Riley isn't registered and TJ is. Registration doesn't really matter to me. I almost didnt register TJ even though I had the papers. I decided to register him though because I am paying for a package to get his pedigree. I wanted to see who his grandparents were, etc. It sounded cool. Registration isn't important to me at all.
I would take an unregistered or a registered dog in a heartbeat. I love my dogs for who they are, not whether they have papers or not.
