Brewer's Yeast with Garlic as a natural flea remedy

[Anonymous]

I've just purchased Brewer's Yeast with Garlic as a natural flea remedy after reading "Eliminate Fleas withough Poinsons" and "Are Spot-on flea killers safe?". I've searched the different options to replace Frontline and decided to try Brewers Yeast with Garlic, although now I'm wondering if that's safe, as I've read that garlic can be deadly for dogs. Is using Brewer's Yeast with Garlic a safe alternative to Frontline?

I recently asked a local holistic vet about the safety of Frontline and alternatives. Her shocking response was that Frontline is not a pesticide and that it is safe because it has been around for such a long time. Fortunately I knew to walk away and not return to her for future advice!
