The Beard 🧘
Let's address the obvious. The Miniature Schnauzer has the most distinguished facial hair in the entire animal kingdom. While other dogs have "fur," the Schnauzer has a beard. A proper one. The kind that suggests it might have opinions about single-origin coffee or obscure philosophy.
No other breed pulls this off. The Airedale tries. The Scottish Terrier makes an effort. Neither comes close. This is the Platonic ideal of canine facial hair.
