We have always had "rescue" pets. 

We had a beautiful greyhound for ten years that had been bred and used for racing.  When she was injured and retired at 18 months her owner put her up for adoption.  Other greyhounds are not as lucky- many are killed. 

At the moment we have a Yorkie that was rescued from a shelter in Florida.  She has brought more joy to our home than words can express. She quietly curled up in our hearts and we will never be the same.
