You know I'm interested in dogs, obviously😀. What I always find interesting is which dogs are the real athletes. For example, when I saw the iditarod dogs up close, these were not big, beautiful Siberian Huskies with luxurious coats. When you're out there in the cold you don't care what the dog looks like. They call most of them Alaskan Huskies, but these dogs are thinner, more wiry, and more heavily muscled than any show dog. They are usually a mix of northern breeds. I used to do Schutzhund, and the same rules applied. Thin, not so beautiful dogs were the best. Nobody wanted a US bred German Shepherd. They imported working GSDs from Eastern Europe.
