It seems likely that my cats would be able to get used to a puppy more easily than an adult dog, seeing a little puppy I dont think they would look on that as being a threat as they might if it's an adult corgi. On the other hand, if I find an adult that is laid back and is used to cats, they could very easily learn to get along. Personally I'd prefer raising a puppy myself, even if it means all the training and puppy issues.

Actualy, I think I would enjoy it! As for temperment, more of a laid back but eager for a walk corgi would be perfect. But really, I'll be happy with any Corgi!
Thanks for the welcome!
