Top 7 Dog Heartworm Treatments The Best Way to Prevent Parasites from Making Your Dog Their Home

Top 7 Dog Heartworm Treatments

Heartworm in dogs is no joke. This vile parasite wheedles its way into your furry pal's heart or lungs and makes them very ill. While there are heartworm treatments, it can be very expensive and stressful, for both you and your dog. Explore the much simpler path of preventative medication and keep your canine heartworm free.

The heartworm is an insidious little parasite that hitches their eggs for a ride on mosquitoes, using these pests as their own personal incubator. They are then transferred from dog to dog via bug bite. Once inside, they make a cozy home for themselves out of your dogs lungs or heart, growing up to a foot long!

While treatment is an option, it can often be time-consuming, stress-inducing, and wallet-depleting. Your best option in keeping your dog safe from the diabolical clutches of heartworm is to give your pooch a monthly preventative. Here are a few good options of heartworm medication for dogs.
