i used to buy frontline for my dogs but i never liked using chemicals on them then i heard about garlic and brewers yeast and decided to give it a try.
i bought the brewers yeast w/garlic that also had vitamins and nutrients and it worked fantastic.
i have 4 american eskimo's and there is not a flea to be found, their fur has never been softer or shinier. they have more energy and all in all i have noticed a big change in them for the better.
only problem is you need to start it before “flea season” and don't stop. i ran out and didn't start again for a week and they started scratching and it took another 3 wks. to get flea free again.
i use the tablets and just mix them, whole in their food. my youngest 2 love them.
