Working for me and my not so trained puppies.
Ive used Expel all over my house and so far my pups have not peed in the same place twice. It doesn't keep them from peeing but I knew that it wasn't meant for that. Also, I've used it on my sons carpet and no more stinky boy smell; and my father inlaws room and it took care of the smoke stank. I love it and will continue to use it.<br /><br />One more thing, it was recommended by my dogs trainer. They use it in their kennel areas and office.<br /><br />UPDATE!!<br />I wanted to advise people on how well I think Expel has worked for us and our potty training pups. After using Expel while mopping my floors our pups have not had an accident in almost a week. I use it every other time I mop so that there isn't any lingering odors and I really believe this is why we have not had any accidents. I keep it in a spray bottle and spray while I mop. This has become one of my fav cleaning products.
