Heartgard Plus Chewable for Dogs - Heartworm Prevention

Heartgard Plus is the #1 vet-recommended heartworm prevention for dogs. It eliminates the tissue stage of heartworm larvae and also treats and controls intestinal worms like hookworms and roundworms. Heartgard Plus is formulated in a soft, tasty, real-beef chewable, and is accepted easily by all dogs.

Heartgard Plus helps safeguard canines from harmful heartworm disease and intestinal infections. This oral heartworm treatment is recommended for dogs and puppies 6 weeks of age and above. Heartgard Plus chewables should be given regularly at an interval of one month for continuous protection. The oral treatment is safe for stud dogs, pregnant, breeding, and lactating dogs.

How Heartgard Plus works?

Heartgard Plus contains two key ingredients: ivermectin and pyrantel pamoate. Ivermectin prevents heartworm disease by killing the immature stage (larvae) of heartworms (Dirofilaria immitis), hence, preventing them from developing into adult heartworms for 30 days. The other ingredient, pyrantel pamoate, treats and prevents intestinal worms – roundworms (Toxocara canis, Toxascaris leonina) and hookworms (Ancylostoma caninum, Uncinaria stenocephala, Ancylostoma braziliense) in dogs. Regular use of Heartgard Plus may also help to reduce the burden of roundworm eggs and hookworm larvae in the environment, and thereby reduce the risk of reinfection.

Nuheart : Generic - Heartgard for Dogs

Nuheart is the generic version of Heartgard. It is a well-known heartworm preventive for dogs. The oral monthly treatment offers three-way delivery system. Nuheart has the same ingredients as Heartgard therefore it is as effective as the branded heartworm preventive. The meat flavored heartwormer contains Ivermectin – the same ingredient is present in Heartgard. The monthly treatment prevents heartworms and protect dogs against heartworm infection. The small in size flavored tablet is easy to administer and is highly palatable.

Nuheart is safe for puppies as young as 6 weeks of age.

Important Note: Merial is now acquired by Boehringer Ingelheim. So, the manufacturer’s name on product packs may vary according to the available stock.

How to Use Heartgard Plus for Dogs

Heartgard Plus tablets are chewable, so very easy to administer.  Just offer one tablet every month by hand (whole or broken) or alternatively mix it with the dog food. Only make sure your dog chews the tablet and does not swallow it.

  • Some dogs, especially Collies and other herding breeds are more sensitive to ivermectin if given an overdose.
  • Side effects are rare but may include vomiting, diarrhea and drooling, especially in case of overdose. Consult your vet if signs persist.  

Caution:Collies including Border Collies and other breeds are sensitive to Ivermectin. Please consult your vet before giving this treatment or look for alternatives to Ivermectin for the treatment of parasites.
