This being my first small dog (Malti-Poo) experience, adopting her as a stray, and not knowing if she was potty trained, I ordered a pack. She quickly used one, even though she IS potty trained, but only if I don't take her out when she needs to go. I was pleased with how quickly I got them. I've washed them a couple of times and they wash well. Very good product so I bought another pack and use one as a mat under her food and water bowls.
