Of greater significance are the numbers of animals rescued from hoarders who actually purport to be operating no-kill shelters. There was some improvement on that front in 2011, but those cases shouldn't exist at all:
From ANIMAL PEOPLE, November/December 2010: [EXCERPT] The numbers of dogs and cats taken in from failed animal shelters and nonprofit shelterless rescues in 2010 appear likely to exceed the numbers impounded from breeders for the first time in the 19 years that ANIMAL PEOPLE has kept track. About 4,600 dogs and cats had been taken in from failed shelters and rescues as of Thanksgiving 2010, almost the same as the then-record number taken in from failed shelters and rescues in the whole of 2009. The 2010 figure projects to a total of nearly 5,000 for the year, or 25% of the total number of dogs and cats impounded in neglect cases.
From ANIMAL PEOPLE, January/February 2012:
Puppy millers move from malls to web sites [EXCERPT] Impoundments of dogs and cats from failed shelters and rescues rose from 2,159 in 2005 to nearly 5,000 in 2010, exceeding the number impounded from puppy mills for the first time, but dropped back to 3,165 in 2011.
