Addiction is a chronic brain disease that induces compulsive activity, despite health, social and legal consequences. A person may seem to make a voluntary choice to try a drug or begin a type of behavior, but a variety of genetic and environmental factors influence those decisions.

I certainly won't be able to tell you why your dog died, but frothing at the mouth is something we often see when a dog is dying, no matter what the reason. Sudden death is common when there is an underlying heart problem, sometimes the heart just stops or has an arrythmia that cannot correct itself.
