What are Heartgard Plus Chewables?

Heartgard Plus Chewables provide protection against heartworms, and treat and control roundworms and hookworms. These tasty chewables are made with real beef, making them easy to give your dog like a treat. Heartgard Plus Chewables are given monthly and require a prescription from your veterinarian.

For:

Dogs (6+ weeks of age, no weight requirement)

Benefits:

  • Effectively prevent heartworms
  • Treat and control roundworms & hookworms
  • Only given once a month
  • Delicious beef flavor makes them easy to administer

How do Heartgard Plus Chewables work?

Heartgard Plus Chewables contain ivermectin, a broad-spectrum antiparasitic medication used to prevent heartworms. They also contain 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:

Heartgard Plus Chewables may cause sensitivities in herding dog breeds. Heartgard Plus Chewables should be chewed, not swallowed whole. The chewables 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 Chewables every month, year round. Do not skip winter months, as your dog may become infected if left unprotected. If you miss more than two months of dosage, please consult with your veterinarian as to whether to continue medication.

Brand Name:

Heartgard Plus (Merial), Iverhart Plus (Virbac), Tri-Heart Plus (Intervet)

Generic Name:

Ivermectin, pyrantel pamoate

What is the most important thing I should know about Heartgard Plus Chewables?

The active ingredients in Heargard Plus Chewables are ivermectin and pyrantel pamoate. Use with caution, as 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 your pet is off Heartgard Plus Chewables 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. In addition, Heartgard Plus Chewables have shown a wide margin of safety at the recommended dose level in dogs including pregnant or breeding dogs, stud dogs and puppies aged 6 or more weeks.

What should I discuss with my veterinarian before giving Heartgard Plus Chewables 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 Chewables be given?

Give Heartgard Plus Chewables exactly as directed by your veterinarian. If you do not understand the directions, ask your pharmacist or veterinarian to explain them to you. Heartgard Plus Chewables must be chewed. They should not be swallowed whole.

What are the potential side effects of Heartgard Plus Chewables?

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

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

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

What happens if I overdose my pet on Heartgard Plus Chewables?

Seek emergency veterinary medical treatment.

What should I avoid while giving Heartgard Plus Chewables 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 your pet and in the household and to not feed your pet rodents or uncooked meat or fish. To prevent reinfection, daily cleanup of stools is recommended.

What other drugs will affect Heartgard Plus Chewables?

Do not give Heartgard Plus Chewables to your pet if he or she is already taking another heartworm medication.

Rated 5 out of 5 by from Keeps life simple! The option to give our dog one chewable a month and know he is covered makes our life so easy!!

Rated 1 out of 5 by from Doesn't work I've had my dog on the Plus version to prevent worms Well guess who had to go to the emergency vet for the bloody stool caused by worms She's been on the prevention form months and has never missed a dose. She was negative before we began treatment so she had to have contracted the worms ON her medicine. Of course I go to call the manufacturers and there is absolutely no way to contact them. I'm sick over this and so is my pup.

Yes, this medication is safe to give to your dog, as there is no weight limit. You will give the smallest dose of the blue box (up to 25lbs) once a month. Hope this helps.

My dog has food allergies. He is on a grain free and poultry free diet.  Can he take this medicine?

Asked by: Dawn2017
It is not certain what this product is made with, as the manufacturer does not list it. You may want to call the manufacturer for specific ingredients. These are beef flavored and do not contain poultry though, but they could be processed in a factory where other grain or poultry products were used. Hope this helps.
