I have been doing a lot of traveling recently and spent some time in the Little Rock, Arkansas airport. I was noticing a few ladies walking some dogs with blue vests, so I visited with them and found out they are therapy animals. "Bow Wow Buddies are trained and certified therapy dogs who walk through the airport to be pet by anyone, especially those anxious for their flights. The experience calms passengers or those who just need a furry friend to play with."
I found this news clip about them, so please enjoy!
