    What is Heartworm?

    Do you know how to protect your dog from heartworm?

    Do you know the signs?

     The American Heartworm Society reports that more than one million dogs currently have heartworm disease. They also report that heartworm is a serious canine and feline health concern that threatens animals in all 48 contiguous states and Hawaii, as well as throughout the temperate regions of the world. April is Heartworm Awareness Month.

    Dogs get heartworms only by being bite by an infected mosquito and live in the heart and pulmonary arteries of infected animals. The disease can lead to heart failure, as well as damage to other organs. 

    Some myths state that it is spead from animal to animal by mosquitoes.  According to the American Heartworm Society this is not true.

    Dogs are a natural host for heartworms. Heartworms that live inside the dog mature into adults, mate and produce offspring. If untreated, their numbers can increase, and dogs have been known to harbor several hundred worms in their bodies. Heartworm disease causes lasting damage to the heart, lungs and arteries, and can affect the dog’s health and quality of life long after the parasites are gone. That's why, heartworm prevention for dogs is so important.
