Oliver, an Aussie mix we brought home from the local shelter as a puppy, had been part of our family for two years when we rescued Katie, a backyard puppy mill mom, nine months ago. Underweight, frail, and suspicious of everyone and everything at first, Katie has become the happy, healthy, and playful dog she deserves to be. As boisterous as she is timid, Oliver clearly shares the credit for her rehabilitation. He has taught her how to be a dog! They are now great friends, and we can't imagine life without either one of them.
