Estrada and his friend Vincent, along with Estrada's two dogs, Barnabas and Köelsch, had gone for a leisurely hike through the forest around Estrada's house.
Fifteen minutes into the hike, Estrada spotted something next to a stream at the base of a steep slope.
"At first I thought it was a trash bag, so I was actually frustrated," Estrada told The Dodo. "Nobody wants people dumping trash in the forest. Then I looked closer, and I saw that it was Sage."
Estrada's heart sank - Sage was tucked inside a small cove right next to the stream, and she wasn't moving. He was sure she was dead.
"I just said to myself, 'Oh no,' because now we'd have to do body recovery," Estrada said. "On top of that, I'd have to tell her family, and be the bearer of bad news."
As Estrada carefully descended the slope, his friend called out to him. "Vincent noticed that Sage picked up her head," Estrada said. "He yelled, 'Dude, she's alive.'"
