Is heartworm disease prevention necessary?

Heartworm disease is a potentially deadly disease that can cause permanent damage to dogs’ health even before it can be diagnosed. When an infected mosquito bites a dog, they get exposed to the risk of heartworm disease. If neglected and left untreated, it can lead to heart failure and eventually death of the infected dog. The treatment of heartworm disease is complicated and expensive. Compared to this, heartworm disease prevention is simple. Nuheart is one such convenient treatment to prevent heartworm disease.

Do all dogs need heartworm disease prevention?

Heartworm disease has been reported in all 50 states of the US in both indoor and outdoor pets. Also, a dog of any age can get infected with heartworm disease. Nuheart attacks the tissue larval stages of heartworms within 30 days of infection, preventing their growth.

Incidence-Map
How do dogs get infected with heartworms?
mosquito bite
It all starts with a mosquito bite.
  1. A mosquito bites a heartworm-infected animal and ingests heartworm larvae.
  2. The heartworm larvae develop to the infective larvae stage inside the mosquito.
  3. The mosquito bites a dog.
  4. The heartworm larvae enter the tissue of the new host, and reach adult & mature adult stages in the bloodstream. Treatment is necessary at this stage.
