Many may not know, but most UPS drivers are huge dog lovers. There's even a Facebook Page called UPS Dogs where drivers post pictures and stories about the dogs they come across on their routes.
It was on this Facebook page that we first heard about Katie and Leo.
Leo, is a pit bull that used to live with a woman named Tina. Her son, Cannon brought the pup home with him one day and it was clear that the pup was too young to be away from his mother. Tina bottle-fed him until he was able to eat regular food. This formed an unbreakable bond between Leo and Tina.
Tina was not the only one that Leo bonded with. Katie the UPS driver from Rancho Cucamonga, California came across the pup on her route.
"He would hear my truck come into the condo complex and start barking and scratching at the door to come down to the truck. He would love to come into the truck and go into the back to look around," Katie said.
Not everyone felt comfortable around the dog though. People in the condo complex were nervous to be around the dog, because they believed the sigma surrounding the pit bull dog, and Tina was forced to muzzle him when he was outside.
"I remember one day I was driving up one of my busier streets and they were coming down the street and all of a sudden there was Leo popping his head out the passenger side barking at me! He barked all the way down the street!" Katie said.
Everything changed last October when Katie returned from vacation to discover that her friend had passed away.
"I pulled into the complex and saw Cannon pulling out with the back of Tina’s truck loaded with furniture. I thought that she had found somewhere else to live. I waved and he waved and I didn’t think anything of it. I tried to call her later that day and her phone went right to voicemail. I tried the next day and the same thing. I looked on her FB page and there were condolences and comments about her passing away. I was in shock," Katie said.
