It would be easy to 'not believe the hype', or think it's 'too good to be true'. You can be the judge of that, but these are my experiences. I bought the 32oz on a whim, hoping it would at least make an improvement to my situation. I bought a house from a dog owner, with some problem areas. I also have two dogs that have had a few accidents from time to time. Not only did this product correct my dogs lingering smell & stain issues, but it took out other stains in the carpet that I had tried numerous times with numerous products to get out. This stuff is amazing. I would recommend it to anyone with or without a pet.
