Greyhounds killed at British sanctuary?

From ANIMAL PEOPLE, November 2006:
MANCHESTER–The Leigh Ani-mal Sanctuary
in Greater Manchester, Britain, on September
17, 2006 began refusing to accept greyhounds,
the same day that Daniel Foggo of the London
Sunday Times recounted that “a reporter posing as
a trainer who wanted two healthy dogs killed” met
“an employee called David [who] accepted £70 in
cash to kill two young greyhounds,” no questions
asked.
“Three greyhound trainers have given
interviews, on condition of anonymity, stating
that the sanctuary has been the killing ground of
choice for the greyhound racing industry in the
northwest for many years,” wrote Foggo.

In July 2006 Foggo disclosed the
activities of a private individual, David Smith
of Seaham, County Durham, who had allegedly
killed as many as 10,000 retired greyhounds over
the years using a captive bolt gun, burying the
remains in a large garden.
Opened in 1975, the Leigh Animal
Sanctuary kills half the dogs it receives,”
Foggo said. A 50% euthanasia rate is not unusual
in the U.S., but is almost unheard of in
Britain, which as a nation kills fewer shelter
animals than some large U.S. municipal animal
control shelters, and where “Ameri-can” pit bull
terriers, making up more than half the U.S.
shelter toll, have been banned since 1991.
The ban exempts “Staffordshire” bull
terriers however, who are essentially the same
dog breed in white rather than brindle
coloration, and are now the dogs most likely to
be surrendered to British shelters; greyhounds
may be a distant second. Dogs Home Battersea,
believed to lead Britain in placing both
ex-racing greyhounds and Staffordshires, in
mid-October 2006 disclosed that Staffordshires
made up 15% of their dog intake in 2005, and 36%
in September 2006. Mongrels by contrast were
28% of admissions in 2005, 16% in September 2006.
