Recently, I spoke with Ruby Richards, a representative at a Durham animal shelter, about pets and small spaces. First off, Ms. Richards believes that smaller breeds of dogs (such as a chihuahua) are more ideal, since they take up less space. However, even these dogs need the kind of care that pet owners in suburban houses might not think about as much.

Dogs, like this chihuahua, need to spend more time outside if they live in smaller spaces
First off, according to Ms. Richards, condo dogs need to be walked more often, as they do not have a backyard to run around in. If you work 12 hours a day, she suggests that other pets, such as a cat, would be preferrable (or get a dog walker). Also, in a house with a backyard, dogs can be trained to go to the bathroom in the backyard. This is not possible in an apartment. Doggie daycare is another option as it gives the dogs to exercise more often than they would if they stayed at home.
There are, of course, many ways to get a pet. Some will adopt from breeders, while others will get them at pet shops. Another option is to adopt a shelter dogs. These dogs are usually older (usually 2-6) and their personalities are already set. Prospective owners fill in an application form and are matched based on the information provided. According to Ms. Richards, sometimes, there are dogs who find new homes almost immediately after they’re dropped off at the shelter. However, there are also dogs who stay in the shelter for months (sometimes, they need to stay in shelters – pregnant dogs are never adopted out).
It is important that dogs are treated well. They are, after all, living beings, not accessories (doggie strollers shouldn’t be used unless the dog is disabled). Dogs need to socialize with other dogs and to excercise, so it’s important to take them out. It is also important to train them to be like dogs. Pet ownership is a privilege, after all, and not a right.

Some good points here but it is important to understand the characteristics of a breed you are considering. Not all small dogs make good apartment pets. For example a Jack Russell Terrier is a small dog but their energy level and tendency to bark means they’re not an ideal apartment dog for everyone. There are also medium and large breeds that do make good apartment pets. If your apartment is large enough to accommodate him even a Great Dane can be a good choice (their exercise needs are not high other than needing to be walked like any dog, and indoors they’re pretty mellow). These are just a couple of examples, the key thing is to do your research on a breed you’re considering, and don’t pick a dog based solely on size or looks.
Also, buying a dog from a pet store is a horrible idea. Pet shop puppies come almost entirely from puppy mills, not from responsible breeders. The most humane choice is to buy from a shelter or rescue group (many of which specialize in specific breeds if you have your heart set on certain breed), or from a responsible breeder.
@Sherry: Thanks for the info. Yes, Jack Russell terriers are not exactly the best choice for (small) apartments.
