That's wonderful news for Lucy! If you've never had a dog before you don't know what you've been missing. Maybe you could wait a few weeks and see what dog ownership is like. You may be about to rehome the best friend you've ever had.
Sometimes gifts come our way and we don't see them as gifts initially. I can think of no greater gift than the gift of unconditional love and a warm puppy curled up at my feet.
As I type, my German Shepherd, Mary is lying at my feet, which she'll do for hours as long as I'm on the computer. There's something so comforting and peaceful having a devoted companion always at your side.
Why not give her a chance?
