days of dogs

I spend my days with dogs, which, you would think, would satiate my appetite and leave me fulfilled in the "having a pet" area. Instead it does the opposite. I spend hours looking for dogs to adopt online, and recently I found a dog named Roxy. She was on there for awhile, and I stared longingly at her picture and read her caption over and over. Then she was gone... She got adopted. It was like somebody had stolen her from me. Yes, I have never met her, but looking at her picture so many times makes it feel like I did. Well today, like usual, I went on to sbdawg.org and saw her picture again! She is back. I know I should be sad because she doesn't have a home and I can't give her one for awhile, but instead, I am excited.
How can I not be?
