Has anyone tried using Garlic in their dogs diet to combat fleas?

Garlic is on the list of toxins to dogs but I have heard others say it is good for dogs.
But it is suppose to be safe if it is cooked but then that depletes the purpose somewhat.

From time to time on ThriftyFun, Is Garlic Good or Bad for Dogs? the community debates whether garlic is beneficial or harmful to dogs and cats. With the pet food recalls, an increased interest has been created with homemade pet foods and pet health.

A quick survey of the internet shows many sites that talk about onions and garlic and being poisonous, even deadly to cats and dogs. On the same page, you will see ads for "Natural Garlic Supplements For Dogs" and sites that recommend garlics for flea prevention and general well-being. It is hard to know what to think.

Here is a pet health site from the American Animal Hospital Association that discusses poisons.

* HealthyPet.com - Prevent Poisonings
Welcome to Healthypet.com!

Toward the bottom of that page, there is a specific list of poisonous materials. It lists garlic and onions as poisonous, even deadly, but only in a raw or spoiled form. So does that mean that cooked garlic is OK? What about garlic supplements that people are selling for pets?

We'd like to know what you think! What have been your experiences with garlic? What has your vet told you? Has anyone lost a pet due to garlic poisoning?
