Signs of heartworm disease may include a mild persistent cough, reluctance to exercise, fatigue after moderate activity, decreased appetite, and weight loss. As heartworm disease progresses, pets may develop heart failure and the appearance of a swollen belly due to excess fluid in the abdomen.
Common symptoms of heartworms in dogs

How soon after infection will a dog show signs of heartworm? - Haywood Animal Hospital. It can take several months to start seeing actual signs, as it takes anywhere from six to eight months for the larva to reach the adult stage. It can even take up to two years to see any signs.
Heartworm (Dirofilaria immitis) in dogs is considered endemic in Australia, but the clinical heartworm disease caused by the heartworm is rare and prevalence is low. The mainstream prevention of the heartworm is based on macrocyclic lactone (ML) administration.
Heartworm prevalence in Australia
Queensland and New South Wales are considered to be areas of higher risk whereas rates in South Australia are low (4,5).
How Long Can a Dog Live Without Heartworm Treatment? A dog can live at least six to seven months from the date of infection.
A persistent, dry cough is a common sign seen in dogs with advanced heartworm disease. The cough caused by heartworm disease can be one of the first signs you notice in an otherwise healthy-appearing dog.

Physical exertion has been proven to increase complications from heartworm treatment, and there's a direct correlation between the level of activity and the severity of disease. This period of rest and recovery should start at diagnosis and continue until 6 to 8 weeks following your dog's last melarsomine injection.

A class four heartworm infection is also often referred to as caval syndrome in dogs. This stage is characterized by complete organ failure, and sadly most dogs with a stage four heartworm infection will end up passing away.
The adult worms die in a few days and start to decompose. As they break up, they are carried to the lungs where they lodge in the small blood vessels and are eventually reabsorbed by the body.
Dogs with heartworm disease can live high-quality lives as long as they are given appropriate care. After completing treatment and following your veterinarian's recommenda- tions on heartworm disease testing and prevention, the chances of any long-term effects are very low.
All dogs are at risk, even those that are indoors only. Untreated, heartworm disease can result in severe heart damage and even death.
