Preventive medications for heartworm in Border Collies include options such as ivermectin, milbemycin oxime, and selamectin. These medications are typically administered monthly and are effective in preventing heartworm disease caused by the parasite Dirofilaria immitis. It's essential to consult a veterinarian for the best preventive option tailored to your Border Collie's health and lifestyle. Regular testing is also recommended to ensure they remain heartworm-free.
