Rescue groups go deep into the shelter to look for dogs to save. The back rooms at the shelter are sometimes loud with barking, and sometimes eerily quiet. There are all kinds of dogs at the shelter–pure bred and mutt, small and large, old and young, stray and owner-surrendered. Strays are held for a minimum of 3-5 days in case someone comes looking for them. Because no one is going to come for owner surrenders, they may be euthanized immediately if space is needed. 2013.
