Luna, a 10-year-old Jack Russell terrier, walked into a live trap in Yellowstone National Park on October 14, 2026, 34 days after she slipped out of her family’s cabin. The bait was scraps of a T-shirt and a pillowcase that belonged to her family. Katie Boucher, the volunteer who led the search, said strangers calling Luna’s name and running after her set off her fight-or-flight response. Each time, she went deeper into the park. Luna was underweight but alert when Boucher took her to a veterinarian, and she has been reunited with her owners.
How a cabin door became the escape
On September 10 the family left Luna in their cabin with a “Do Not Disturb” sign on the door and went out to explore the park. Housekeeping apparently opened the door by accident, and Luna got out. According to Boucher, staff chased her around that part of the park for more than two hours before the owners came back and found her gone.
Yellowstone’s pet rules say a pet may not be left unattended, and the park has no kennels, though boarding is available in the towns around it. If a dog has to stay in a room anywhere on a trip, a closed crate keeps it inside even when someone opens the door. Telling the front desk that a dog is in the room, and asking for no cleaning while you’re out, covers the rest.
A dog lost far from its neighborhood
A study by ASPCA researchers, published in 2012, surveyed 1,015 US households that had owned a dog or cat. Fourteen percent of their dogs had been lost at least once in five years, and 93 percent of those were found. Neighborhood searches and dogs wandering home led the list. Only seven of the 110 lost dogs turned up at animal control or through the police.
A dog lost on its own street knows the area, and the neighbors know the dog. Luna had neither in Yellowstone, which covers about 3,500 square miles. Her family was told she had probably died, possibly killed by a coyote, and they heard she had been spotted only days after they left the park.
Boucher runs the Norris Ark Training and Recovery Center in Norris, Montana, just north of the park, and she tracked the sightings. By her account, Luna was retracing the steps the family had taken the day before she was lost, slipping into the eateries and lodges they had visited. People saw her crossing intersections, walking through employee housing and going into lodges through automatic doors.
The park rules that keep a dog out of trouble
Yellowstone allows pets only in developed areas, within 100 feet of roads, parking areas and campgrounds. A pet has to be in a car, in a crate or on a leash no longer than six feet. Pets are banned from boardwalks, hiking trails, the backcountry and thermal areas, even when carried in arms, a stroller or a backpack. The park’s reasons are predators such as bears and coyotes, hot springs that burn and kill, and diseases that pass between pets and wildlife.
The park also lists plants in its campgrounds and developed areas that are toxic to pets, including common yarrow, water hemlock and larkspur. If a dog eats one, the park’s advice is to get veterinary care right away.
In the ASPCA survey, an ID tag was how about one lost dog in seven got home. Before a trip, put a tag on the collar with a cell number that works on the road.
The trap, and what it left out
Boucher’s volunteers set a live trap baited with the family’s scent. They kept food out of it on purpose, because food could draw bears and other wildlife into a park home to grizzlies and wolves. Missing-dog flyers with two photos of the white, short-legged terrier went to anyone who might see her.
If your dog bolts somewhere unfamiliar, stop chasing and calling it, and ask the people around you to do the same. Write down every sighting, walk back through the places you visited together, and hand out flyers with photos. A recovery group can set a trap baited with clothing that smells of you.

Boucher said Luna had spent her first year on the streets before she was adopted, and her survival instincts showed. Boucher said this was the last week she could have searched. Colder weather was coming, and the RV park for seasonal workers where she was sleeping closes on Monday, October 19.
