Our Top 10 tips for preventing heartworm
Consult your vet – Schedule a veterinary appointment to assess your dog’s risk, age, weight, and overall health. Your vet can recommend the most effective heartworm preventative and create a schedule for administration and testing.
Administer preventatives consistently – Give oral or topical medications exactly as prescribed, without skipping doses. Missing even one dose can leave your dog vulnerable, so keep a calendar to maintain a schedule.
Year-round Protection – Even in cooler months, heartworm can be transmitted in some regions. Administer preventatives year-round or follow local vet advice to ensure continuous protection against mosquitoes.
Monitor for mosquito exposure – Limit your dog’s time outdoors during peak mosquito activity (dusk to dawn), and use safe barriers like screens, netting, or indoor confinement when possible. Remove standing water near you.
Regular Testing – Schedule annual heartworm tests through your veterinarian to detect infection early. Early detection allows for timely treatment and reduces the risk of severe heart and lung complications.
Check Product Effectiveness – Ensure preventatives are approved by your vet and appropriate for your dog’s breed, weight, and age. Monitor for any side effects and report concerns immediately to maintain safety and efficacy.
Maintain Hygiene and Environmental Control – Keep your dog’s outdoor areas clean, remove stagnant water, and limit access to mosquito-heavy zones. Yard maintenance, combined with preventive medication, significantly lowers the risk of exposure.
Combine Multiple Prevention Methods – Consider safe mosquito repellents or protective clothing for dogs in high-risk areas, under veterinary supervision. Combining environmental and chemical prevention measures increases protection without putting your dog at risk.
Recognise Early Symptoms – Learn to identify signs of heartworm, including coughing, fatigue, weight loss, laboured breathing, or reduced appetite. Contact your vet immediately if you observe any symptoms, even if your dog is on preventive medication, as early intervention can save lives.
Document and Track Prevention – Maintain clear records of all medication doses, vet visits, testing dates, and any symptoms observed. Accurate tracking ensures your dog receives consistent protection, simplifies vet consultations, and helps prevent missed doses that could compromise safety.
