With winter now in full swing, Britain's huskies are preparing for their biggest event of the year at the 30th Aviemore Sled Dog Rally this weekend.
Organised by the Siberian Husky Club of Great Britain, the race will take place on Scottish forest trails around Loch Morlich in the highlands.
Over 250 mushers and more than 1,000 dogs are expected to be in attendance at the event, which began with a 12-sled race at the inaugural rally in 1984.
Mushers will run sleds of between two and eight dogs around the course, with three-wheeled 'urban sleds' on standby in case there is not enough snow on the ground.
While certain breeds of dog are well adapted for the cold weather, pet owners would be wise to keep an extra close eye on their animals as temperatures plummet, making sure they are not left outside for too long in order to prevent them from losing too much body heat.
