She is named after Mt. Everest, the tallest mountain in the world.
Interestingly, Everest herself happens to be the tallest female pup.
Everest has never been seen without her toboggan.
She and Jake have been very good friends, ever since they first met in "The New Pup". Jake is also the one who suggested she come live with him on Jake's Mountain as he could use her help in rescuing snowboarders.
In "Pups Save a Pizza", she reveals she really likes pizza and helps Jake build an outdoor pizza oven Jake planned to use to make fresh pizza for snowboarders all winter.
Her tummy growls are often confused with bear sounds or thunder sounds.
She is the second female member of the PAW Patrol.
She is also the second pup to join the PAW Patrol after assisting in rescuing Jake, the first being Rubble in "Pups Get a Rubble".
Before meeting Jake and joining the PAW Patrol in "The New Pup", Everest would practice rescuing the penguins that lived near her. She mentions this after rescuing Jake, commenting that before rescuing Jake the only ones she had to rescue were local Penguins.
She has the bushiest tail out of all the pups.
Due to her highly specialized role as a snow and mountain rescue pup and the fact she lives with Jake at Jake's Snowboarding Resort, she acts mainly as a reserve member of the PAW Patrol, called in when her skills (in cold weather and mountaineering) are required.
Since living with Jake at the resort, Everest now assists Jake in rescuing snowboarders and skiers (which Jake originally did mainly by himself, with occasional assistance from the PAW Patrol) when they get into trouble on Jake's Mountain, effectively making them the resort's ski patrol.
Since they live on Jake's Mountain, Jake and Everest can rescue snowboarders and skiers more quickly than the PAW Patrol (which is primarily based in the nearby Adventure Bay) and can help take some of the burden off the PAW Patrol by acting as Jake Mountain's primary rescue team/ski patrol, allowing Ryder and the PAW Patrol to focus primarily on Adventure Bay. Should further assistance or other resources be required in rescuing people or animals on the Mountain, Everest & Jake can call upon the PAW Patrol as backup.
Everest has been first called for a mission 9 times.
Everest has been called for backup 7 times.
Everest has been called into action (either a first response or backup) 16 times.
"Pups Save an Outlaw's Loot" was the first episode where Everest is deployed in a snowless environment. It is also the first episode to center on her role as the teams mountain rescue pup and mountaineering skills. It is also Everest's first encounters with Mayor Humdinger.
This episode also reveals that she is familiar with the trail near Wild Wilbur's old cabin which proves invaluable to the PAW Patrol in their race to find Wild Wilbur's hidden loot before Mayor Humdinger.
