Pomeranian or Shih Tzu?
The Shih Tzu is the calmer, more laid-back choice: an affectionate, lower-energy companion with a long coat that needs frequent grooming. The Pomeranian is smaller, bolder and more alert, with a fluffy double coat. Choose the Shih Tzu for a relaxed lapdog, and the Pomeranian for a spirited little watchdog with a showpiece coat.

- Grooming: high, daily brushing or a short cut
- Temperament: laid-back, affectionate
- Energy: lower, a relaxed companion
- Height: about 20 to 28 cm
Size and build
The Shih Tzu is the more solid dog. It is commonly cited at around 4 to 7.25 kg and stands roughly 20 to 28 cm at the shoulder, with a stocky, sturdy frame. A standard Pomeranian weighs about 1.9 to 3.5 kg at around 18 to 24 cm, so it is the lighter, more delicate toy of the two even though their heights overlap.
Both are comfortable in a flat and neither needs much space. If you want a small dog with a bit more substance to pick up and cuddle, the Shih Tzu has it. If you want a true lightweight toy breed, the Pom fits. Our size guide explains the standard Pomeranian range and why we never place undersized "teacup" dogs.

- Pomeranian: lightweight toy breed

Coat, grooming and shedding
Both breeds ask for regular coat work. The Shih Tzu has a long, dense coat that grows continuously and mats without attention, so owners either brush it daily or keep it in a short puppy cut to cut the workload. When it is well maintained, the Shih Tzu is often described as a relatively low-shedding breed.
The Pomeranian has a stand-off double coat that sheds steadily and blows out heavily once or twice a year, so it sheds more than a maintained Shih Tzu. It needs brushing several times a week and, crucially, should never be shaved to the skin, because the double coat may not grow back correctly. A teddy or "boo" trim is a tidy-up, not a shave. See how a double coat sheds for the routine. In short, the Shih Tzu sheds a little less, the Pom is fluffier and never gets clipped down.
Temperament, energy and barking
This is the biggest difference between the breeds. The Shih Tzu was bred to be a companion and little else, so it is typically laid-back, affectionate and lower energy, happy to potter about and settle on the sofa. It is generally the quieter of the two.
The Pomeranian is livelier, bolder and more alert. It is a spirited little watchdog that stays curious about everything and will sound the alarm at the door, so it is more vocal and benefits from more mental stimulation and early bark training. Read the honest barking guide and how a Pomeranian behaves at home to see what that means day to day. If you specifically want a calm, quiet, low-energy lapdog, the Shih Tzu is the more natural fit.
Temperament notes
- Shih Tzu: laid-back, affectionate, lower energy
- Shih Tzu: generally the quieter breed
- Pomeranian: lively, bold and curious
- Pomeranian: alert watchdog, more vocal
- Pomeranian: needs early bark training
Heat, exercise and HDB fit
Both breeds are happy with short daily walks and indoor play, and both suit flat living. A word on heat: the Shih Tzu is a flat-faced breed and can be more sensitive to heat and exertion, so it needs careful management in Singapore’s climate. The Pomeranian carries a thick arctic-origin coat and also feels the heat, so whichever you choose, walk in the cooler early morning and evening and keep them out of the midday sun.
On HDB, the Pomeranian is a clean yes: it is named on HDB’s approved small-breed list, as our guide to whether HDB allows the breed explains. The Shih Tzu is a popular small breed commonly kept in flats and is generally approved too, but confirm it on the current HDB list before you decide. Either way, one approved dog per flat and an annual AVS licence apply.
Flat living
- Both: short daily walks, flat-friendly
- Shih Tzu: flat-faced, watch heat and exertion
- Pomeranian: thick coat, also feels the heat
- Pomeranian: named on the HDB approved list
- Shih Tzu: confirm on the current HDB list
Which one is right for you?
Choose a Shih Tzu if you want a calm, affectionate, lower-energy companion for a relaxed household, and you are happy to keep up with the coat, either by daily brushing or a regular short trim. It is a gentle, easygoing dog, and if that is what you want, we would rather steer you there than sell you a busier breed.
Choose a Pomeranian if you want a spirited, alert small dog with a fluffy showpiece coat and plenty of personality, and you will invest in coat care and bark training. If that sounds right, see the Pomeranian puppies at our shop or line the Pom up against the other small breeds. We are Pomeranian specialists and place Poms only.

