Dog houses give us options, options on where to have an animal - particularly a large one in the case of small houses. I have a friend that lives in a small house & has a large (90+ pounds) German Shepherd. Navigation in said house is nigh to impossible unless the dog is outside. If so in RL, I suspect sim life would be similar. Dog house gives the option of where to put the dog. We have them in TS2, so what's his problem? Deciding on what goes into a game solely on personal bias is poor business practice. For a game that supposedly is about giving players options, there seems to be repeated effort to limit/remove them.
