Why don't coyote (red fox, wolves) feet freeze in winter?

Many species that spend time in the snow have hair that grows in between the pads on their paws, giving them added warmth!

Hi Susan,

Thanks for the question. Feet have a few features which prevent them from freezing in cold weather. There is fur and the padding of the feet act as insulators. I believe the circulation changes so as to increase blood flow to the feet.

I hope this helps. Please let me know if you have more questions. Thanks Jeff
