Q. I believe my friends dog has what looks like Class III Heartworm, will her dog eventually die from exhaustion due to severe coughing, dry heaves?

A. This dog must be examined as soon as possible in order to correctly diagnose what is causing his symptoms and to treat as appropriate. Not all coughing is due to heartworm and some causes are more treatable than others. I could not recommend any dog be watched to die slowly from exhaustion, if your friend is not able to afford treatment contact your local humane society and surrender him if necessary in order for him to receive the treatments he requires
