Hey there, it’s Sterling!
So you bought the Doggy Bathroom, but your dog won’t go near it. It’s true it’s not the best to force them to go in, so you’re going to have to try a sneakier way. It’s also not good to tempt them by placing treats inside as there needs to be a clear physical distinction between their eating space and potty space. Only give them treats after they have entered or used it!
First, try placing their used pee pad under a new one near the Doggy Bathroom, and move it closer and closer until they are inside. The scent of the used pee pads will attract them. Bring their attention to the fact that their pee pad is there frequently, so they remember. Start with a lightly used pee pad, but if it's not enough, use one that's heavily soiled with pee. If it's still not enough, you can go as far as asking a dog-friend for one of their used pee pads. I know it sounds strange, but the best way to get a dog to leave their mark is over another dog's.
For dogs who squat instead of leg lift, try removing the enclosure from the base and repeating the above with only the base. This can eliminate some of the initial fear they have.
Patience is crucial, and all dogs are different. Some take to it right away, while others can take up to a week, or more. It requires work from both you and your pup. Once they get it, make sure to give them lots of treats!
