No worries if you posted this question before. It's easy to forget when/what is posted sometimes.
Just for information, our Riley is 18 weeks old and weighs 12 pounds! He is gonna be a big boy I guess. Sounds to me like Colby will probably end up within the 13-18 pound breed standard.
We originally wanted a smaller Cav, but we got Riley. He will most likely be quite past the breed standard, but it really doesn't matter to us. We love him the way he is.
Unless you will be showing Colby, it may not matter if he doesn't quite fall within the standard. But he probably will.
