I'm on my last bottle and this time I'm ordering a gallon since I can't seem to get my young Yorkie refuses to use a pee pad and ask to go out. She has 3 older one to follow and still doesn't get the hint. The first time I ordered I had my doubts but she had a loose poop and I sprayed it on and I went to see if I needed to scrub and it was completely gone I couldn't find it and I didn't use much! Amazing and worth every penny.
