Often topping the list of the most popular breeds in major American cities, Yorkies thrive in apartments and confined spaces, making them a go-to for urban living.

4. Pomeranian
The Pomeranian may be tiny, but this breed has a big, dramatic backstory. Named after Pomerania, a historic region in Germany, early Poms were nothing like today’s cloud-on-legs companions. Their ancestors weighed up to 30 pounds and lacked the iconic lion-like fluff.
And thus, the modern Pom was born: small, stylish, and absolutely convinced they’re the most important creature in the room. Pomeranians belong to the spitz family, dogs originally bred for colder, arctic climates.
That’s why they sport a luxurious double coat, sharp little pointy ears, almond-shaped eyes, and an alert, intelligent expression that says, “I noticed that.” They’re quick learners, endlessly curious, and surprisingly confident for dogs that weigh less than a house cat.
Despite their high energy level, Poms make excellent family dogs when properly socialized. They’re affectionate, playful, and love being involved in everything—expect them to supervise your daily activities like a tiny, fluffy manager.
That gorgeous coat does come with responsibilities. Pomeranians are heavy shedders, and their thick fur benefits from brushing several times a week to prevent tangles and keep them looking like the regal floof they are. Skip the grooming, and you may find Pom glitter (fur) on every surface of your home.

Shih Tzus are equally at home in small city apartments or on a country farm—they’re flexible like that. They adore younger as well as older children, get along well with other animals, and generally just want to be wherever their people are.
Exercise needs? Totally apartment-friendly. Shih Tzus are big fans of indoor play, short walks, and long lounging sessions. They’re not training for a marathon—and they’d prefer you weren’t either. This makes them ideal for people who want a dog that enjoys activity in moderation and relaxation in abundance.
Their silky coat is one of their standout features and does require regular grooming to keep it tangle-free and luxurious. Whether you keep it long and flowing or opt for a shorter, more manageable cut, a little coat care goes a long way with this breed.
