Lynn's Comments: Sheep dogs have big, wide feet, and their toes are webbed to some extent. This means that a snowy walk will result in wads of frozen snow plugging the dog's foot pads. I'd have to spread his toes and pull each chunk of snow out of the crevices--and with it, remove hair and dirt as well. It's a messy process, and the only rewarding thing about it is the look of relief on the dog's face when it's done!
