Heartworm disease (caused by Dirofilaria immitis) is a serious and potentially fatal condition that has been diagnosed in dogs in all 50 states of the U.S. and around the globe. As heartworms are spread by mosquitoes, protection is necessary wherever mosquitoes exist. The American Heartworm Society (AHS) strongly recommends year-round prevention for all dogs.<\/p>\n <\/div>\n\n

3 Critical Reasons for Year-Round Prevention<\/h2>\n\n

1. The Risk Never Reaches Zero<\/h3>\n\n

Heartworm transmission decreases in colder months, but the presence of microclimates\u2014especially in urban areas\u2014means the risk of transmission never reaches zero. Factors like “urban heat islands” (buildings and parking lots retaining heat) create microenvironments that can lengthen the transmission season.<\/p>\n\n

2. Preventives Work Retroactively<\/h3>\n\n

Heartworm preventives work retroactively, eliminating new infections that were transmitted months earlier. Since the heartworm life cycle is long (usually 7 to 9 months), a monthly dose given today treats any infection acquired over the past month or longer. Stopping prevention during winter risks leaving a newly acquired infection to mature.<\/p>\n\n

3. Consistency is Key<\/h3>\n\n

Heartworm preventives need to be given on time, every time, to be effective. Consistent administration year-round is essential because missing a dose or being late with it could create an infection opportunity. Continuous, year-round administration is a partial safeguard against inadvertent delays or omissions.<\/p>\n\n

The AHS-Recommended Multimodal Approach<\/h2>\n\n

The AHS recommends an approach involving medication and risk reduction:<\/p>\n\n

    \n
  • Year-Round Preventive Medication:<\/strong> Veterinarians should prescribe year-round administration of FDA-approved preventive drugs. These drugs belong to the Macrocyclic Lactone (ML) class and are available only by prescription from a veterinarian.<\/li>\n
  • Annual Testing:<\/strong> Have your veterinarian test your dog each year for heartworm infection. Testing helps ensure early diagnosis and treatment.<\/li>\n
  • Vector Control:<\/strong> Reduce your dog’s exposure to mosquitoes by limiting outdoor activity during peak feeding times (dusk and dawn) and eliminating sources of standing water where mosquitoes can breed. The AHS also notes that applying an EPA- or FDA-approved mosquito repellent\/ectoparasiticide can increase the overall efficacy of a prevention program.<\/li>\n <\/ul>\n\n

    Consult Your Veterinarian<\/h2>\n\n

    Heartworm prevention is a medical decision. Always consult with your pet’s doctor to discuss the best product and strategy for your dog.<\/p>\n\n
