The 3-year-old canine, who had an affinity for chewing on socks but was not known to swallow them whole, was rushed to Portland's DoveLewis Emergency Animal Hospital in February, hospital spokeswoman Shawna Harch said.
DoveLewis will use the prize money to fund emergency care for pets of low-income animal owners, Harch said.
The Great Dane appeared to favor lush, colored socks in smaller sizes, images of the retrieved items showed. The sock-devouring pooch's owners are keeping the hungry dog's name private, Harch said.
"His owners wish to remain anonymous," she said. "But they are getting a kick out of the award."
