Heartgard Plus Chewables for Dogs 51 - 100 lbs Brown - 12 Pack

What is Heartgard Plus?

 Heartgard Plus Chewables is a monthly meaty chew used for the prevention of heartworm disease and for the control of roundworms and hookworms in dogs.


Dogs (6 weeks of age or older and no weight requirement)


• Considered the most tasty heartworm chewable tablet (beef flavor)
• Effectively controls heartworms, roundworms & hookworms
• Only given once a month

How it works:

Heartgard Plus contains ivermectin, a broad-spectrum antiparasitic medication used to prevent heartworms. Heartgard Plus also contains Pyrantel Pamoate, an anthelminthic, used to prevent roundworms and hookworms.



Directions for Use

Heartgard (Ivermectin) is given once a month year round for the prevention of heartworm disease. The usual dose of ivermectin in dogs up to 25 lb is 68mcg – 1 tablet from blue pack, for 26-50 lb is 136mcg – 1 tablet from green pack and for 51-100 lb is 272mcg – 1 tablet from brown pack.  Dogs over 100 lb are given a combination of the tablets.


This medication should not be used in animals allergic to it. Heartworm testing should be performed prior to the start of prevention therapy. If the animal is off ivermectin for 6 months or less, start the medication and test after 6 months since microfilaria, which take 6 months to mature, may result in a positive test result.

Possible Side Effects

The side effects of ivermectin are rare at the recommended dosage. Heartgard Tablets has a wide margin of safety for all sizes and breeds of dogs. It is approved for use in puppies as young as 6 weeks, small dogs regardless of weight, pregnant or breeding bitches, stud dogs, and Collies.

"Came back to Heartgard"

Our local vet stopped carrying Heartgard and gave our Emme another brand. We noticed the first time we dosed her that she was "off her feed" for a day but seemed fine otherwise. The next month she took the dose, but within 45 minutes she vomited several times and began acting VERY lethargic. We rushed her to our vet where she was diagnosed with an allergic reaction. She was treated accordingly and recovered her appetite and pep a day or two later. Our vet blamed a new rawhide chew instead of the heartworm treatment stating that all heartworm meds pretty much contain the same ingredients. In our opinion the inactive fillers in the medicine which made it crunchy instead of chewy may vary widely and this could have been what she reacted to. We returned to Heartgard through PetMeds and our dog had absolutely no problem this month when we dosed her. She has also ingested more of the rawhide chew in question with no bad results. We will stay with the Heartgard Chewables.
