The Labrador community of Nain issued a boil-water advisory Friday morning after two teenagers found a dead dog in the water supply a day earlier.
Jacqueline Winters said she and her friend spotted something in the water Thursday afternoon while they were fly-fishing.
Winters said they only realized it was a dog once they dragged it closer to shore.
"The dog had cuts around her collar and on her face, it was pretty bad looking. She looked like she'd been there for some time, too," she said.
Winters said they contacted the town immediately, but a boil-water advisory wasn't issued until Friday morning.
Mayor Tony Andersen told CBC News he put out the notice as soon as he could.
It's still not known how the dog died or how long it had been in the pond.
