It’s not enough to say the dog caught the eye — from the first moment Patricia Cosgrove saw her, she filled it.

When you’re a black Great Dane as big as a Buick, it’s hard to pass unnoticed — even if you’re lost and all on your own.

“I saw her long before Thanksgiving at the fireworks stand on the hill, and two weeks later I saw her in Les Gove Park,” Cosgrove said of the huge dog.

The last sighting was Sunday evening, when Cosgrove spotted the dog trotting alongside busy traffic on Auburn Way South.

“It’s driving me nuts,” said Cosgrove, director of the White River Valley Museum.

The dog has picked up a limp, and after at least two months on her own, Cosgrove said, is looking mighty bedraggled and down on her luck.

The bright news is that one of Cosgrove’s dog-loving friends has agreed to take the Great Dane, so Cosgrove has put out a reward for anyone willing to catch her.

“It’s not easy with a Great Dane,” Cosgrove said. “She’s big, and shy and nearly impossible to catch. I can’t imagine how she’s managing with the little winter coat a Great Dane has.”

And how will people recognize her?

“She creates a huge black silhouette. She’s pony sized for Pete’s sake,” Cosgrove said.
