My dog Sienna. Age, 12 years. Has an excruciating case of arthritis in her hips.

She was there when I got married, there when I brought home my first baby, there when I brought home my second baby. She has kept me warm on cold nights, snuggled up to me when I've cried. She is a good sport with my kids (despite the ear and tail pulling). Is always up for a walk....anytime day or night. She keeps our kitchen floors clean. Once, she fought off a mean dog who came running towards my daughter.

She has a young and happy heart. But an old and failing body. I don't know how much longer she will be here with me. But I do know that Sienna, my old friend, has been a HUGE part of my life and I love her with all my heart.
