If you feel you are ready one day to welcome muddy paws onto your furniture (I say that lovingly), please adopt. This story about a dog that survived Euthanasia recently should have done wonders for educating people about how quickly a dog will be killed after being surrendered by their owner, simply because nobody wants it (two weeks!).
Only dog lovers can really appreciate and understand what it's like to live with dogs -- and the lessons we can learn from them. I believe that their average life span is shorter, because they don't need as much time as humans do, to get everything they need out of life. They understand gratitude and appreciation. They know how to forgive.
