I have to say, sometimes something worming its way into your heart is not a good thing. Case in point, heart worms, the topic this week. Kent and Cory talk preventatives, symptoms, and other random tangents. The only time you should not have heart worm prevantitives, or have any concerns for your dog regarding heart worms, is if you live somewhere that mosquitoes exclusively do not live and will never be. If that doesn't describe your locale, take care of your doggo's heart.
