We have actually had our puppy potty for two years when we moved to another house where the yard was fully paved around garden areas. Our 15 y.o. Kelpie, Kate, was happy once she had been introduced to the puppy potty. Unfortunately, Kate passed away about a year later, and we missed her so much, that we decided to get another canine companion. Being in our 70s, we had no intention of getting a puppy, but after exploring the interstate options, we did go down that road, and it was so easy to place the potty in a position where when our pup went out through the doggy door, he almost fell over the potty, and so our job was done. He knew what the little island of green grass was for, and one often slowly-learned lesson was easily accomplished with the help of our puppy potty!!
