(WGN/CNN) - For thousands of people now living in shelters, the destruction from Harvey has been steady and exhausting.
And while people try to clean-up and rebuild, the most lasting damage may be emotional.
One charity group who started a comfort dog program after Hurricane Katrina is now headed to Houston.
Some of the pets will be sent to a shelter for Harvey survivors. Others will hang out with emergency responders.
"Dogs are good listeners. They're confidential and they show unconditional love. And when people pet a dog they feel safe, particularly if it's a dog that's calm like ours and they talk to the dog," said Tim Hetzner, LCC President.
Organizers say the emotional support a comfort dog provides can be a significant part of the healing process.
