Valuheart Heartworm Tablets offer simple monthly protection against the deadly heartworm (Dirofilia immitis) parasites in your four-legged family member. Heartworm disease is fatal, as the heartworm parasites can infect and clog the dog’s heart, pulmonary arteries, and blood vessels. The disease can impair the operation of the heart and reduce blood flow to other important organs, such as the lungs, liver, and kidneys. Valuheart heartworm prevention eliminates these deadly worms during the developmental stage in the muscle and fatty tissue before they can infect your dog, ensuring your dog’s safety.
