I care for a Shi Tzu who got fleas 2 weeks within adopting him. He's one who loves the outdoors and rolling in the grass, so it wasn't surprising. After using this product, he wasn't scratching himself like crazy anymore and we've not found any fleas on him. It's not as conditioning as we want it to be, seeing as he has long hair, but he's happy and as are we. It has a light scent as well, as the owner abandoned the last shampoo for the scent being too strong.
