One mosquito bite can change your dog's life. It might even take it.

So — read this before it's too late.

What is heartworm?

Heartworm (Dirofilaria immitis) is a parasite that lives in a dog's heart and lungs.

It's transmitted through a mosquito bite, and it takes up to 6 months to develop from larva to adult worm – with no symptoms.

How does a dog get infected with heartworm?

  1. A mosquito transmits the larva when it bites
  2. The larva travels through the body
  3. It settles in the heart and lungs
  4. It grows into a worm up to 30 cm long
  5. Your dog becomes seriously at risk, and you're not even aware of it

Symptoms of heartworm in your pet (but they come late)

⚠️ Unfortunately, symptoms often appear once things are already serious:

  • Coughing, tiring quickly
  • Weight loss
  • Refusing food
  • Dark urine
  • Pale gums
  • In severe cases: sudden death

Why is heartworm dangerous?

A single dog can have dozens of worms in its heart and lungs.

They cause:

  • Damage to the heart and blood vessels
  • Pulmonary embolisms
  • Damage to the liver and kidneys
  • A high risk during treatment

How does a DOG DEFEND itself against heartworm?

❌ It can't, on its own.

✅ Prevention is the only safe way!

Prevention: What you can do to protect your pet from heartworm?
