Bluhme said she felt “incredibly lucky” that Tokyo had survived and thanked the rescue crew and vet team for their “compassion and dedication”.
“You were there when we needed you most,” she added.
“A little reminder to fellow dog owners – please be aware that discarded drugs and other toxic substances can sometimes be found even in the most beautiful outdoor places.
“It was something I never imagined we would encounter.”
Lochaber Mountain Rescue Team said it was pleased that Tokyo had made a full recovery and praised the local vet team in Fort William.
A spokesperson added: “It’s now suspected that Tokyo, a usually very fit and active working dog, had ingested something that made her critically unwell.
“Many thanks to Crown vets for their support, and to Tokyo’s owner for the update and photos.”
