Miracle Dog: How Quentin Survived the Gas Chamber to Speak for Animals on Death Row is a non-fiction book written by Randy Grim.
 Published in February 2005 by Blue Ribbon Books, the book details the story of a dog named Quentin, who survived fifteen minutes in a carbon monoxide gas chamber at the St. Louis, Missouri animal shelter in 2003.
 Grim, the president and founder of Stray Rescue of St. Louis, adopted the dog and used his story to campaign against the use of the gas chamber for Animal euthanasia and to support no-kill animal shelters.
 As a result of Grim's efforts, the St. Louis animal shelter stopped using the gas chamber in January 2005, switching to more humane euthanasia methods.

An animal shelter or pound is a place where stray, lost, abandoned or surrendered animals, mostly dogs and cats, and sometimes sick or wounded wildlife are kept and rehabilitated.
 While no-kill shelters exist, it is sometimes policy to euthanize sick animals, and any animal that is not claimed quickly enough by a previous or new owner.
 In Europe, of 30 countries included in a survey, all but four (Czech republic, Germany, Greece, and Italy) permitted the killing of healthy stray dogs.
 Critics believe the new term "animal shelter" is generally a euphemism for the older term "pound".
 The word "pound" had its origins in the animal pounds of agricultural communities, where stray livestock would be penned or impounded until claimed by their owners.
 Some shelters even have sick tropical animals.

A "no-kill" shelter is an animal shelter that does not kill healthy or treatable animals even when the shelter is full, reserving euthanasia for terminally ill animals or those considered dangerous to public safety.
 A no-kill shelter uses many strategies to promote shelter animals; to expanding its resources using volunteers, excellent housing and medical protocols; and to work actively to lower the number of homeless animals entering the shelter system.
