Heartworm (Dirofilaria immitis) is a serious concern for pets in many countries, including Australia, but it does not exist in New Zealand. Thanks to strict biosecurity and border controls, New Zealand remains heartworm-free, meaning dogs and cats living here do not require heartworm treatments.
Does My Dog or Cat Need Heartworm Treatment?
If your pet lives in New Zealand, heartworm prevention isn’t necessary. However, if you’re planning to move your pet overseas or bring a pet into New Zealand from a country where heartworm is present, treatment is required. We recommend speaking to your vet well in advance, as preparing your pet for travel can take several months.
What Is Heartworm?
Heartworm is a parasitic worm that can be transmitted between animals and by mosquitoes. It can reside in the heart and lungs of affected animals, causing serious health issues, and if left untreated, it can be fatal for pets.
Parasite Control in New Zealand
While heartworm isn’t a concern for pets in New Zealand, dogs and cats can still be affected by other parasites that require regular treatment, such as fleas, ticks, lice, mites, and gastrointestinal worms like tapeworm, hookworm, roundworm, and whipworm. Your vet can advise on the best treatment plan for your pet.
