DENVER -- Colorado's only greyhound-racing facility ended its racing season on Sunday, and now the track's owners say they need to find homes for 200 dogs.

Mile High Racing and Entertainment in Commerce City must get rid of the dogs in 45 days. The dogs must either be transported to other states to continue racing, used for breeding or adopted out of the sport and retired.

The dog owners wanted to race year-round, but the track operator only wanted to race part of the year. Mile High Racing and Entertainment told 7NEWS they tried a full season of racing in 2007 and lost $700,000. Because the two sides could not reach an agreement, the Colorado Racing Commission withdrew the rest of the dates for the racing season.

"Most of our dogs will go to Iowa and West Memphis," said Keith Legg, trainer of Legg Kennels.

But not every kennel can afford to send their dogs out of state to race. Some are having to close down their operations, said Rocky Mountain Greyhound Adoption.

For now, RMGA said the dogs currently at Mile High will be transferred to a facility in Pueblo.

"I don't think there is concern we are going to see massive greyhound deaths," said Jan Woll, with Rocky Mountain Greyhound Adoption. "We are concerned about how long they are going to be there and what the conditions might be."

It's estimated around 200 dogs will need to be adopted out or placed into foster homes.

There are five greyhound rescue organizations in Colorado. All of them are looking for help, financially and for families willing to take in some of these greyhounds.
