A ski patroller shared a typical day in the life of her dog, Millie, who is training to become an avalanche search and rescue dog, and the heartwarming video has delighted viewers on social media.

The viral clip shared on TikTok earlier in December under the username @luma.randolph, shows the one-and-a-half-year-old English Lab and English Pointer mix going about her day as she trains to save lives with her human.

The poster, 25-year-old Luma Randolph from Idaho told Newsweek that she has been training Millie for the last year or so to become a working dog, taking her to work nearly every day, and they have since developed a "really awesome routine" together.

"Millie's job as an avalanche dog will be to detect any humans buried underneath the snow after an avalanche or snow immersion using her sense of smell, and alert me to the location they are buried," she said.

While training, Millie's days usually consist of morning snuggles, a well-balanced breakfast, a good walk and then attending her patrol meeting. After that, she gets to take a regenerating nap while her owner is out on missions, before coming back for obedience training and rescue drills.

Randolph explained that avalanche dogs are incredible tools that many resorts and search and rescue agencies use for snow-related rescue, adding that in situations where a victim is not wearing an avalanche beacon, these dogs are their best chance for survival.

A person trapped in the snow after an avalanche has a 90 percent chance of surviving the first 15 minutes, which quickly drops to 50 percent after half an hour. That's why according to VetStreet, dogs are among the most valuable members of the response team.

The veterinarian website states that one single avalanche dog can cover more ground more thoroughly than two dozen people with probing poles. Dogs have a sense of smell that is estimated to be about 100,000 times more sensitive than that of humans, helping canines locate people from a distance.

Pups have between 20 and 50 times as many receptors in their noses as humans do, and in ideal conditions, they may be able to smell from 12 miles away.

The video quickly went viral on social media and it has so far received over 530,400 views and 63,600 likes on the platform.

One user, TamTok11, commented: "Showing this to my two terriers with NO jobs and all the audacity."

Leuanscott said: "My pugs don't know what work is, I'm showing this to them the free loaders."

Aidanguro added: "I've never thought about working dogs getting ready for their jobs."
