Shih Tzu exercise needs: how much, what kind, by age

Shih Tzus are brachycephalic companion toys with a distinctive flat face, prominent eyes, and long flowing coat. Daily exercise needs are modest but real. Extra weight compounds breathing and joint stress. The trick is finding the right pace, the right time of day, and the right intensity for a dog whose anatomy works against sustained exertion.

Daily exercise guide

Age Total daily Intensity
Puppy (to about 10 months) Short play, short walks and training; rest when tired; no long walks, hikes or runs until fully grown Very low
Adult Up to 1 hour a day Low
Senior (from about 9.5 years) Less than in the adult years: regular, gentle, little and often Very low

The adult figure is the exercise band The Kennel Club gives for the breed. There is no sourced minutes figure for puppies or seniors: PDSA says there is no scientific evidence behind the “5 minutes per month of age” rule, and advises play, short walks and training for puppies and regular, gentle, little and often exercise for senior dogs. Senior age follows the AAHA 2019 Canine Life Stage Guidelines (the last 25% of estimated lifespan), counted from the breed’s median life expectancy in McMillan et al. 2024 (Scientific Reports). AAHA’s 2021 nutrition guidelines put skeletal maturity at around 12 months for small and medium dogs and closer to 15 to 16 months for some large and giant breeds, and your vet confirms when your dog has finished growing. Your vet can set the amount for your dog.

Two short walks beat one long one. Split exercise into short sessions so breathing has time to recover between bouts.

What makes Shih Tzu exercise different

Brachycephaly changes everything. Shih Tzus have shortened airways, narrowed nostrils, and elongated soft palates. The University of Cambridge BOAS Research Group lists the Shih Tzu among brachycephalic breeds. The practical implication: watch breathing during any exertion. Loud snoring, gagging, blue or pale gums, or collapse during exercise = stop, cool the dog, and call your vet. Your vet can advise on treatment, which can include surgery.

Heat intolerance is severe. Short-nosed dogs do not breathe as efficiently and can have difficulty cooling off when playing or exercising (AVMA). PDSA lists flat-faced dogs among those most at risk of heatstroke. There is no sourced temperature cut-off: the RVC advises restricting exercise on warm days and walking early in the morning or later in the evening. Plan walks for dawn (best) or after sunset.

Eye prominence = trauma risk. PDSA says flat-faced breeds have very shallow eye sockets, so their eyes bulge slightly and are more likely to get infections and injuries. Tall grass, rough play, and brush at face height can injure the eye. Walk on cleared paths and avoid off-leash with face-level vegetation. Eye discharge changes (color, amount, one eye vs both) warrant a vet check.

Long flowing coat = post-walk grooming. Picks up burrs, mud, and debris. Daily brushing prevents painful matting. Many owners keep pet Shih Tzus in a short “puppy cut”: easier to maintain.

Spinal sensitivity. PDSA lists intervertebral disc disease among the conditions Shih Tzus may develop. Keep your dog lean and keep up daily exercise. No study has shown that banning jumps or adding ramps prevents disc disease. After a disc episode or surgery, follow your vet’s activity limits. Sudden back pain, wobbling or dragging legs: call your vet now.

Food motivation is high. Mental work and trick training are easy wins. A short game of “find the treat” or shaping a new trick can stand in for part of a walk on bad-weather days.

Best activities

  • Slow sniff walks during cool hours (dawn or after sunset).
  • Indoor fetch with soft toys.
  • Trick training and shaping (food-motivated).
  • AKC Trick Dog and Rally Obedience titles.
  • Short, flat-trail outings (with water and shade breaks).
  • Therapy-dog work (temperament suits).

Activities to avoid

  • Walks in the heat of the day.
  • Sustained running or fetch sessions.
  • Off-leash where face-level vegetation grows.
  • Dog parks during chaotic hours (eye trauma + heat risk).
  • Air travel in cargo without talking to your vet first (the AVMA reports short-nosed breeds are more likely to die on airplanes than dogs with normal-length muzzles; check the airline’s policy).

Sample weekly schedule

  • Mon to Fri: cool-time morning walk + indoor play / trick session + cool-time evening walk
  • Saturday: morning walk + grooming session + indoor obstacle course
  • Sunday: dawn walk in a new (shaded) park + lazy afternoon
  • Hot days: indoors with AC + mental enrichment

Owner mistakes to avoid

  • Walking in summer heat. Heatstroke can rapidly become a life-threatening emergency (RVC).
  • Ignoring snoring as cute. Loud snoring = airway obstruction signal. Discuss with vet at next visit.
  • Letting weight creep. Each extra pound stresses an already compromised airway.
  • Long sessions instead of split. Split the daily total into short sessions. Recovery time matters more than total volume.
  • Pulling hard on a collar leash. Switch to a harness: Cornell advises one instead of a neck collar for brachycephalic dogs.

What to keep an eye on

  • Exercise minutes (per session, not just total).
  • Breathing recovery time after walks.
  • Snoring loudness or new gagging.
  • Weight monthly.
  • Eye discharge (color and quantity).
  • Coat condition and grooming events.

FAQ

Indoor only: is that okay?

Some indoor exercise works on extreme-weather days, but daily cool-time walks add bladder, joint, and behavioral benefits a flat doesn’t replicate.

How hot is too hot?

There is no sourced temperature cut-off. The RVC advises restricting exercise on warm days, walking early in the morning or later in the evening, and checking pavements with your hand. The American College of Veterinary Surgeons notes that heat and humidity both bring on breathing trouble in brachycephalic dogs. When in doubt, stay in.

Trick training?

Excellent fit. Shih Tzus are food-motivated, social, and enjoy learning. Short sessions build a deep skill set without taxing the airway.

My Shih Tzu snores loudly. Is that normal?

Some snoring is breed-typical. Loud snoring, gagging, or labored breathing during sleep is worth a vet visit: noisy breathing is a listed sign of brachycephalic syndrome (American College of Veterinary Surgeons).

Harness or collar?

Harness, especially for any pulling. Cornell advises a harness instead of a neck collar for brachycephalic dogs.

Should I get BOAS-graded?

If your Shih Tzu snores loudly, gags, or struggles in heat: yes. Ask your vet about a BOAS assessment; the University of Cambridge BOAS Research Group publishes guidance on recognition and diagnosis.
