My German Shepherd Dog (Qanuk) was a bit peeved that I forced him to sit still for even just the 20 seconds it required for me to get an image of his ‘ice beard’. We’d been walking for maybe 15 minutes and heading back home to hold the total walk to less than 40 minutes as it was -12.7 F. Because Qanuk is extremely active even in these temps he has to pant heavily from his exertions and due to the relative cold, dry nature of the atmosphere his exhalations quickly freeze around his muzzle
