I had my very first dog in an apartment - 4th floor - no balcony, no elevator! Right downtown.
Some people thought I was mean having a dog in a two bedroom apartment ... my thoughts? If I can "fit" in the apartment, and I'm bigger than my dog, than the dog can fit.
If you're going to make sure you really exercise your dog, then why not? Most people I see in the burbs with dogs and a yard never walk / exercise or train their dogs.
At least in an apartment you HAVE to go out ... for me it was a motivator to exercise!
