Sentinel Spectrum Chew for Dogs, 50.1-100 lbs, (Blue 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 guards against heartworms, adult roundworms, adult hookworms, whipworms, and prevents the development of flea eggs. It protects your dog against heartworm disease and intestinal worms, all in a palatable, beef-flavored chewable.
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.

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.

Love what it does, dog hates it
By HaleyHank on Sep 12, 2021
I’ve always combined sentinel with bravecto since working at a vet clinic and it’s always been the best combination, but my dog refuses to eat both of them and I swear he can sniff these chews out in ANYTHING. Won’t sniff out the five medications he’s on in pill pockets or wet food, meat, etc but he’s a sleuth with these. Wish they were more appealing but I can understand it is a medication so you can only do so much. Took one star just for the monthly battle of blehing the chew in the floor and the struggle to pill a 100 pound dog that follows.

Monthly care
By Blue on Oct 10, 2021
I have used Sentinel on both of my labs. Our first lab Max used it for 14 years, and my current lab Blue for the last 5 years. They have been flea and heart worm free! I love the auto ship convenience, I never have to worry about Blue missing his monthly treatment!!

Best out there
By GunterandMoose on Sep 13, 2021
When I got my first rescue, the humane society gave me a free vet visit where I got one of the Chews from for the first time. It has not been a year since I got Gunter. Because of the chews Gunter is heart worm free and has never gotten fleas. Now with my newest rescue, Moose, I also give him these. I 100% back this company.

Sentinel Spectrum
By Trish on Aug 19, 2021
I used Sentinel Spectrum for many years for my previous dogs. There re others in the form of a chew, but my dogs could always detect the scent and spit them out. This is the only product they would willing take. When I got my new pup, it made sense to put her on the same regimen. My vet hospital does not stock this product, but it is available on Chewy and other websites. I love Chewy's customer service! I called me vet who mentioned them as an option. After I place the order, they did the rest and got it to me well ahead of when the next dose it needed. Thanks Chewy!

Works Great When Paired Wirh Vectra 3D
By dogmomma94 on Jul 16, 2021 top1000Contributor
I use Sentinel Spectrum and Vectra 3D for my babies and we’ve never had an issue. Alone they aren’t as effective. Together they repel and kill almost everything. Kills and repels 4 different ticks, repels mosquitoes, biting flies, mites, all life stages of fleas, heart worms, hook round tape and whip worms. And with this combo, ticks don’t even have to bite for the medication to kill them so less of a worry of tick borne diseases. I was using Revolution but my German Shepherd ended up with Lyme disease because that particular medication only does one tick and unfortunately it isn’t even the one that carries Lyme. Would recommend this combo to any pet owner! Peace of mind is priceless.

Unbeatable Price for the Amount in the Package
By DogMom on Aug 26, 2021
My dog hates pills... and I mean he will personally pick them out of his food and eat around them in order not to eat it. I have to cut this into pieces for him to eat but surprisingly he is very good about eating this one. I love that I can go on chewy and purchase these rather than at the vet because the price is a bit cheaper.

Sentinel chews
By Kipsperson on Jul 28, 2021
My person used sentinel tablets in the past because they really worked keeping those creatures off me and free of heartworms (have you ever seen a picture of a heart full of long white worms? Ewwwwww it's so gross!). I got really tired of my person shoving them down my throat after I licked all the flavor off. So, now she doesn't give those to me anymore, she just gives me a "treat". She thinks she has me buffaloed, but I know the deal!

Improvement
By Buster on May 23, 2021
My 3 year old bulldog's prescription for heartworm medication had run out so I got a vet to send in another for him. After not hearing from chewy for a couple of weeks I called. The nice woman on the other end checked with the pharmacy to see what the problem was. Evidently because the script was for 50 to 100 pounds rather than 25 to 50 poubds they wouldn't fill it. It is not unusual for a 3 year old bulldog to weigh over 50 pounds...dogs grow.

Hands down BEST
By KC0112 on Jun 25, 2021
I love pairing this with NexGard! Between the two, both of my pups are covered from all creepy crawlies. My pittie is not a huge fan of these, but I just wrap them up with a small piece of food and he eats it with no problem!
