Why do Borzoi have long noses?

Borzoi have super long noses, or snouts, primarily due to their evolutionary adaptation as sighthounds. These dogs primarily rely on their keen eyesight to track and chase prey, and their elongated muzzles mean they can spot prey better than breeds with shorter noses.

The long nose also accommodates a larger nasal passage and more sensitive olfactory receptors giving them better hunting direction and allowing them to take in more air with each breath, which is essential for maintaining stamina during long pursuits.
