"I had a little trouble potty training my 6 month old Chocolate Lab, and I tried several different products to deep clean and remove odor from the carpet. This product cleaned up the worst doggie mess you've ever seen. Gunner had gotten into something out of the garbage, and he had "the runs" over a very large area. The Bissell Pet Odor & Stain Removal was the ONLY product that truly cleaned every spot and removed ALL areas of the "accident". I used it in a "non-Bissell" carpet cleaner, and it worked fantastic. I also diluted the cleaner in a water bottle, to "spot clean" while Gunner was learning the difference between grass and carpeting :)"
