our Vet and the puppies weren’t looking good for a few days and had diarrhea also one had some aggression. It looks like it’s calming the demodex eye mites one has. We tried bravecto and they’ve come back again. So hopefully keeping up with this will do the trick.