The flat face in a tropical climate
Brachycephalic means short-skulled, and in the Shih Tzu it produces the flat, wide face the breed is loved for. The cost is airflow. A shortened muzzle compresses the same soft tissue into less space, so the airway is narrower along its whole length. In cool countries that mostly shows up as snoring. In Singapore it shows up on the walk.
Dogs cool themselves by panting, which means moving air across wet tissue, and a restricted airway makes panting less efficient exactly when the dog needs it most. At 31 degrees and 80% humidity, a Shih Tzu reaches its limit sooner than a Pomeranian does, which is the opposite of what most people assume when they compare a fluffy dog to a flatter-coated one. It does not make the Shih Tzu a poor choice here. It makes early-morning and after-dusk walking non-negotiable, and it makes midday outings genuinely risky rather than merely uncomfortable. The same routine helps both breeds, and keeping a dog cool in Singapore sets it out.
Heat, honestly
- Panting is the only real cooling system
- A short muzzle makes panting less efficient
- Shih Tzu reaches its limit sooner outdoors
- A maintained double coat insulates both ways
- Both: walk before 8am or after 8pm
- Neither: never in a parked car
Health, side by side
Luxating patella, tracheal collapse and dental crowding appear in both breeds, as they do across most small dogs, and both benefit from a harness, a lean body weight and regular tooth brushing.
Beyond the shared list, the Shih Tzu's commonly cited risks cluster around the face: prominent eyes are more exposed to corneal ulcers and, rarely, proptosis, and dry eye is frequently mentioned, alongside the airway limitation above. The Pomeranian's own is alopecia X, which affects the coat and not the dog's health. If you are choosing between the two on health grounds alone, the honest framing is that the Shih Tzu's issues are more likely to need veterinary intervention and the Pomeranian's is more likely to just upset you.
Breed-specific watch list
- Shared: patella, trachea, dental
- Shih Tzu: corneal ulcers, dry eye
- Shih Tzu: restricted airway
- Shih Tzu: skin folds need daily cleaning
- Pomeranian: alopecia X, coat only
- Both: long-lived with routine care
Frequently asked questions
Pomeranian or Shih Tzu, which is bigger?
The Shih Tzu is the bigger, sturdier dog. It is commonly cited at around 4 to 7.25 kg, while a standard Pomeranian weighs about 1.9 to 3.5 kg. They stand at a similar height, roughly 20 to 28 cm for the Shih Tzu and 18 to 24 cm for the Pom, but the Shih Tzu is heavier and more solidly built.
Which is calmer, a Pomeranian or a Shih Tzu?
The Shih Tzu is generally the calmer, lower-energy breed. It was bred purely as a companion and tends to be laid-back and affectionate. The Pomeranian is livelier, more alert and more curious, so it usually wants a bit more mental stimulation and is quicker to react to what is going on around it.
Which barks more, a Pomeranian or a Shih Tzu?
The Pomeranian is more vocal by nature. It is an alert little watchdog that sounds off at doorbells and corridor noise, so it needs early bark training in a shared block. The Shih Tzu is usually quieter and more placid, although any dog will bark without enough company and stimulation.
Which needs more grooming, a Pomeranian or a Shih Tzu?
Both are real grooming commitments. The Shih Tzu has a long coat that needs daily brushing, or it is often kept in a short puppy cut to reduce the work. The Pomeranian needs brushing several times a week, blows its coat seasonally, and should never be shaved down to the skin.
Which suits a relaxed household better?
If you want a calm, cuddly, lower-energy companion, the Shih Tzu leans that way and is a lovely choice for a quieter home. The Pomeranian suits an owner who enjoys a spirited, alert dog with more personality and does not mind bark training and regular coat care.
