From ANIMAL PEOPLE, July/August 2007:

BANGALORE–A door-to-door canvas of 3.2 million Bangalore
households in mid-June 2007 found just 49,283 dogs– including 17,480
pet dogs, and only 24,491 street dogs, fewer than half the 56,500
estimated to be at large a year earlier.
The plummeting street dog population attested to both the
efficacy of the much-maligned Animal Birth Control programs in
Bangalore, and the undiscriminating tactics of dogcatchers who were
deployed repeatedly in the first half of 2007 to purge dogs.
ANIMAL PEOPLE surveys of dogs in representative Bangalore
neighborhoods found in January 2007 that the ABC programs managed by
Compassion Unlimited Plus Action, Karuna, and the Animal Rights
Fund appeared to have sterilized between 70% and 90% of the
free-roaming dog population. But dog pogroms following fatal dog
attacks in January and March 2007 jeopardized the programs’ success
by killing dogs who had already been sterilized.

From ANIMAL PEOPLE, November 2006:
BEIJING, SHANGHAI–“The year of the dog has been difficult
for man’s best friend,” South China Morning Post reporter Jane Cai
observed on October 26, 2006. “Tens of thousands of canines have

clubbed to death soon by local governments fearing rabies.”
True enough, but the 2006 Year of the Dog appears also to
have been the year that purging dogs began to give way to
vaccination. All year, the Beijing-run state newspapers and news
web sites have been exposing and denouncing dog massacres, always in
the past either praised or ignored.
An October forum on humane rabies control, held in Shanghai,
drew high-profile national coverage.
