I should clarify. My guess is that most people's idea of a city walk is less than 30 minutes - once or twice around the block. For a young, active and athletic dog that would be insufficient and result in a bored dog which is a destructive dog. However, if each of these "walks" is a 45 - 60 minute romp, then you may be okay. As you point out, larger breeds - especially molossers - need less exercise and generally are easy keepers. Given the choice between a Bull Mastiff and a JRT in a city apartment, I would choose the BM. And two 45 minute outings - one a walk, the other an easy run. Plus another bathroom break before bed.
Most dog behavioral "problems" can be solved with exercise and relieving boredom.
