She was brought to the Humane Animal Rescue’s North Side Animal Resource Center in Carnegie and they were able to find a microchip during the initial exam, which they traced back to her owners in Boca Raton.

The owners were in ‘disbelief’ when they were contacted by staff at the Humane Animal Rescue.

“I can’t believe you’re calling me right now. I can’t believe this is happening,” said owner Katheryn Strang.
