No, i wouldn't think so at all. A little foresight and modular design is not _that_ hard. Sure, after you implement the Dog Class you know better what the Pet Class may need, but you can most likely already have 75% of that Pet Class ready beforehand. If the OPs software design (for a particular subset!) is so complex he can't imagine it in his head: either the design is too complex or the programmer is not very good, imo. Any why the hell do we need the next acronym?!
