Campus police Lt. Greg Stone said school employees found the dogs when they arrived for work about 8 a.m. Tuesday at the barn, northwest of the main Fargo campus, the Forum News Service reported.
"They'd probably been in there for a while, because they'd done a lot of carnage," Stone said of the dogs.
Some of the sheep were dead and others had to be euthanized, Stone said. At least two others were being treated for injuries.
He said the huskies showed no aggression toward humans.
"They were just lying around, lounging, and they were good. They were good around people," Stone said.
The dogs were impounded by an animal control officer from the Fargo Police Department, the news service said. Stone said he didn't know what the dogs' fate would be but that they probably wouldn't be euthanized.
The dogs had tags but police hadn't contacted the owner, Stone said.
