Incredible footage shows the moment when a dog sniffs out a 'lost' person, who has become 'buried' under snow.<br /><br />The impressive actions of SD Hope are part of a training exercise to prepare search and rescue dogs for what they would likely encounter during an avalanche. <br /><br />Dogs and their handlers from Mountain Rescue Search Dogs England took part in a training week in the Cairngorms. <br /><br />A social media post reads: "Although our dogs don’t work regularly in avalanche prone areas (although with enough snow anywhere can be), there are many areas prone to large snow drifts forming. <br />It is not unheard of for people to be buried in their cars during snow storms. This helps familiarise the dogs with the skills needed find people in this situation."
