As summer arrives, the risk of parasitic infections increases for dogs and their human companions. In addition to fleas and ticks, heartworm disease, transmitted through mosquito bites, is a highly infectious threat that affects about one in five dogs on average. Early prevention of heartworm is crucial to avoid potentially fatal consequences.

What is Heartworm Disease?
Heartworm is a common internal parasite in dogs, transmitted through mosquito bites. When a mosquito carrying heartworm larvae bites a healthy dog, the larvae infect the dog’s bloodstream. Over the next 3 to 6 months, the larvae mature into adult heartworms and migrate to the dog’s heart and lungs, leading to noticeable symptoms.

Symptoms of Heartworm Disease:
The symptoms vary based on the size and quantity of the parasites. In the early stages, dogs may show no significant signs except for a slight cough. As the infection progresses, dogs may experience reduced energy, persistent coughing after exercise, and, in severe cases, coughing up blood.

Preventing Heartworm Infections:
Preventing heartworm disease is crucial due to its potential fatality. Here are some effective preventive measures:

  1. Annual Vaccination: Administer the annual heartworm vaccine once a year for continuous protection against heartworm infections.
  2. Regular Use of Heartworm Preventatives: Use products like Canine Heartguard, a monthly internal deworming medicine that not only prevents heartworms but also targets other parasites like roundworms and hookworms. It is safe for dogs aged 6 weeks and above.
  3. Avoiding Mosquito-Prone Areas: Limit your dog’s exposure to mosquito-prone environments, particularly during the summer when mosquito activity is high.
  4. Annual Check-ups and Testing: Regular veterinary check-ups, including blood tests and ultrasound examinations, are crucial for early detection. Annual testing for heartworm antigen can help identify infections in the early stages.

Understanding the severity of heartworm infections emphasizes the importance of proactive prevention. Heartworms pose a life-threatening risk to dogs, and even the surgical removal of heartworms carries significant risks. Preventing heartworm disease through monthly deworming is paramount for the well-being of our canine companions.
