According to Dr. Timothy Mann, a New York City veterinarian, dogs, energy levels and temperament are more important than factors and size. Some large dogs don’t need a big living space if you provide other opportunities for exercise.  He says that St. Bernards and even great  Danes can all live comfortably in the city. The need regular long walks or a run in a dog park. Then, when they come home, they will be content just lying around. Greyhounds will surprise you. They like to run when they have a chance but they are big couch potatoes! Just give them enough exercise outside and they’ll do fine.

There are advantages to having smalls breeds in apartments or condominiums. Some small dogs can even be trained to use a litter box or fake grass on a balcony so you don’t have to worry about rushing downstairs or waiting for the elevator. Apartments are usually too small to accomodate a dog exercise pen, so it’s important that you take your little one out often for exercise.
