One Mosquito

is all it takes to transmit
heartworms to your dog.

Heartworm larvae are transmitted by infected mosquitoes. When the infected mosquito bites, the larvae pass through the tissue into the bloodstream. 70 days later they reach the arteries of the lungs where they continue to develop and grow.

Once they arrive in the lungs, at 70 days post-infection, they can start to do damage.

 
 

What Exactly Is

Heartworm Disease?

  • Heartworm disease is a serious and potentially fatal condition in dogs

  • It is caused by worms that spend their adult lives on the right side of the heart and the large blood vessels that connect the heart to the lungs

  • It is transmitted through infected mosquito bites

  • Dogs of all ages are susceptible to infection

  • Signs range from no sign at all to persistent cough, fatigue, fainting and weight loss

  • Heartworm disease is usually detected with a blood test

  • Treatment is an expense for the owner, and a painful, prolonged ordeal for the dog

  • Prevention of heartworm disease is recommended versus heartworm disease treatment

Left Untreated, the Heartworm Larvae Can

Continue to Grow and Grow

After entering into the tissue, the heartworm life cycle begins with the presence of infected larvae. Once larvae arrive in the heart and lungs, they can cause damage as early as 70 days.

 
 

Adult worms can extend up to
12 inches long—creating serious damage.

Yikes!
