    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.

    Perfect ! I like the Heartgard Chewables because it's just Ivermectin ~ no other medication added. Plus she doesn't get sick on this med. 07/23/2014
    I have 3 dachshunds and have used this for 8 years. All 3 love it and take it like a treat. Never a problem and always tested negative. :) 05/09/2014
    Easy as pie Mishka will be 10 this summer and Heartguard is the easiest to work with. He eats it like a treat!! Never, ever had a problem with it..... 03/14/2014
    A great product for a great pet. Macie just loves her treat she gets every month. She always knows when I take one out of the box. The chewables are so much better than the tablets our Vet gave her when they stopped carring the Heartgard chewables. 01/03/2014
    Willow is a Brindle Chihuahua who loves to eat and demands her mini milk bone snack/reward. Her demands are met in order to stop her loud "talking". After she got her Heart Guard, which she thought was a great "snack" she was waiting for something else! After I left the room she got on my recliner and picked up the Large Milk Bone off the table which was sent in the mail with her Heart Guard! That was a Kodak moment but I didn't have my camera! Little mouth vs Large milk bone! 10/15/2013

    Answer: 
    The medication is Ivermectin. I give Ivermectin medication to my horse and sheep as well as my dogs. Ivermectin does work on most types of parasites but, read the label to be sure.

    Heartworm medicine

    I was told by a vet that even though they recommend heartworm meds every month that 1dose is actually good/active for 3months. Is this information something most vets would agree with?

    Answer: 
    This medication acts by killing any worms or larvae that are present in the blood stream when it is administered. It takes about 6 weeks for the eggs to mature so that is why it is recommended to give a dose every month before the eggs have matured into adult worms.
