I agree, yes it does really work. In fact, you may want to use it on the spots where Patra has already peed. Though it is best used when the spot is new, it will often still take out older smells & stains, too. First though, do the test spot since she has such expensive carpet.

I'd try it on an inside corner of a closet or something & follow the instructions carefully to be sure it doesn't fade the carpet color, but it's good stuff and really works. The crate is a very good idea, but if she isn't crate trained already, you'll need to procede slowly at first and check on her often to be sure that she isn't getting panic-y. When we've crated we like to put a stuffed Kong toy (frozen peanut butter & treats are good) inside the crate to keep the pup happy & busy until they get bored and take a nap. That's worked well for us. It's great that her foster mom is being so patient.

Good luck and let us know how it goes.
