The context
35°C on a Ho Chi Minh City afternoon is a death zone for a flat-faced dog
Vietnam's climate is hard on pets in particular ways: harsh dry-season sun, heavy wet-season humidity, and air quality that swings sharply in Ho Chi Minh City and Hanoi. Brachycephalic breeds — Pugs, French Bulldogs, Persians — can suffer heatstroke after fifteen minutes in 33°C sun.
The trouble is that while you are at the office you cannot see what your pet is facing at home. By the time you get a free moment to check the weather, it can already be too late.
The answer
A sentinel running 24/7 — a push notification exactly when it matters
-
Real data sources
VowVet reads temperature, humidity and AQI from Open-Meteo (WMO standard) and IQAir (PM2.5), refreshed every thirty minutes per district.
-
Tuned to your pet
Alerts key off species, breed, age and body condition. A four-year-old Pug at BCS 7 triggers at 31°C. The Husky in the same house triggers at 28°C.
-
Push that genuinely arrives in time
Web Push through the service worker reaches you within sixty seconds — no need to open the app, no need for the phone to be awake.
Five kinds of alert
Every alert names the action, not just the number
-
🔥 Heatstroke risk building
Temperature past your breed's threshold. Do this: close the windows, set air conditioning to 26-28°C, no walks until 6pm.
-
💧 Dry air, dehydration risk
Humidity below 40% with temperature above 30°C. Do this: refill water four times a day, add one wet meal.
-
🌫️ AQI dangerous for lungs
PM2.5 above 100 µg/m³. Do this: keep them indoors, skip the walk, run an air filter where they sleep.
-
🌧️ Storms and falling pressure
Heavy rain plus a pressure drop — a thunder-shy pet needs a quiet space prepared in advance.
-
❄️ Cold night air in the highlands
For Da Lat and similar: below 18°C alerts owners of short-coated Vietnamese breeds — add a blanket, move them off a cold floor.
Ready for the festivals
Tet, Christmas, Vu Lan — it is not only about weather
VowVet's festival detector reads both the lunar and solar calendars. Three days before Tet it warns you: fireworks and heavy traffic raise the odds of both a lost pet and noise trauma. It suggests the preparation — check the QR passport is still legible, set up a safe crate, and have mild sedation ready only if your vet has prescribed it.
