Pet adoption agencies are pushing to find homes for a growing number of retired greyhounds.
The surge comes amid a struggling dog racing industry and a weak U.S. economy that has some people saying they can't afford a pet.
Many of the estimated 300 adoption groups around the country are seeing increases in returns of adopted greyhounds and declines in new adoptions.
While some groups say there is no way to determine exactly how many greyhounds are adopted annually, the Abilene, Kan.,-based National Greyhound Association estimates the number at about 20,000.
The group's executive director, Gary Guccione, is predicting a stop this year to the steady increases in Greyhound adoptions.
He says the racing industry has been hurt by stagnant purses and the rising cost of raising a greyhound.
