It works!
Often things ordered from internet sites are complete junk, but I was desperate; tried air diffusers, various sprays, nothing was working and so why not try these. Before my youngest pup (a rescue with a bad experience prior) went in the den, kitchen, hall, living room, bedroom. I put the pad down, she went right to it and has had no accidents off the pad in over 3 weeks. Ordered more to rotate as they are being washed. They really DO work! It's made life and clean up super easy and the pup is just about trained completely.
