"People she works with, acquaintances and perfect strangers have out scouring the woods, looking along the side streets," Barb Kurpiel said.
This morning, they were in Mom's Ford Escape cruising around the town of Emmaus, about eight miles south of the ballpark, chasing a lead.
But no sign of Champ.
"We have been looking except for a few hours of sleep for the last three days," said Mom.
"We've seen deer, possum, a couple of cats, lots of rabbits ... no dogs, no stray dogs at all," said Janine.
Ironically, the Phillies World Series trophy played a role in Champ's getaway.
The gates opened several hours before Friday's 7 p.m. game, so fans could pose for pictures with the trophy.
That promised to make a long day for Champ, so the grounds crew offered to keep him in an office.
But someone opened the door as the post-game fireworks were going off, and Champ, who gets spooked by thunder, just ran, sometime around 10:30 p.m., Janine explained.
"He's a Shepherd mixed mutt," she said. "He's between 40 and 55 pounds. He has a purple collar on, and he's brown with some black on his back, just a little bit. He's 4-1/2 years old."
There's no way to know where he could be, because dogs can roam pretty far.
"Sometimes they're right around where you are, sometimes they're 30 miles away," Janine said, citing a conversation with the Lehigh County Animal Response Team.
Her bosses - general manager Kurt Landes and team president Chuck Domino - have been very supportive, letting her come in late and leave early, to keep searching, she said.
"They know how much Champ means to me, and therefore he means a lot to them," she said.
"The response from everyone has been so amazing," she said.
Anyone who has seen a stray dog resembling Champ in the Allentown area is asked to call Janine Kurpiel at 610-554-0474.
Whoever finds Champ can expect VIP treatment by the Lehigh Valley IronPigs, as well as a not-yet-declared reward, she said.
