Heartworm is a serious medical condition that affects dogs and cats, especially in the United States. The disease is caused when parasitic worms, measuring up to a foot long, enter the host’s heart, blood vessels, and lungs. The infection leads to various medical complications such as lung disease and even heart failure. Heartworms complete an entire life cycle within the host’s body. What that means is they grow, mate and breed inside your dog’s body and if left untreated, their numbers can go from hundreds to thousands. But, even with treatment, heartworms cause enough long term damage to your dog’s body. As a result, your dog may never fully recover. This is where the prevention approach is the best approach.So, how do you prevent heartworm infection? Well, there are primarily three categories of heartworm medication that prevent infection.
