Is There an Effective Heartworm Preventative?

Heartworm is a serious disease for dogs and cats. When infected by mosquitoes carrying heartworm larvae, animals can become infected in less than two weeks. Heartworm prevention comes in the form of three medications.  Veterinarians and researchers worked since the late 1900s to develop these heartworm preventative medications.

The three main heartworm preventatives are:

  • Ivermectin,
  • Milbemycin,
  • and Moxidectin.

All three medications have been tested and approved by the FDA, and are arsenic-based compounds that are capable of killing the heartworms in their larval forms before they can hatch. Furthermore, Ivermectin, Milbemycin, and Moxidectin are available as a chewable tablet. Unlike the first two though, Moxidectin is also available as a “sustained-release” injection that can be used for 6 to 12 months depending upon the shot a dog receives.

Heartworm Preventative Statistics:

  • Heartworm preventatives are safe for puppies under 7 months of age.
  • A dog cannot infect another dog with heartworms.
  • Heartworm treatments are almost always effective.
  • Heartworm preventatives have a proven track record of success.
  • To develop heartworms, three prerequisites exist. Those are the presence of a mosquito with the parasite, a dog with the parasite, and the right temperature. If one or more of these is missing, then heartworm parasite will not take hold in your dog.

A good heartworm preventative strategy is a must for any dog owner.  Especially those who live near or within mosquito prone regions. The proven and responsible way to protect your pet from heartworms is prevention. The risk to dogs is too great to not take the time and effort to prevent such a disease as heartworm.
