Blood vessels in dog paws keep their temperature just right
Web edition : 12:05 pm
When playful pups skid across an icy pond or romp in a snowdrift, their paws plunge into frosty places. If people go barehanded and barefooted in such cold places, their skin may freeze in a painful condition called frostbite. Dogs frolic without fear of frostbite, and scientists from Japan say they?ve figured out why. ?
Dog paws don?t freeze because the arrangement of blood vessels beneath the animals? skin keeps the temperature just right, the scientists report. The arrangement helps the animal hold on to body heat, which might otherwise be easily lost through their hairless paws.
