What is Heartworm Disease

What Is Heartworm Disease?

Heartworm disease is a serious and potentially fatal condition caused by parasitic worms living in the arteries of the lungs and occasionally in the right side of the heart of dogs, cats and other species of mammals, including wolves, foxes, ferrets, sea lions and (in rare instances) humans. Heartworms are classified as nematodes (roundworms) and are filarids, one of many species of roundworms. Dogs and cats of any age or breed are susceptible to infection.

Where is Heartworm Disease?

Naturally acquired heartworm infection in cats and dogs is identified as a worldwide clinical problem. Despite improved diagnostic methods, effective preventives and increasing awareness among veterinary professionals and pet owners, cases of heartworm infection continue to appear in pets around the world.

How Heartworm Happens

Adult female heartworms release their young, called microfilariae, into an animal's bloodstream. Then, mosquitoes become infected with microfilariae while taking blood meal from the infected animal. During the next 10 to 14 days, the microfilariae mature to the infective larval stage within the mosquito. After that, the mosquito bites another dog, cat or other susceptible animal, and the infective larvae enter through the bite wound. It then takes a little over 6 months for the infective larvae to mature into adult worms. In dogs, the worms may live for up to 7 years. Microfilariae cannot mature into adult heartworms without first passing through a mosquito.

What Are the Signs of Heartworm Disease?

For both dogs and cats, clinical signs of heartworm disease may not be recognized in the early stages, as the number of heartworms in an animal tends to accumulate gradually over a period of months and sometimes years and after repeated mosquito bites.

Recently infected dogs may exhibit no signs of the disease, while heavily infected dogs may eventually show clinical signs, including a mild, persistent cough, reluctance to move or exercise, fatigue after only moderate exercise, reduced appetite and weight loss.

Cats may exhibit clinical signs that are very non-specific, mimicking many other feline diseases. Chronic clinical signs include vomiting, gagging, difficulty or rapid breathing, lethargy and weight loss. Signs associated with the first stage of heartworm disease, when the heartworms enter a blood vessel and are carried to the pulmonary arteries, are often mistaken for feline asthma or allergic bronchitis, when in fact they are actually due to a syndrome newly defined as Heartworm Associated Respiratory Disease (HARD).

How Do You Detect Heartworm Disease?

Heartworm infection in apparently healthy animals is usually detected with blood tests for a heartworm substance called an "antigen" or microfilariae, although neither test is consistently positive until about seven months after infection has occurred.

Heartworm infection may also occasionally be detected through ultrasound and/or x-ray images of the heart and lungs, although these tests are usually used in animals already known to be infected.


Because heartworm disease is preventable, pet owners should take steps to talk to their veterinarian about how to best protect their pets from this dangerous disease. Heartworm prevention is safe, easy and inexpensive. While treatment for heartworm disease in dogs is possible, it is a complicated and expensive process, taking weeks for infected animals to recover. There is no effective treatment for heartworm disease in cats, so it is imperative that disease prevention measures be taken for cats.

There are a variety of options for preventing heartworm infection in both dogs and cats, including daily and monthly tablets and chewables, monthly topicals and a six-month injectable product available only for dogs. All of these methods are extremely effective, and when administered properly on a timely schedule, heartworm infection can be completely prevented. These medications interrupt heartworm development before adult worms reach the lungs and cause disease.


Usually, all but the most advanced cases of heartworm disease can be successfully treated in dogs. Cats have proven to be more resistant hosts to heartworm than dogs, and often appear to be able to rid themselves of infection spontaneously. Unfortunately, many cats tend to react severely to the dead worms as they are being cleared by the body, and this can result in a shock reaction, a life-threatening situation. Veterinarians will often attempt to treat an infected cat with supportive therapy measures to minimize this reaction; however it is always best to prevent the disease.

Adult heartworms in dogs are killed using a drug called an adulticide that is injected into the muscle through a series of treatments. Treatment may be administered on an outpatient basis, but hospitalization is usually recommended. When the dog is sent home, exercise should be limited to leash walking for the duration of the recovery period, which can last from one to two months. This decreases the risk of partial or complete blockage of blood flow through the lungs by dead worms.

Re-infection during treatment is prevented by administration of a heartworm preventive. These preventives may also eliminate microfilariae if they are present. Dogs in heart failure and those with caval syndrome require special attention.

The American Heartworm Society





Allflex Microchips are sold in batches of 25 Microchips with 1 Microchip implanter.


Each batch of 25 Allflex microchips is coded so that the batch of 25 microchips can be traced to the microchip implanter/vet. This provides additional security in the event that the microchip number is not recorded properly on a microchip registry.


Microchip Registries


There are five national microchip registries:-


Australasian Animal Registry (AAR)

Central Animal Records (CAR)

National Pet Registry (NPR)

Pet Safe

Homesafe ID


After microchipping; the implanter (your vet, council, welfare organisation or accrediitted implanter) can register the microchip number and animal's details on the above mentioned private microchip registries.


Microchip Registration in NSW


Dogs and Cats microchipped in NSW must be registered on the

NSW Companion Animal Register.

The Companion Animal Register is for microchipped dogs and cats in NSW only.


The Allflex Microchip has a sharp needle with easy use implanter. Each microchip has 5 barcode stickers. Every Allflex Microchip has a 15 digit number adherring to the ISO (International Standards Organisation) standard.


Microchip Scanners


GVP Pty Ltd can supply the following microchip scanners

Trovan LID 560 Microchip Scanner

Allflex ISO (FDX-B) Microchip Scanner

AVID Microchip Scanner

Destron EX Microchip Scanner

and more 


Microchip Frequencies

The Australian Standard requires Small Animal Microchip Implanters to implant the  ISO microchip. These microchips have a 15 digit number. Microchips ISO (FDX-B) are scanned at a frequency of 134.2kHz.

Microchips implanted prior to the ISO standard were scanned at different frequencies;

Microrchips FDX-A Avid, Reunite, Destron , Identichip,(Alphanumeric 125 kHz)

Microchips FDX-A Trovan (Alphanumeric 128kHz)

Early Destron 


Some Microchip scanners read

ISO only Microchips (134.2 KHz FDX-B),

ISO (134.2kHz FDX-B) and FDX-A (125kHz) microchips or

ISO (134.2kHz FDX-B) and FDX-A (125 and 128kHz) microchips

Some scanners will read ISO HDX which is the frequency used in the cattle and sheep eartags adopted by the NLS Australia.

Some scanners will read proprietry encrypted microchips.

All Wormers

Drontal® and Fenpral®

All Wormers such as Drontal® and Fenpral® are recommended for the control of all gastrointestinal worms in dogs.

These all wormers are formulated from three distinctly different proven drugs offering the broadest spectrum of activity. In Drontal the febantel/pyrantel combination is active against roundworms and hookworms and is highly effective against whipworms. Praziquantel provides a superb level of efficiency against all the major tapeworms (including hydatid tapeworm). Fenpral uses Fenbendazole (a metabolite of Febantel) with pyrantel and Praziquantel
