DFO’s Critters — Frosty Dog
Bonnie Borba's sled dog Zathras licks its frosty face after taking a 10-mile training run on the Alaska Dog Musher's Association trail system Thursday in Fairbanks, Alaska. Borba is taking advantage of the warmer weather to get in as much training as she can before the temperature drops again, adding that the cut-off for running her short-haired sprint dogs is 20-below.
