    What are Dog Heartgard Chewables?

    Heartgard Chewables are a flavored treatment for dogs given once a month to prevent heartworms. Heartgard Chewables require a prescription from your veterinarian.

    Looking to also control and treat roundworms and hookworms? Use Heartgard Plus Chewables.

    For: Dogs (6 weeks of age or older and no weight requirement)
     
    Benefits:
    Highly effective in preventing heartworms
    A convenient and tasty chewable for easy administration
    Delicious beef flavor that most dogs will eat

    How it works:
    Heartgard prevents heartworm disease by eliminating the tissue stage of heartworm larvae for a month after infection.

    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. For a full list of dog breeds that may be affected, click here.

    Cautions:
    Can cause sensitivities in herding dog breeds. It is important that you give your pet this preventative every month. If you miss more than two monthly doses, we recommend calling your vet before continuing the medication. Also, note that side effects are rare at the recommended heartworm prevention dose. Higher doses in dogs may cause tremors, dilated pupils, loss of body weight, and death. Side effects in cats include agitation, loss of appetite, staggering, dilated pupils, tremors, blindness and disorientation.


    More Information:
    Brand Name
    Heartgard Chewable (Merial)
    Generic Name
    Ivermectin

    What is the most important information I should know about Heartgard Chewable: Heartgard Chewable is a prescription medication available for dogs as beef flavored chewable tablets. The usual dose of Heartgard Chewable for dogs up to 25 pounds is 68mcg (blue box), for dogs 26-50 pounds is 136mcg (green box) and for dogs 51-100 pounds is 272mcg (brown box). The chewable tablets must be chewed and should not be swallowed whole. For dogs that normally swallow whole, the chewable tablets can be broken into pieces. 

    What is Heartgard Chewable: Heartgard chewable is given once a month for the prevention of heartworm disease in dogs. It is recommended by the American Heartworm Society that heartworm prevention be used year round. Heartgard may also be used for purposes other than those listed in this guide.

    What should I discuss with my veterinarian before giving Heartgard to my pet: Tell your veterinarian if your pet has ever had an allergic reaction to Heartgard, ivermectin, or to beef.

    How should this medication be given: Give Heartgard exactly as directed by the veterinarian. If you do not understand the directions ask the pharmacist or veterinarian to explain them to you. Heartgard 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 invermectin administered at elevated dose levels. Heartworm testing should be performed prior to the start of prevention therapy. If the animal is off Heartgard 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. Store Heartgard chewable at room temperature. Do not remove the chew from its wrapper until ready to give the medicine. Keep this medication away from children and pets. In addition, Dog Heartgard Chewables 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: Give the missed dose as soon as you remember. Do not give a double dose of the medication.

    What happens if I overdose the pet: Seek emergency veterinary medical treatment. Symptoms of overdose may include vomiting, diarrhea and lack of coordination in dogs.

    What should I avoid while giving Heartgard to my pet: To help with compliance and not missing a monthly dose, use the handy red heart reminder stickers included with the medication.

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

    What other drugs will affect Heartgard: Do not give Heartgard to your pet if already taking another heartworm medication.

    Where can I get more information: Your pharmacist has additional information about Heartgard written for health professionals that you may read.

    Our dogs love it! We have two dogs, one large & one small. Heartgard has always been our preference for heartworm preventative because every dog we've ever had will easily take these because they are apparently tasty, chewy and easy for them to eat & swallow. Other types of heartworm pills are harder for them to handle plus we have to hide other types of pills in human food and would often find them spit out somewhere in the house! With Heartgard we've never had this problem. Our only problem is that our vet doesn't offer these anymore and therefore we have to get written prescriptions & have them filled elsewhere. 11/19/2014
    easy to give I have a hard time getting Tony to take his meds. He loves the taste of the HG chewables. 11/07/2014
    I use to have a hard time getting my Peke to take his heartworm pill. Since I have been using Heartgard he is so excited every time I get the box out every month and gobbles it up as fast as he can! Thanks! 10/21/2014
    Gremlin loves these, So easy to give my Pom Heartguard chewables. He likes the flavor and eats them right up-like a treat. 10/12/2014
    Taste must be likeable. Pal takes his heartworm pill without any problem, but Buffy, my Yorkie, does not, and I have to break it up and hide it in a hot dog. Pal has been wearing a collar, very expensive, to help heartworms, but I am going back to the heartworm pill and no collar. He is presently on predistone for a yearly skin problem, causing problems for excessive urination and not making it outside. I am on the same medicine for a yellow jacket encounter-strange! 09/27/2014

    My dog weighs about 70 lbs and she got a hold of the heartworm package. There were about 4 or 5 pills left in there and she ate all of them.

    Answer: 
    According to manufacturer recommendations, the appropriate dose for a dog less than 5 pounds would be the blue dose (1-25lbs). Cutting a higher dose tablet in half may not provide accurate dosing for your pet.

    Answer: 
    No. Heartgard Plus already has dewormer in that formula. If you think your dog has worms you might get a vet check before giving another dewormer.
