Anyone have a dosage for using garlic as flea control?

Someone told me putting garlic powder in a dog's food was good for flea's. Has anyone tried it? How were your results?

Okay, Inever ever feed Nina garlic. The majority of her veggies are apples carrots and parsley, i feed her bananas occasionally with the peel. Yet I read garlic in the ingredients in a lot of dog treats, even some of the dog food I feed her ( Acana, Orijen).... so what gives?

I Am Thinking About Changing Sadies Food To Innova Evo But One Of The Ingredients Is Garlic And A Vet Tech Friend Of Mines Vet Told Her That Garlic Wasnt Good For Dogs And I Just Wanted Some Other Opinion Because Alot Of People Have Different Opinions. If Anyone Is Currently Or Has Fed Innova...
