Understanding your Shih Tzu’s behavior

Dogs 2 min read Updated on October 6, 2026

In shortThe Shih Tzu was made for one thing: keeping company. He does it well, with quiet stubbornness and a flat face that complicates reading. In him, breath and gaze speak of anatomy first.

What defines them

A Tibetan then Chinese palace dog, the Shih Tzu is affectionate, confident, friendly with almost everyone and not very interested in obedience. His short muzzle limits his breathing and heat tolerance, his large exposed eyes get injured easily, and his coat needs daily care. He is known for slow house-training, often from lack of consistency more than ability.

What matters when you read them

  • He pants in a warm room after play: anatomy first. Cool him before interpreting.
  • He “sulks” at a cue and turns his head away: breed stubbornness, and sometimes a calming signal if you raised your voice.
  • He pees indoors despite walks: review the routine and the length of outings before talking about character.
  • He rubs his eyes, blinks on one side: a gentle emergency. His prominent eyes get damaged fast.

Three things that help

Coolness. No midday sidewalk, no car in the sun. Short games, water available.

A strict potty routine. Outings at fixed times, immediate reward outside, no punishment inside. He learns, but slowly.

Grooming as a ritual. Daily brushing, eye corners cleaned, hair kept out of the eyes. A matted Shih Tzu gets irritable.

Young, adult, senior

As a puppy, house-training can take six months or more: patience and regularity. As an adult, watch weight, eyes, crowded teeth in a small jaw and breathing. As a senior, kidneys, back and eyes dominate. A Shih Tzu who bumps into things or hesitates in the dark may be losing his sight.

Frequently asked questions

My Shih Tzu is not getting house-trained. Is he doing it on purpose?

No. The breed is known to be slow, and most failures come from an irregular routine or punishments that teach him to hide to go. Fixed outings, reward outside, enzymatic cleaning inside, and time.

He snores very loudly. Is that normal?

Common in short muzzles, but not harmless. If he snores while awake, chokes while eating or tires quickly, have his airways assessed.

He is stubborn. How do I get him to obey?

With rewards, very short sessions and no restraint. The Shih Tzu was not bred to work; he cooperates when it pays. Pressure makes him shut down.
