As a caregiver, it’s crucial that you understand the risks and preventative measures associated with heartworm disease in dogs. Let’s dive into the details.
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. These worms are transmitted through the bite of an infected mosquito.
How are Dogs Infected with Heartworms?
-
The Cycle Begins with Infected Dogs: Dogs already infected with heartworms serve as the primary source of the disease. The heartworms in these dogs produce offspring, which circulate in the bloodstream.
-
Mosquitoes are the Carriers: When a mosquito bites an infected dog, it sucks up these baby worms. Over 10-14 days, these worms mature within the mosquito into a more dangerous form.
-
Transmission to Healthy Dogs: When the mosquito bites another, uninfected dog, these matured worms are deposited onto the skin and enter the new host through the mosquito bite wound.
Symptoms of Heartworm Disease in Dogs
Initially, a dog with heartworm may show no symptoms. However, as the disease progresses, you may observe:
- Mild persistent cough
- Lethargy after moderate exercise
- Decreased appetite and weight loss
- Swollen abdomen due to excess fluid
Prevention of Heartworm Disease
Preventing heartworm disease is far easier, safer, and cheaper than treating an infected dog. Here are some preventative measures:
-
Year-Round Heartworm Prevention: Several products can prevent heartworm infection in dogs. Consult with your vet to choose the best one for your pet.
-
Regular Tests: Annual testing for heartworm is recommended, even if your dog is on prevention. This ensures that the prevention program is working.
-
Mosquito Control: Reducing your dog’s exposure to mosquitoes can help reduce the risk of heartworm infection.
