A black Labrador named Tokyo is rescued by mountain rescuers after becoming ill partway through a hike on Ben Nevis, the UK’s highest mountain. The dog’s owner, Christina Bluhme, was ascending the mountain to reach the summit at around 4,413 feet when Tokyo suddenly showed signs of distress and collapsed during the climb. Rescuers respond to the incident and recover the animal, and the dog is treated for suspected causes linked to what she may have eaten while on the route. Multiple reports describe the dog as having suspected cannabis ingestion from discarded material, rather than illness from other causes, based on the circumstances of the hike and the symptoms observed. The incident highlights risks in outdoor environments where litter may be present on popular trails. The dog’s condition improves following the rescue, and the event draws attention to the need for care around discarded substances in remote areas.
