The holidays are a wonderful time of year, full of excitement , expectation, and celebration.

But for many it's also a difficult time. This is especially true for anyone not blessed with a close, supportive family, or those physically separated from loved ones.

Consider, among these unlucky souls, the four legged ones who have to spend their holidays--all of their days, in fact--at the local ASPCA or animal shelter. These poor creatures have little to look forward to besides hoping that some nice family will adopt them some day.

Pets need new games, new toys, new smells and experiences, and above all, exercise to be happy. Dogs and cats in shelters can get depressed, lose their appetites, and become more susceptible to illness.

I was pondering this recently, when a light bulb turned on in my head (figuratively, not literally). "Why not get all these lonely and stressed-out souls together?", I thought.

Now, I'm not implying that everyone who's feeling a little despondent or stressed during the holidays should run out and adopt a pet. Bringing home a new dog or cat is a serious commitment and should be done for the right reasons, and with plenty of forethought. But there are other ways to bring the gift of good cheer.

A lifting of the spirits is not only a rewarding gift to give, but is good medicine for animals and people alike. A happier animal is a healthier animal, and probably a more adoptable one. And a happier human is not only healthier, but more apt to enjoy the season of giving.

What could be more uplifting for both dog and human than bringing some inexpensive "kitty or doggie gift baskets" to a local shelter, and watching the residents enjoy them? You -- or the "holiday-challenged" people in your life-- could fill up a basket (or two, or three!) with healthy pet treats, amusing toys, or comfy blankets. You might want to check first to see if the shelter in your area allows this, or if they have a need for particular items.

If cat or dog gift baskets aren't an option, offer to take a canine resident for a walk. I recently learned about a retired couple who does this on a regular basis. They spend their entire day at the local shelter, making sure that every single dog has been walked. The couple does this twice a week, all year round. The dogs love it, and it's wonderful exercise for all concerned.

I know what you're thinking. But you don't have to do anything as time-consuming as all that. Just show up once or twice. A walk and some fresh air is a great way to alleviate holiday stress and you're sure to catch some of the light-hearted spirit that radiates from a happy dog. Tell a friend about it. Maybe they'll give it a try. Some might be inspired enough to become "hometown heros", like the couple mentioned above.

You might know an older retiree who considers dog ownership too much of a burden, but wouldn't mind taking a dog for a walk. If it's a friend or family member who walks but no longer drives, perhaps you could volunteer to drop them off and pick them up.

Giving freely of ourselves is one of best gifts we can give. But if all of this seems too time consuming, then a small financial donation would still go a long way. Lots of shelters have fund raisers this time of year, and odds are you won't have to look far to find one. In the end, caring is what really matters.
