Kicked and slammed to the ground by her owner, shattering her back leg, doctors weren't sure if Callie the pit bull would ever walk again in January.
Fast forward to almost a year later, Callie, now known as Abby by her new owner, is healthy and entirely healed.
Maria Johnston adopted the pit bull, nursed her back to health and recently completed her training to be a therapy dog.
"Amazing. I probably would not have believed that we would have come this far, quite honestly," said Johnston.
Even Abby's trainer was impressed by the dog's incredible journey.
"She is very loving, and for all the abuse that she went through, she has come such a long way," said trainer Ann Walker.
Abby became an instant hit at Green Meadows, an assisted living community in Latrobe, Westmoreland County.
"She makes you feel good. You just feel like it's a good day whenever they're here," said resident Mary Ann Hurite.
Fellow resident Bertha Achtziger said Abby has made her feel alive again.
"They just make you feel so good. Animals just do that to you," said Achtziger.
Johnston and Abby plan to become regulars at Green Meadows.
"Just if we run out of cookies, then she might not do what you want her to do," said Johnston.
