My Sadie is the most unique, smartest, craziest best friend I ever had. No pedigree, no pretensions. She wasn't anything special to look at; she wasn't the "cute little puppy" I went to Wayside Waifs looking for.
But every time we passed her cage, she rubbed up against it to get as close to us as she possibly could. The third time back at her cage, I knew she was the dog for me.
I imagine if I had not taken her, nobody else would have. Because stuck in that cage as she was, nobody could have known her true personality.
Don't go buying some fancy, highfalutin' dog. Get one that will be eternally grateful for a home. Let one special dog (or cat) choose you.
That's what I did.
