Some dogs really can handle modest exercise. I know a happy cocker spaniel who’s an apartment dweller. Gets a lot of human interaction with almost constant human companions, with about ten humans rotating in and out of the dogs life over a month. So, exercise wise, not too much except walks in the city and parks, but socially a very interesting life. I am sure a husky would go insane in the same circumstances. It also very much depends on the individual, so if you get a dog, find out as much as possible how it’s close relatives behave.
