What I'm referring to is that kind of "Wow! He's so handsome!/She's so pretty!" moment people typically have for other humans that genuinely catch their eye in the moment. Maybe it was something about the look of their coat or the shape of their muzzle, but when you saw it you had to take a moment to really admire them for a moment and figure out what drew you to them.
The first instance this fully hit me was when I was hanging out at a friend's place for the first time. He had a couple of Huskies, and one of them had this beautiful pure white coat like I'd never seen. That alone was lovely, but there was just something about his eyes that stood out to me. I still don't really know exactly what it was. Maybe it was his brow or the general look about his face, but to this day, almost a decade later, I still think back to that beautiful, handsome, and striking pure white male husky chilling or strutting about with his head up. I'm extremely thankful to him for really opening up the full array of emotions I feel towards animals.
