Precautions
All dogs should be tested for existing heartworm infection before starting treatment with Tri-Heart Plus, which is not effective against adult D. immitis. Infected dogs must be treated to remove adult heartworms and microfilariae before initiating a program. Tri-Heart Plus is not indicated for dogs younger than 6 weeks old. Herding breeds (such as Collies) can be sensitive to the active ingredient, so talk to your veterinarian if your dog may be affected. If you miss a dose, your dog needs a blood test to resume your normal doses safely. Notify your veterinarian if you've skipped a dose or have any concerns. Keep this and all drugs out of the reach of children.

Is Tri-Heart Plus safe for my dog?
Tri-Heart Plus flavored chewable tablets are an FDA-licensed product, indicating they are safe and effective when used as recommended on the label. All dogs should be tested for existing heartworm infection before starting treatment with Tri-Heart Plus.
My dog is taking some other medications for another condition. Is it still safe to give her Tri-Heart Plus tablets?
In clinical trials, many commonly used flea collars, dips, shampoos, anthelmintics (deworming medications), antibiotics, vaccines and steroid preparations have been administered with ivermectin/pyrantel in a heartworm disease prevention program. For questions about specific medications, please consult your veterinarian.
Is it okay to give my pregnant dog Tri-Heart Plus tablets? What about after she has given birth and is breastfeeding the puppies?
Ivermectin/pyrantel, the active ingredients in Tri-Heart Plus, have a wide margin of safety at the recommended dose level in dogs, including pregnant females, breeding males and females, and puppies 6 weeks or older, according to the package insert.
Can Tri-Heart Plus tablets be given to a dog that has heartworms or that is heartworm-positive?
No. Tri-Heart Plus is labeled for use in dogs to prevent heartworm disease and not for the treatment of heartworm infections. The package insert contains this precautionary statement: “Infected dogs must be treated to remove adult heartworms and microfilariae before initiating a program with Tri-Heart Plus flavored chewable tablets.”
Can Tri-Heart Plus be used as a heartworm preventive in cats?
No. Tri-Heart Plus is not approved for use in cats.
Our dog's Tri-Heart Plus flavored chewable tablets expired last month. Is it still okay to give her Tri-Heart Plus tablets after their expiration date?
Medications, including Tri-Heart Plus, should never be administered after the expiration date. Studies have shown that Tri-Heart Plus will maintain its desired effectiveness when administered prior to the expiration date, when stored as recommended on the label.
My dog weighs less than 10 lbs. Should I give him the whole tablet even though it says for dogs up to 25 lbs?
Yes. The entire tablet should be administered as a single dose once each month. The smallest-sized Tri-Heart Plus tablet, in the blue-colored packaging, is labeled for dogs weighing 25 lbs or less. These tablets are scored to make it easier to break the tablet apart and have the small dog take the complete tablet but in smaller pieces at a time. Regardless of whether the tablet is broken apart or given the whole, the entire tablet should be given as a single dose.
Is it okay to give my pregnant dog Tri-Heart Plus tablets? What about after she has given birth and is breastfeeding the puppies?
Ivermectin/Pyrantel, the active ingredients in Tri-Heart Plus, have a wide margin of safety at the recommended dose level in dogs, including pregnant females, breeding males and females, and puppies 6 weeks old or more according to the package insert.
I accidentally gave my dog his Tri-Heart Plus tablet after my husband had already given one to him. Will he be okay?
Contact your veterinarian immediately if accidental overdose occurs. To reduce the risk of accidental overdose in situations where more than one person may administer Tri-Heart Plus, we suggest ticking off the date on a specially marked calendar or making some other note to indicate that the dose has been given. Make a habit of checking with the other pet caregivers in your household before giving any medications to your pet.
My dog is taking some other medications for another condition. Is it still safe to give her Tri-Heart Plus tablets?
In clinical trials, many commonly used flea collars, dips, shampoos, anthelmintics (deworming medications), antibiotics, vaccines, and steroid preparations have been administered with ivermectin/pyrantel in a heartworm disease preventive program. For questions on specific medications, please consult with your veterinarian.
I forgot to give my dog his Tri-Heart Plus medication last month. Is he still protected? What should I do?
If the interval between doses exceeds 30 days, the efficacy of ivermectin can be reduced. Therefore, for optimal performance, the chewable tablet must be given once a month, on or about the same day of the month (Sign up for our email reminder service). If treatment is delayed, whether by a few days or many, please contact your veterinarian, as immediate treatment with Tri-Heart Plus chewable tablets and resumption of the recommended dosing regimen minimizes the opportunity for the development of adult heartworms.
Where can I buy Tri-Heart Plus tablets?
Tri-Heart Plus flavored chewable tablets can be obtained by prescription only and are available from your veterinarian.
Is Tri-Heart Plus safe for my dog?
Tri-Heart Plus flavored chewable tablets are an FDA-licensed product, indicating that they are safe and effective when used as recommended on the label. All dogs should be tested for existing heartworm infection before starting treatment with Tri-Heart Plus.
How long will the Tri-Heart Plus tablets last once removed from the blister pack?
The blister package is designed to protect the tablets from exposure to air and light. Therefore a tablet should be administered at the time it is removed from the blister foil. Also if the blister or foil is not intact (for example the foil is peeled back or there's a hole in it), the tablet should not be used.
Do Tri-Heart Plus tablets contain wheat or rice gluten?
No.
Where can I find additional information about heartworms?
The American Heartworm Society (AHS) is an excellent source of information for both pet owners and veterinarians.

Great price, does great for my dogs!
By Casey on Jan 10, 2022
With several big dogs, the shots and other heartworm preventions become very costly. The dogs have to have heartworm prevention but it does not have to be terribly expensive! Tri-Heart is affordable and does the same thing as brands that are more expensive. I broke up the large pill and my dogs ate the pieces with no problems. No side affects from my seniors either! Great product, will be ordering again.

round worm
By JB10 on Dec 15, 2021
Been giving my dog this product for a year now and didn’t have a issue till recently. Product says it’s supposed to protect against heart worm, hook worm, and roundworms. But at the vet recently my dog had roundworm eggs in her fecal matter. Seems to work for heartworm but wouldn’t recommend to protect against all 3.

My dog loves them!!
By Alex on Dec 3, 2021
My dog will eat pretty much anything that doesn’t eat him first, but he hates pills (I always have to coat them in cheese or peanut butter). The tri-heart chewable tablets however, he absolutely loves. He gobbled them right up! Plus, they’re much cheaper than what the vet sells and seem to be just as effective.

Tri - heard plus chewable tablets
By Becky on Oct 9, 2021
Just as good as the more expensive brands and cost considerably less. Actually my German Shepard’s must have liked the taste better too because unlike the more expensive brand I used before , they ate it right up with no problems.

Very Relieved
By LadyCop on Oct 9, 2021
Was very nervous that my really picky Great Pyrenees would not like the tablet but she ate it right up! I'm definitely converted from over priced Heartgard

Great product
By Tiff on Jul 26, 2021
I generally buy heartguard plus or intercepter plus..however the prices for the medications are a bit on the high end. So I chose triheart plus this time around and it's basically the same as heartgard plus anyway the difference is triheart is a beef flavored tab chew and heartgard is a beef soft chew. But this doesn't stop my pup from chewing it up like a dog treat he still loves to eat these.
