Airway
A shortened muzzle moves less air, so the heat that panting sheds leaves the body more slowly than it arrives.

The mechanism
Why heat reaches a Shih Tzu first
Coat
A dense coat holds heat against the skin, so cooling lags well behind what the weather looks like.
Where that comes from
No published HRI odds located. Brachycephalic plus a long dense coat. PROVISIONAL.
What the number is not
The odds are for whether a dog of that breed ever presented with heat-related illness. They set the RANKING; they are not a multiplier on how long a dog may be outside, and the app never uses them as one.
Tell any vet before sedation
Tell any vet, and any groomer who uses sedation, that [name] is flat-faced before he goes under for anything, a dental included. The risky part of anaesthesia for flat faces is not going to sleep but waking up: in a study of 223 flat-faced dogs, complications after the anaesthetic were about four times as likely as in matched dogs, mostly once the breathing tube came out. Ask the practice to keep the tube in until he is properly awake and to have someone watch him right through recovery.
Water safety
Can a Shih Tzu swim?
Poor swimmer
Free forever in the app. The swimming verdict and the cool-down protocol are the two pieces of content that exist to prevent a drowning and a death, and neither is ever behind a paywall.
Flat face plus a long coat that soaks up water and drags him down. Fine for shallow paddling in a vest, not for pools or open water.
What to own
The gear that earns its place
Before anything else
Y-harness only, and never scruff him or jerk his collar.
It keeps pressure off a short airway and off eyes that already run dry and ulcer-prone, and with sockets this shallow a collar yank or a scruff can help displace an eye entirely.
Y-shaped harness, never a neck collar
Keeps pressure off a short airway and off eyes that already run dry and ulcer-prone.
Cooling mat
A cool surface under a coated dog does more than a fan alone.
Grooming kit and a good groomer
A matted coat traps heat and moisture against the skin. A tidy summer trim is fine, but not shaved to bare skin, which risks sunburn.
Dog life jacket with a grab handle
A wet coat gets heavy quickly, and the flat face makes keeping his nose clear hard work.
Portable water bottle with trickle bowl
Lets you give little and often on a walk instead of one desperate gulp at the end.
Every day
The daily jobs a Shih Tzu actually needs
Not a generic list. These are the tasks this breed’s anatomy earns — the same set the app seeds a new profile with — and each one carries the guidance it comes from.
Brush teethdaily
Daily brushing removes plaque before it hardens into tartar, the main preventable cause of dental disease.
American Veterinary Dental College (AVDC): daily tooth brushing is the standard recommendation.
Check and clean earsweekly
Wax and moisture build up in ears and can lead to infection, especially in floppy or hairy-eared dogs.
Veterinary guidance. Frequency ranges from weekly to as directed by your vet. · cadence is a range, not a clinical number
Trim nailsevery 3–4 weeks
Overgrown nails change how a dog stands and walks and can strain joints over time.
General veterinary guidance. Cadence depends on how much the nails wear down naturally. · cadence is a range, not a clinical number
Nose balm (if dry)as needed
A dry or crusted nose can be soothed with a dog-safe balm, but many dogs need nothing.
PROVISIONAL: no clinical frequency is established. Apply only if the nose is visibly dry. · cadence is a range, not a clinical number
Clean facial foldsdaily
Facial folds trap moisture and debris, which breeds the fold dermatitis this breed’s kind of face is prone to.
Veterinary dermatology guidance for fold (intertrigo) dermatitis. Cadence is a range: more often in hot, humid weather. · cadence is a range, not a clinical number
Brush coat2–3×/week
Brushing removes shed undercoat and prevents mats, so this breed’s thick coat does not trap heat against the skin.
General grooming guidance; no single clinical cadence. More often during heavy shedding. · cadence is a range, not a clinical number
Bowls and meals
Water, food, and the gap between them
Water
Little and often after walks and during heavy panting. Fast gulping brings up swallowed air and food. Wipe his beard afterwards too, as a permanently damp face gets sore.
Bowls
He gulps less than a Pug or Frenchie but still swallows air. A shallow slow feeder helps, and a slow-drink bowl keeps that long face and beard drier.
Food and effort
Less prone to bringing food back than the very flattest faces, but the shortened muzzle still puts him in that group. A settled stomach before anything energetic is worth the wait.
Beyond the heat
What else to watch
Eyes — proptosis
Emergency signs: An eye that suddenly bulges or sits forward of its lids is an emergency. Keep it moist with saline or plain water on a clean cloth and go now: Shih Tzus were the second most common breed in the biggest recent study of displaced eyes.
Avoid: Never scruff him, never jerk the collar, and supervise rough play with bigger dogs. In that same study most displaced eyes followed a dog fight or a bite, so play with a much larger dog is its own risk, however friendly.
Spine
Shih Tzus are one of the long-backed, short-legged builds that disc disease favours. Sudden yelping, wobbliness or dragging back legs is an emergency.
Prevention: Ramps or steps for the sofa and bed instead of repeated launches, and keep him lean. This is list-level clinical guidance for his body type rather than a Shih Tzu study.
Particular to this breed
Risks a Shih Tzu carries that most dogs do not
Eye ulcers and dry eye
Shih Tzus have poor tear-film quality and blink incompletely, so the eye surface damages easily. Squinting or discharge means a vet the same day.
Coat and skin in heat
Matting stops air reaching the skin and holds damp. Regular brushing is genuine heat safety, not just tidiness.
Dental disease
UK vet records show gum disease as his most common diagnosis, from a lot of teeth in a small jaw.
If they overheat
Cool first. Call while you cool.
The cool-down for a Shih Tzu
Cool first, then go. Pour cool (not icy) water over him, work it right through the coat to the skin, keep air moving, and drive in with the AC on. Never leave a wet towel on him. Dry him properly afterwards, nose fold included.
Stop, whatever the number says
Heavy or frantic panting, lagging behind or wanting to stop, unsteadiness, or gums that look dark, grey or brick red. Get out of the heat and start cooling immediately.
The whole emergency screen is free forever and works with no signal — the steps, your own vet’s number, and the nearest 24-hour hospital, all held on the phone.
