Sober Eye Dog
A dog trained to guide his master when the master becomes extremely intoxicated on alcohol or other drugs. The dog aids the master in continuing to function as if he were still a sober human being. Similar to a seeing eye dog but the people for whom the sober eye dog assists are fucked up drug heads and not actually blind.

George: Fuck that he has his sober eye dog to show him the way.
