Heartgard medicine for pet



Pet Size

Don't know your pet's weight?

If you can't get them on the scale, try this super simple method:

  1. Weigh yourself.
  2. Weigh yourself holding your pet.
  3. Subtract the two numbers to get their weight.

Too heavy to hold? Your vet will weigh them if you ask (or may already have it on file if you call).


  • Description

    Heartgard is heartworm prevention medication for dogs and cats. It defends a pet’s cardiac health from being endangered by these parasitic worms that animals can be exposed to when they are bitten by mosquitoes - something that is difficult to prevent if your pet is outdoors often. Heartgard is used to prevent canine heartworm disease that occurs when these worms are allowed to multiply, and if left unchecked this disease can be fatal for the animal. Fortunately, Heartgard for dogs or Heartgard for cats provides year-round protection against heartworm disease when taken on an ongoing basis.

    Buy Heartgard chewables from World Pet Express and get the best price on this effective heartworm medication.


    Heartgard chewable are flavored so that your dog or cat will happily eat them and begin enjoying the heart protection benefits of this medication. Administering them to your pet is easy. You can very likely feed them to him or her by hand but if not, you can then mix the tablet into wet dog food or cat food and have them ingest the anti-heartworm medication that way.

    Just one chew per month 12 times a year and you can count on your pet having protection against heartworm disease.


    The active ingredients in Heartgard are Ivermectin and Pyrantel Pamoate.


    Heartgard is a safe heartworm killer medication for dogs and cats, but some precautions should be followed with the use of it. First, all dogs should be tested for heartworm infection before starting a preventive program.

    Next, be sure to never give your pet more than one chewable in a month, no matter if you have concerns about the effectiveness of it or not. Heartgard contains melosomine dihydrochloride, a compound that can be toxic in elevated amounts, so you must not give your pet more than one chewable a month.

    In addition, Heartgard should not be taken concurrently with any other heartworm medication for dogs.


    Heartgard is FDA and EPA approved, and is not to have any interaction risks with any other medication or supplement products.
