HANOVER — A woman was hospitalized Tuesday with hypothermia after she braved the icy Connecticut River to save her dog, Marshmallow.

Marshmallow is half sheltie, half basset. She has really short legs, and is funny looking and sweet, her owner, 48-year-old Suzanne Schon of Hanover, said Thursday afternoon after returning home from a two-night stay in the hospital.

Schon had been walking her four dogs Tuesday on a trail along the river’s shore when Marshmallow walked out onto the partially frozen river.

“One of the dogs had gone out on the ice and fell in and couldn’t get out,” she said. “I foolishly went in without calling anybody first.”

Rescuing her dog was an arduous task, she said. “I had to do a lot of ice breaking to get to her.”

When Schon finally got back to shore with Marshmallow, she passed out, she said.

“A couple of hikers came upon her on the embankment and realized she had fallen in the river and she was wet,” said Police Chief Nicholas J. Giaccone, Jr. “She was curled up in a ball on the river.”

She had been found a short time after noon, Giaccone said.

Police and rescue workers responded and she was taken to Dartmouth-Hitchcock Medical Center where she was treated for hypothermia. Schon said she was told that when she was admitted into the hospital her temperature was 84 degrees.

The medical center held Schon for two nights to be sure she was stabilized and free of the life-threatening effects of hypothermia, Schon said.

She returned home Thursday afternoon grateful to the hikers who found her and to her family members who have

“The dog is fine, as are the other three that were cheering us on,” Schon said. “And I’m glad to be here.”
