Booties? Or boots?
Context:
Most champion sled dogs are not pure husky: in fact, the “Alaskan Husky” isn’t really a breed at all: it’s a mix of various breeds. Although not pure bred, every sled dog must be carefully bred for life on the trail. The dogs need heavy coats to protect them from the cold, and tough feet to prevent injuries. Unlike the tough dogs in the movies, dogs with softer feet wear booties when they run.
What is "booties"? Isn't it "boots"?
