The dogs are being called "second responders."

In the wake of the horrible attack that occurred in Las Vegas a little over one week ago, millions of people around the world have done their part to help in any way they can, whether that's donating blood, donating money online, or even traveling to Las Vegas to take part in the services and performances that have been held there. Following such a tragedy, there is one group that arrived in the city to help that victims and their families are particularly glad to see: therapy dogs.

Therapy dogs and even other animals are usually at the ready for those in the hospital for long periods of time, senior citizens, and even college students in the midst of finals week. They provide a comfort that is unspoken and can't often be fulfilled by humans by offering their unconditional affection during some tough times. That's why no one was surprised when over one dozen therapy dogs arrived in Las Vegas within hours after the attack, but the relief they brought to those they visited was palpable.

A group of 17 comfort dogs was brought in during the early morning hours following the attack and they were all from Lutheran Church Charities (LCC). The group is composed of therapy dogs across the country, and those that arrived were from as far away as Nebraska and Illinois.
