Heroes come in all shapes and sizes -- and these ones are extra furry!

Following Monday's tragic bombing in Boston, the Lutheran Church Charities of Addison, Ill., is sending five golden retrievers to the city to offer comfort to those affected by the explosions. The dogs are specially trained through the church's non-profit effort K-9 Comfort Dogs. 

"People talk to the dogs. They’re like furry counselors," Tim Hetzner, president of Lutheran Church Charities, told Today.com. “It’s a chance to help bring some relief to people that are shaken up because of the bombings.” 

Two of the five dogs headed to Boston are already stationed in Newtown, Conn., where they've been providing comfort to those affected by the horrific school shooting that occurred in the town last December. They'll join three other dogs -- including Luther and Ruthie (pictured above) -- in Boston this week. 

According to K-9 Comfort Dogs' website, each of the dogs has been trained for more than a year to help people in stressful situations.
