Ask us why we love our dogs

So one day last week I asked my daughter Jessica if she would walk partway to meet me as I walked home from work, and if she would bring my dog, Indy, with her. This would give wild man Indy a nice walk, and spare tired me from having to walk him after walking to and from work that day.
When I stepped outside it was about 20 degrees colder than I expected. That, and looking forward to meeting up with Jess and Indy, added speed to my stride.
I saw them from a distance, Jess in a pink sweater, pink-cheeked, long hair floating on the wind. Indy was a fluffy gray cloud on springy legs, tugging at the leash, eager as always to take in the whole world simultaneously.
Crossing to their side of the street, I waved at Jess until she spotted me. As I reached the curb across the street from them I called "Indy!" He was busy watching the car coming up the street, which stopped at the corner, blocking our view of one another.
As I waited for the car to pull out I thought about how I'd been hoping that Indy would be excited to see me coming up the street. Now I thought, he's so wired about being out for a walk he'll barely notice me.
But as the car pulled away and I gave it one more try, calling "Indy!" I saw his head snap up and his attention focus on me as I crossed the street. As I approached I could hear him whining as he danced on his hind legs, trying to get to me.
Jess and I "aww"ed as Indy leaped up to nuzzle my face. I felt like a war hero returning to cheering crowds and a ticker tape parade. I felt like exactly what I was: the center of Indy's life, the center of his heart.
I'm always going to remember that moment when I hear anyone wonder aloud why some people love their dogs with such ardent devotion.
Not since my children were small have I been greeted with such unrestrained enthusiasm. Dogs not only let us love them as much as we want to, they thrive on it. The more time, patience, affection and care we offer them, the more we receive of their love, devotion and undiluted displays of joy at the very sight of us.
I hate taking Indy outside to pee when it's bitterly cold or pouring rain. He has a shrieking bark that could shatter glass, he's a pain in the ass to walk and he's so jealous of my cat Sadie that he comes running every time he hears me talking to her.
He also runs to the window to catch a last glimpse of me whenever I leave the house, glues himself to my side whenever I'm home, and presses his head into the crook of my neck whenever he sees me crying.
And my every homecoming is a joyous ticker tape parade.
