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.
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.

Just like a treat!

Remus thinks these are a treat! I usually break them in half so that he can chew them easier. I've been using this brand for over a year and am happy with them!

Safer for Herding Breeds
By FurbabyMama on Jan 25, 2021
I chose Sentinel instead of ivermectin because herding breeds are sensitive to ivermectin and may have an allergic reaction that could cause death. I did not want to take the risk, so I have been giving my cattle dog Sentinel Spectrum for her whole life (7 years now). The product works just fine no heartworms, roundworms, and hookworms, flea populations, whipworms, and tapeworms. I am a satisfied HuMom.

Dog Likes Them
By ShadowSpaniel on Dec 2, 2020
Sometimes its hard to find something that the dog will eat without having to cover it with a pound of peanut butter... my dog loves these, and will eat them without a problem. They also do their job well, and I have never seen fleas on my dog since using this product, and he spends a lot of time out in the backyard, which backs up to a large field. Good product, I highly recommend.

Great Preventative
By HarleyATL on Nov 26, 2020
I’ve been giving this fir more than 1 year and I have not had a problem with heartworms or any gastrointestinal worms. My only problem is that Harley does not like it. She hasn’t from day 1. Pill pockets helped until they didn’t. I’m now using roasted chicken to disguise it. Clearly a terrible taste, but effective at its job, which is why I go through the monthly struggle.

A SOLUTION FOR ALLERGIC DOGS
By Linda on Sep 19, 2020
Sentinel Spectrum is the heartworm/flea medication my veterinarian recommended for my dog who is allergic to most everything. We had tried other products without success. Sentinel works and also comes in a pill form. She takes it year round and has never had a problem.

Best product
By bestlitter1 on Aug 1, 2020
This product has a different approach to fleas than normal and I love it. Instead of killing them immediately it prohibits them from reproducing. Which is honestly better in my opinion. You wont have to keep fighting fleas in your environment, if the fleas are bad in your area you can use this in conjunction with another flea product like bravecto. I like that sentinel spectrum has heart worm and intestinal parasite protection as well.

Easy Monthly Pill
By KCK90 on Jul 11, 2020
My boys have never had any real issues with fleas so I can't really speak to the flea prevention aspect. As a HW preventative it works as far as I can tell as we've had no issues. Only one of my dogs uses this brand and he happily accepts it.
