I was going to register Lexi with some club (can't remember which one) but I decided that since I was not going to show her that I might as well save my money. I have heard a lot of bad things about the AKC. Personally I think unless you are showing your dog it is kind of a waste of money to register them.
the breeder gave me the certificate so I can register Bella with the NKC. It only cost me $8 to send the papers and I got a certificate back with her pedigree. I'm not breeding her or showing her so I guess it doesn't matter but it wasn't a lot of money so I just sent it.
