With a "toy" breed, that's easy. With some 80-100 pound dog, good luck with that. I don't know many people capable of lifting that much weight easily, certainly not all the single women in this area that have big dogs.

That seems fair? They might have cars then. It seems you're imaging a scenario of a specific single woman with slight muscle mass with her 100lb dog and no car living in the heart of DC. I'm sure there are a few but I doubt that's the norm.
