What are heartworms?
Heartworms are parasitic worms that live in the heart and blood vessels of pets. Dogs and cats become infected when bitten by a mosquito carrying heartworm larvae, which are then transmitted to the animal. Certain areas, particularly those with standing water or high mosquito populations, have a greater risk of heartworm infection for pets.

Why prevent heartworms?
Heartworm infection can be fatal if left untreated. Potential complications include:
- Damage to the lining of the arteries
- Blockage of the pulmonary artery
- Heart failure
- Damage to heart valves
Preventing heartworms is far safer and more effective than treating them after infection.

How to you prevent heartworms?
Heartworm prevention is available as a monthly oral tablet or a topical treatment. Year-round protection is essential to keep your pet healthy.
Even indoor cats need heartworm prevention, as a single mosquito bite can transmit the infection. No pet is completely safe from heartworms, regardless of whether they stay indoors.
