Thanks a bunch guys! I've never experienced this with a pup before, so I'm clueless. It's good to know he may grow out of it.

I'll try the advice given & suggest my guests do the same to see if that helps. I know it doesn't matter if he's just pottied or not, he'll do it either way (it's just a lot less 'sprinkling" if he's just pottied).
He hasn't been neutered yet as we prefer to wait until they are 6 months old. Hopefully he'll be out of that by then b/c we will have to nueter him since we have his sister in the house as well...don't wany any surprises!
