This product was recommended to my by another dog owner. She said that when she started to use it, her Japanese Chin almost stopped shedding completely. Okay. Sure. Well, call me a believer. It's not that my German Shepherd doesn't shed, she just doesn't release clouds of fur anymore. If I make sure I furminate her a couple of times a week we almost don't need to vacuum anymore. Her coat is luxurious and she is more spritely than I have seen her in awhile. This product is worth its weight in gold!
