I know that this is not a darts related topic but i felt compelled to mention this site.  Heartworm Prevention & Medication.

Heartworm is one of the major killers of dogs and can be so easily prevented by simply giving your dog a pill, or using one of the “spot on” products that are available.

If you own a dog, please ensure that it is on heartworm medication and if it isnt, seriously consider buying some heartworm medication immediately.

A look at the graphic video footage will indicate what can happen when this condition remains untreated.
