dog. (failure) A failure or a member of a set that, in relation to the norm, is of poor quality.
In this case persons are never dogs, but rather products. Films, plays, and books seem especially susceptible to being dogs. Of course, when Billy Norris of the St. Petersburg Times headlined his review, “Catwoman turns out to be a dog,” the term provided a nice double or even triple entendre, not that anyone has ever suggested that former beauty queen Halle Berry is a dog.
