The 'little guy' who is pictured to the left is a deep sea creature, recently discovered. Here is a link to an article about more 'far out little guys."
My very first background picture showed 'Missy,' a wild dog living on the Blood Band Indian reservation in Southern Alberta, Canada. She rarely allows people to get within more than 5 feet of her, but she loves going for walks and 'hanging out' with people and other dogs in our band. I am thrilled to report, that she was spayed a few months ago. She'd had a littler of many pups, every year since I can remember meeting her: 5 years ago. Her suffering and that of her unwanted puppies has finally ended. She really has a beautiful personality and is a delight.
