Cecil, how can dogs walk around in snow and subzero weather without getting frostbite on their feet?

Heading up the do-not camp was Stuart Nelson Jr., head veterinarian for the famous Iditarod dogsled race currently under way in Alaska. This 1,100-mile event lasts two weeks and features several dozen dog teams and their mushers racing from Anchorage to Nome in some of the most grueling conditions imaginable. The temperature falls to 40 below (at which point, I might note, Fahrenheit and Celsius thermometers read the same). Dr. Nelson says he’s seen lots of frostbitten canine parts, including the nipples, uvula, and prepuce–no wonder the Iditarod has been condemned by animal-rights groups.

For years I’ve heard that nickel-cadmium batteries which are not fully discharged will “develop a memory” upon recharging, and–after a time–if they are only partially used each time before recharging, eventually the full capacity of the battery will not be available. Is this true? –Hobberstad
