It just keeps snowing and snowing and last week it got colder and colder and colder. One morning when we awoke it was -20° and we needed to go out. Living in the city, with brick sidewalks that hold the cold and are covered with salt, make it very painful for Sophie. She would limp and hold up her paw. I would end up picking her up and carrying her to her favorite patch of grass, which is covered with two feet of snow. We finally stopped at the pet store down the block and walked home with new red boots.
At one point, I looked down and she only had on three boots—damn. We backtracked and there in a snow bank was the fourth boot. After this happened several times, the boots had to go back.
We're now using MUSHER'S wax just like the sled dogs in the Iditarod and it works great.
