Florida is still reeling from the biggest mass shooting in recent US history.
Forty-nine people were killed and 53 injured at the Pulse gay nightclub in Orlando on Saturday night.
But a specialist team has been dispatched to Orlando to provide relief.
A group of comfort dogs went to the city on Tuesday to help out anyone affected by the shooting and were accompanied by a team of volunteers.
The dogs are provided by Lutheran Church Charities. They say they are working with hospitals to help the injured as well as first responders from Orlando's emergency services.
Tim Hetzner is president of the LCC Comfort Dogs.
"They help people relax and calm down," he told ABC News, external.
"Your blood pressure goes down when you pet a dog, you feel more comfortable and people end up talking.
"They're good listeners, they're non-judgmental and they're confidential."
Unlike guide dogs, these dogs wear jackets saying "please pet me"
Comfort dogs have helped out after other other shootings and terror attacks.
They were in Boston after the marathon bombing in 2013 and at Sandy Hook after 20 children and six adults were killed in a shooting in 2012.
The service is free for people who use it and is funded entirely by donations.
Comfort dogs receive special training to provide emotional support in places like nursing homes, hospitals and disaster situations.
According to the American Kennel Club there are more than 120 organisations, external that provide comfort dogs.
The Lutheran Church Charities' K-9 Comfort Dogs is one of those organisations.
As well as volunteers they have trained dog handlers and have been going since 2008.
