Heartworm Awareness Month: Protect Your Dog from This Silent Threat

Heartworm Awareness Month is an important reminder for all pet owners to take action against a potentially deadly but preventable disease. Heartworm disease is caused by parasitic worms that live in the heart and blood vessels of infected dogs, leading to serious health complications if left untreated. 

As veterinarians, we often see how devastating heartworm disease can be, but the good news is that with proper prevention and early detection, your dog can stay safe and healthy. 

Common Signs of Heartworm Disease in Dogs 

Heartworm disease can be difficult to detect in its early stages, as many dogs show few or no symptoms at first. As the disease progresses, you may notice: 

• Coughing or laboured breathing
  • Fatigue after mild exercise
  • Weight loss or loss of appetite 
  • Lethargy or weakness 
  • Swollen abdomen due to fluid buildup 
  • Collapse in severe cases 

If you notice any of these signs, it is important to contact our veterinary team promptly for assessment and testing. 

How Dogs Get Heartworm 

Heartworm is spread through mosquito bites. When a mosquito bites an infected dog, it picks up microscopic heartworm larvae. These larvae are then transmitted to another dog through the next bite. 

Factors that increase risk include: 

• Warm and humid weather where mosquitoes thrive
  • Outdoor exposure, especially at dawn and dusk
  • Lack of regular parasite prevention 
  • Living near standing water or bushland areas 

Because mosquitoes are present in many regions, heartworm prevention is essential for all dogs, even those that spend most of their time indoors. 

Tips to Protect Your Dog from Heartworm 

• Year-round prevention:Monthly chewable tablets or annual injections are the most effective way to protect your dog from heartworm disease. Your vet can recommend the best option for your pet’s lifestyle. 

• Regular testing: Annual heartworm blood tests help detect infection early before serious damage occurs. 

• Mosquito control: Reduce standing water around your home and use pet-safe repellents when appropriate. 

• Stick to a routine: Set reminders to ensure your dog never misses a dose of prevention medication. 

• Combine parasite protection: Many heartworm preventatives also protect against intestinal worms and other parasites, making prevention simple and effective. 

When to See a Vet 

If your dog is not currently on heartworm prevention, or if you have missed doses, it is important to book a consultation. Testing is required before starting prevention to ensure your dog is not already infected. 

Early detection and prevention are far safer and more affordable than treating advanced heartworm disease. 

During Heartworm Awareness Month, take the time to check your pet’s parasite prevention plan and speak with your vet about the best protection strategy for your dog.
