Jul 20, 2007 — On Thursday, Brian Mann looked at the plight of tens of thousands of dogs, mostly pit bulls, exploited and killed every year by illegal dog fighting rings. Animal control experts say dog fighting is only one small front in a national pet crisis. Put simply, there are too many dogs and cats in America. Every single day, more than 11,000 unwanted pets are euthanized. Hundreds of thousands more live in horrific conditions. Today, in part two of a special project reported for National Public Radio, Brian Mann reports on the effort to reduce ease the pet overpopulation crisis.
