It seemed to work for my puppy while he was potty-training. He was struggling to control his bladder for the first few months and I was worried about the lingering smell and stains on our floor. But after a few times, he would stop urinating on the same spots and eventually altogether. We have a vinyl flooring so i was less concerned about the staining on the floor. But the pup did make mistakes on our small couch and this product effectively removed stains and possibly the odor. It also has a resfreshing scent that is on the strong side at first but dissipates quickly. The nozzle turns for spraying and squirts which I found convenient and also off for safety. I am happy with this product and it helped me deal with the pain during the potty training process.
