My dog Asha is the best dog ever - she has so many friends. But she is 12 now - what is that 84 in dog years? Though she is healthy, I guess she doesn't have much time left. She has taught me a lot in her short life. Here are a few of the lessons:

Belonging: The pack is essential. Our belonging to it is a part of our identity. A lot of our problems can be traced back to the fact that we aren't really a part of a pack.

Daily Routines: Early on, Asha taught me the importance of a daily routine that included a morning walk and then a trip to the office. There she made her rounds and greeted all those in her pack.

Alignment: When we walk together, she checks in every 10 seconds or so, looking up at me for her cues. She teaches me to do the same thing with God.

Consolation: When someone is sick, she senses it and ministers with presence, sitting close to them or on their lap.

Eye Contact: She has a soulful stare, reminding you how important connection is.

Attitude: She's always the happiest one in the room and checks in to make sure others are happy too.

When I've been away on a trip, Asha still gives me the kind of greeting that says, "Master, I've missed you so much. You know that I've been looking out the window for you every day. I knew that it was my job to guard the house and protect the pack in your absence and now that you're back, we can share that job."

Loyalty is rare these days. If you've ever had a loyal dog who acted like you were the most important thing in her life, and if you ever dreaded the day that you would one day say goodbye, then you know what I feel when I contemplate the way I see her aging.

Studies show that having a dog is one of the best things you can do for yourself as you get older. Those of you who have had one like Asha, what has been your experience?
