What is Heartgard Plus Chewables?

Heartgard Plus is a real-beef chewable tablet for dogs that provides protection against heartworms, and treats and controls roundworms and hookworms. Heartgard Plus is given monthly and requires a prescription from your veterinarian.

For:

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

Benefits:
  • Considered the most tasty heartworm chewable tablet (beef flavor)
  • Effectively controls heartworms, roundworms & hookworms
  • Only given once a month
How does Heartgard Plus work?

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.

Studies have indicated that certain dogs of the herding breeds are more sensitive to the effects of ivermectin administered at elevated dose levels due to the MDR1 gene. Dog breeds that may be affected include Australian Shepherd, Australian Shepherd Mini, Border Collie, Collie and English Shepherd.

Cautions when giving Heartgard Plus:

Heartgard Plus can cause sensitivities in herding dog breeds. Heartgard Plus chewable tablets should be chewed, not swallowed whole. The tablets may be broken into pieces and fed to dogs that normally swallow treats whole. Make sure that your dog eats the entire dose. It is important to give your dog Heartgard Plus every month year-round. Do not skip winter months as your dog may become infected. If you miss than two months of dosage, please consult with your veterinarian as to whether to continue medication.

What should I discuss with my veterinarian before giving Heartgard Plus to my pet?

Tell your veterinarian if your pet has ever had an allergic reaction to the medication, any of its individual ingredients, or to beef.

How should Heartgard Plus be given?

Give Heartgard Plus exactly as directed by the veterinarian. If you do not understand the directions ask the pharmacist or veterinarian to explain them to you. Heartgard Plus chewable tablets must be chewed. They should not be swallowed whole. Use with caution, Collies and other herding dog breeds have been known to have adverse reactions to ivermectin administered at elevated dose levels. Heartworm testing should be performed prior to the start of prevention therapy. If the animal is off Heartgard Plus for 6 months or less, start the medication and test after 6 months since microfilaria, that take 6 months to mature, will result in a positive test result. Store Heartgard Plus at room temperature. Do not remove the tablet from its wrapper until ready to give the medicine. Keep this medication away from children and pets. In addition, Heartgard Plus has shown a wide margin of safety at the recommended dose level in dogs including pregnant or breeding bitches, stud dogs and puppies aged 6 or more weeks.

What happens if I miss giving a dose of Heartgard Plus?

Give the missed dose as soon as you remember. Do not give a double dose of the medication.

What should I do if an accidental overdose of Heartgard Plus occurs?

Seek emergency veterinary medical treatment.

What should I avoid while giving Heartgard Plus to my pet?

Because humans can contract hookworm from animals, it is important to maintain good personal hygiene. It is also important to eliminate fleas on the pet and in the household and to not feed the pet rodents or uncooked meat or fish. To prevent reinfection, daily cleanup of stools is recommended.

What are the possible side effects of Heartgard Plus?

Side effects of Heartgard Plus are rare at the recommended heartworm prevention dose. Higher doses in dogs may cause tremors, dilated pupils, and loss of body weight and death.

Rated 1 out of 5 by from DO NOT BUY Not happy with this product at all. I got my dog at a rescue and as I do for all my rescue dog I had a basic blood panel done which included a heartworm test. My dog tested negative. One year later after giving him Heartguard faithfully for the entire year he developed heartworm. No help from Heartguard with the costly treatment. All I get is a years worth of Heartguard free. Whopper!!!! I will never give my animals Heartguard again. EVER!!

My Yorkie/Maltese is 5lbs, do I give him the full dose of the up to 25lbs chewable

Asked by: Stacey
Yes, give your dog the entire chewable tablet. It is proven safe at that dose and to only give part of the chew tab is risky as the medication may not be evenly spit in the tablet leading to potential under-dosing.

My dog was recently diagnosed with heartworms. The vet prescribed heartgard. Since it is a preventative, I wonder how it will help of he has what it prevents?

Asked by: Hector
Your vet has opted to not kill the adult heartworms but is instead preventing further infection with the use of a prevention. The adult worms your dog has will die off gradually over the next couple of years. There are risks with this method as well as with killing the adults directly so you may want to talk to your vet about his/her decision to set your mind at ease.

My one year old dog just recently reached 50 lbs.  I picked up,his Heartguard Plus dose and when I went yo give it to him, it was for 50-100 lbs.  Is this safe? The vet tech said he should go to the next size.  I am still feeling unsure.

Asked by: Samm
You have been given the proper dose for your dog especially since he is just a year old and will likely gain a little more weight.

I have An 8 month old mini Australian Shepard. And need heart worm meds but all these are saying need prescription of doctor and may be harmful to my breed

Asked by: Tiffany46
You need a veterinarian's prescription to purchase any heartworm prevention. Collie-type dogs may carry a gene that causes them to be sensitive to ivermectin. I would recommend a heartworm prevention that does not contain ivermectin, such as Interceptor Plus, Trifexis or Advantage Multi.
