Heartworm disease is a serious, preventable parasitic infection in dogs transmitted by mosquitoes. Prevention is far safer and more humane than treatment.
Heartworm disease causes significant suffering — chronic cough, exercise intolerance, respiratory distress, and heart failure. Dogs with advanced disease endure months of illness and painful treatment protocols involving arsenic-based injections and strict confinement. Prevention is not only more cost-effective but dramatically reduces animal suffering. Owners in endemic areas who delay or skip prevention expose their dogs to avoidable distress.
