Heartworm protection for dogs in the United States is essential to prevent serious and potentially fatal infections caused by parasitic worms transmitted through mosquito bites. Heartworm disease primarily affects the heart, lungs, and blood vessels, and can lead to severe complications if left untreated. Preventative medications are available in oral, topical, and injectable forms and are typically administered monthly or annually. Most heartworm protection for dogs requires a veterinary prescription, as treatment must be tailored to the dog’s weight, age, and health status. Regular testing and year-round prevention are recommended, especially in regions where mosquitoes are active throughout the year.
