A diamond-studded collar is worthless if your pet doesn't have an identification tag attached. The only time to take off your pet's collar is when you are giving him a bath. Put it back on before he's dry.

2. Train your dog.

Teach him he's not allowed to leave home without you. Find a local trainer who will assist you. The Association of Pet Dog Trainers (800-PET DOGS) will help you locate a trainer that is right for you and your dog.

3. Keep a padlock on all gates.

This can discourage theft. But remember, it is only a momentary inconvenience for a thief.

4. Never leave your dog in the yard where he can be seen.

This is like window shopping for the thief.

5. Always walk your dog on a leash.

According to the Association of Pet Dog Trainers, "Even a dog who graduates at the top of his obedience class can become scared, distracted, or tempted. And in a moment he can be hit by a car or lost forever."

6. Don't leave your dog in the backyard when guests or service people have access.

You can't expect anyone to be as diligent about keeping him in or as concerned about his getting out as you would be.

7. Never leave your dog unattended on the street.

A dog left hitched to a tree, lamp post or parking meter looks like a wallet full of money sitting on a sidewalk to a thief- and just as easy to steal.

8. Protect your dog from loud noises.

Fear is one of the most common reasons for why a dog runs. Loud noises are usually the cause. It can be a firecracker on the Fourth of July, a thunderstorm or even a backfiring car.

9. Teach children to keep gates and doors closed.

Sometimes this requires practice, but it's a lesson well worth learning. It's also a chance to teach children about the responsibility of caring for a pet.

10. Spay or neuter your dog.

Even the most loyal dog will leave his or her happy home when love is in the air.
