A friend of mine who breeds Corgies recently recommended this product for fleas. He lives out in the woods and he said that his dogs never had a problem with fleas. Not sure if that is what it's meant for. I have tired natural/herbal remedies for my poodlemix but these past few months it wasn't working. Since getting the product my dog has been eating up his food like crazy. Before he would just nibble here and there. My dog really likes this stuff, so I am happy that he is eating well, better than before. Not sure if it's working for the fleas yet.
