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.

The dog may frequently dribble urine or pass smaller amounts of urine than usual and the urine is bloody or cloudy and is foul-smelling, plus, the dog may become suddenly thirsty all the time. Other symptoms include lack of energy and loss of appetite although these are not very common.
