Dog Urine Oder Masker/Dog repellent?

I like a carpet cleaner called Folex. It is easily found & inexpensive. I got mine at Home Depot for about $5,6 for a large bottle. It works on a variety of stains - old & new ones. You need to do crate training or confine. It will take a couple of months before pup will be able to hold it all night - their bladders are tiny. Not the easiest projects to do & why I only adopt older pups or adults.
