Heartworm prevention is a MUST if you have misquitos in your area. Heartworms can kill your dog! It's definatly not something to mess with. Yes, HW prevention may seem highly priced, but it's nothin compared to the treatment once your dog has them. You can buy HW prevention at your vet's office. It's the most reliable place to buy it.
