A woman suffered third-degree burns after attempting to rescue her dog from a Yellowstone hot spring

• A woman was left with third-degree burns after trying to save her dog from a Yellowstone hot spring.
• Ladonna Slayton, 20, was touring the national park with her dad when the incident occurred Monday.
• The dog, Rusty, died from injuries and Ladonna could remain in a sedated state for 3 weeks.

A 20-year-old woman could be sedated for up to three weeks in hospital with third-degree burns after she attempted to save her dog when it ran into a scalding hot spring in Yellowstone National Park, her sister Kamilla Slayton said on Instagram.

Ladonna Slayton of Washington State was visiting the area with her father on Monday when her dog Rusty "got away," and was burned by hot water from a geyser, Kamilla said in the description of a GoFundMe page she started on behalf of her sister.

Spooked from the hot water, Rusty ran straight into Maiden's Grave Spring, a hot thermal spring with waters reaching temperatures of up to 200 degrees Fahrenheit, according to a news release from the National Park Service (NPS) published on Wednesday.

Providing further details about the incident, the release said Ladonna entered the spring to try rescue her dog, resulting in her suffering from severe thermal burns. In a GoFundMe post, Kamilla said that her sister's "palms are completely gone" and that Ladonna has third-degree burns on 90% of her body from her shoulders down.

While attempting to save his daughter's life, their father also suffered burns on his foot, according to the GoFundMe post.

After NPS rangers reached the pair to provide initial treatment, according to the release, Ladonna was then transported to Eastern Idaho Regional Medical Center, where her sister said on Instagram she has undergone several surgeries. In the same post, Kamilla shared texts from what appears to be a family member who said Ladonna had received temporary cadaver skin to "hopefully help her heal."

Rusty, who the Daily Mail reports was one of two Shih Tzus on the trip, is said to have since died from its injuries.

On Wednesday, Kamilla posted an update to Ladonna's recovery on Instagram and said that following a second surgery she has "had a great night and morning."

"She is stable and healing slowly and at a good rate," Kamilla wrote. "This won't be a fast process by any means."

She also said that their father is not in any pain but that the 1.5-inch blisters on his foot are being treated. Ladonna's other dog, Chevy, is "handling things well, all things considered," she added.

Kamilla started the GoFundMe page on Tuesday with a goal of raising $45,000 to help her family afford medical treatment for her sister and father.

"The vet bill, my sister, dads medical expenses are something that my family can't afford right now," she said in the page description. "Not only that, but my parents have to stay out of state for a few weeks to a month depending on her recovery. They will need help with food and lodging, and cremation services for her puppy."

Over $25,000 has been donated at the time of writing.

Kamilla Slayton and the National Park Service did not immediately respond to Insider's request for comment.
