Have a Heart – Protect your Pet from Heartworms

That simple preventative that your veterinarian keeps recommending costs 15 times less than treatment!

It’s easy to shrug off your veterinarian when you’re asked if your pets are up to date with heartworm prevention. What are the odds of your pet contracting heartworm anyway right? Well – the answer is, you don’t want to find out!

Take these facts to heart before you dismiss another opportunity to protect your pet from heartworms.

Heartworms are a real danger.

Heartworms pose a serious threat to both your dogs and cats health. In pets, adult heartworms can grow up to 30cm in length, blocking the arteries leading to the lungs and infesting the heart. As a result, the heart is forced to pump extra hard to keep blood flowing, which can lead to heart failure. The disease can also severely damage other parts of the body, such as the liver and kidneys. It affects many types of animals, including domestic and feral dogs and cats, dingoes and foxes.

Heartworms are transmitted by mosquitos – just one bite could infect your pet.

Mosquitos can survive and thrive in a variety of climates and environments. They can drink three-times their weight in blood and spread heartworm larvae as they feed.

Pet owners do not usually see any symptoms of heartworm disease until the infection has advanced.

Symptoms of heartworm in dogs include:

  • A dry, chronic cough
  • Fainting
  • Weight loss
  • Breathing difficulties
  • Difficulty with exercise
  • Ascites (where the abdomen swells up due to the fluid build-up because the heart cannot pump normally)

Symptoms of heartworm in cats include:

  • Coughing
  • Gagging
  • Raspy breathing
  • Vomiting

Heartworm is often misdiagnosed as asthma.


Mosquito season is impossible to predict.

Year-round protection is essential to ensure protection. It only takes one bite from a mosquito to infect an animal. Mosquitos are more prevalent in warm climates, but heartworm is diagnosed across the country. If a mosquito bites an infected animal, then bites your pet, your pet is at risk of infection. As each new animal is infected, the risk of heartworm grows.


Heartworm disease is hard to treat.


A heartworm infestation is difficult and expensive to treat in dogs and there is no approved treatment for cats. Treatment for heartworm disease is expensive and difficult, often requiring hospitalisation, and may require harsh drugs to kill the adult heartworms. Some dogs do not survive this treatment.


It takes approx­imately six months for a dog to test positive for heart­worms and they can grow more than 12 inches in length living in a dog’s heart, lungs or blood vessels for up to seven years.


Just one adult heartworm can kill a cat and there is no safe way to treat heartworm in cats.


Heartworms are easy to prevent.

Heartworm preventives are effective and easy to administer to pets. Plus prevention is much cheaper than treatment. Treat­ment costs more than 15 times that of a year’s worth of heartworm preventive.

For dogs, there is a yearly injection which can be given at the same time as their yearly vaccination. There are also monthly chewables/tablets available. If there’s a chance that you may forget a monthly dose of heartworm prevention, we would definitely recommend the yearly injection.

For cats, there is only a monthly top spot formulation available.
