Hi,
We tried everything to get our dog to go in one spot. I hate having the kids run around the yard and not knowing where the 'logs' might be....we finally ended up buying one of those big screws that go into the ground and attaching a chain to it. When the dog tells us she needs to go out we put her on the chain and she goes in one spot...when she is done we take her off so she can run and play. Hope this helps.
