I don't know many of the details, but for those who cannot read it on Facebook:
Apparently they got a call that Party was in someone's backyard eating food from the hand of a woman who works for animal control. Party's handler went there, called her, and Party ran right to her, wagging her tail and licked her.
She appears to be no worse for wear--just dirty and covered in ticks.
What a great way to end the evening!
