When you think about it, dogs need very little from us to make their lives happy: a nice home, a little love, some nutritious food and exercise. Not much when you think about it.

When I saw an excerpt from the book "It's a Dog's World: A Savvy Guide to Four-Legged Living," by Wendy Diamond (Ballantine Books), it made me think about how simple it is to give a dog a good life. And how simple it is to help a dog. Diamond, whose book is being released this week, writes about hoping to motivate dog-friendly readers to become involved in animal rescue and helping on several levels.

Many local humane societies, she says, have small budgets and rely on volunteers and donations (money and supplies) to keep going.

She lists 10 ways people can help dogs in need. A few:

"Consider being a foster parent to pet in transition. There are many local organizations that specialize in placing animals in loving, temporary homes.

"Use the power of your vote! Let your local and state representatives know that caring for animals is a priority for you. Write an email that clearly states your views and forward it to your friends and acquaintances to pass on.

"Be vigilant! Pay attention when you see signs of animal abuse and report suspicions to an animal protection agency.

"Consider adoption and check out your local shelter. Many of these animals have suffered terribly and desperately need your love."

I know that my local animal shelter is happy to accept donations. When our dogs are through playing with their toys or turn up their noses at certain food, the animal shelter will accept them.

If you love dogs, think about ways you can help. They need so little and give us back so much.
