Does the Sims team understand how dog walking works?

I'm pretty sure they based the dog walking on the jogging routes that they build into the game and no one told them that walking a dog is slower than jogging which is why jogging with the dog is the only one that seems to make sense.

On a side note, why are they not using their umbrella when they are walking the dog in the rain? How they could look at that and think "That will do" amazes me.
