Input: This product is so bad, it didn't work for my dog! I am very dissapointed. The shampoo smelled awfull and he broke out with bumps all over his body. He started scratching the worst of that product. And this was not a new product, because we had to have gotten a defective batch. Don't buy it. If you want your dog happy, use anything but this. We are never buying products by Pet Armor again,. It's too bad they dont give refunds.
Output:
Bad review
