Heartworm awareness is important for all greyhound owners and trainers

The Queensland Racing Integrity Commission (QRIC) is calling on all greyhound owners and trainers to be aware of the threat of heartworm disease to the racing dog population.

QRIC principal veterinarian Dr Celia Solorzano said left untreated heartworm infestation affects the quality of life and the racing performance of greyhounds.

“It amounts to irresponsible dog ownership not to manage heartworm, as it can easily be prevented but if infested it was difficult to treat,” she said.

Dr Solorzano said the treatment could be dangerous and unpleasant for dogs and even if the worms were eliminated the dogs could be left with permanent damage.

“Therefore, prevention is definitely better than cure,” she said.
Heartworm is a parasitic nematode (Dirofilaria immitis) that is transmitted to dogs by both saltmarsh and freshwater mosquitoes.

An increase in the mosquito population at this time of the year particularly in north Queensland increases the risk of heartworm infestation in dogs.

Heartworm larvae migrate in the blood vessels of dogs to mature in the pulmonary arteries and the heart. Adult heartworms can reach 30cm in length and can live for up to eight years.

Dr Solorzano said symptoms usually begin with a cough, and when the worms mature they crowd in the dog’s heart.

“Circulation and respiration are impacted, and as a result, dogs will tire more quickly and have difficulty exercising and eventually most dogs will die if the worms are not treated,” she said.

“The prevention of heartworm in dogs is very simple and inexpensive, and every greyhound in Queensland should be on a preventative program beginning when they are puppies.

“There are several options for heartworm prevention, including a monthly medication. There is also an annual injectable preventative medication.

“However, dogs must be tested for pre-existing heartworm infestation before prevention can begin.”

Greyhound owners should discuss options for appropriate heartworm preventatives with their veterinarians.
