Every winter, Lahore disappears under a grey blanket of smog. On some days the city has ranked as the most polluted in the world. On 20 November 2025, for example, Lahore’s AQI hit 386 at 8 am (Dawn). We talk a lot about masks and air purifiers for people, but our dogs, cats and birds breathe the same toxic air, closer to the ground and without any mask. This guide from the vets at Round Lake Animal Hospital explains how to protect pets from smog, which warning signs to watch for, and when your pet needs a vet.
Quick answer: To protect pets from smog in Lahore, walk them in the early afternoon when the AQI is usually lower, keep walks short, keep windows closed during the worst hours, run a HEPA air purifier at home, wipe their paws and face after every walk, and see a vet if they start coughing, wheezing or breathing fast.
How Smog Affects Your Pet’s Health
Smog is a mix of fine dust, smoke, vehicle exhaust and gases. The most dangerous part is PM2.5, particles so small they travel deep into the lungs. In pets, these particles irritate the eyes, nose, throat and airways and trigger inflammation. That inflammation can lead to coughing, sneezing, watery eyes and breathing trouble, and it can make existing heart and lung problems worse.
Animals are not immune. During Lahore’s smog season, animals at Lahore Zoo have shown eye irritation and breathing difficulties, according to wildlife officials quoted by Dawn. Your pet at home faces the same air, just on a smaller scale.
Which Pets Are Most at Risk from Smog?
Every pet can be affected, but some need extra care during the smog season. Knowing which pets are most vulnerable helps you protect pets from smog where it matters most:
- Flat-faced (brachycephalic) breeds such as Persian cats, Pugs, Shih Tzus and Bulldogs, which already have narrow airways.
- Pet birds such as parrots, cockatiels, budgies and finches. Their respiratory system is extremely efficient, which also means they absorb airborne toxins quickly.
- Senior pets, puppies and kittens, whose immune systems are weaker.
- Cats with asthma and pets with existing heart, lung or allergy problems.
- Outdoor and guard dogs that spend nights in the open or on rooftops.
Warning Signs Smog Is Making Your Pet Sick
Watch your pet closely on high-smog days. Common signs include:
- Coughing, gagging or a honking cough
- Sneezing and runny nose
- Red, watery or itchy eyes, or frequent pawing at the face
- Wheezing or noisy breathing
- Faster breathing than normal while resting
- Tiredness, low energy and reduced appetite
- In birds: tail bobbing, fluffed-up feathers, or breathing with an open beak
Emergency signs, go to a vet immediately: open-mouth breathing in a cat, struggling to breathe, blue or grey gums or tongue, collapse, or a bird sitting at the bottom of its cage. These signs need urgent care. Our animal ambulance service can help if you can’t transport your pet safely.
How to Protect Pets from Smog: 10 Vet-Approved Tips
1. Check the AQI and walk at the right time
Check the AQI on your phone before every walk. In Lahore, smog is usually worst at night and in the early morning, when cold, still air traps pollution near the ground, and it tends to ease by the afternoon. On 20 November 2025, for example, the AQI dropped from 386 at 8 am to 193 by 2 pm. Early afternoon is usually the safest time for walks.
2. Keep walks short and skip hard exercise
Running and fetch make pets breathe faster and deeper, so they pull in more polluted air. On bad days, take short toilet walks and move playtime indoors with tug toys, puzzle feeders, sniffing games and simple training sessions.
3. Protect pets from smog indoors
Your home should be your pet’s safe zone. Keep doors and windows closed during peak smog hours. If you can, run a HEPA air purifier in the room where your pet sleeps and spends the most time.
4. Wipe paws, face and coat after every walk
Soot and dust settle on your pet’s fur and paws, and they lick it off later. Wipe the paws, face and coat with a damp cloth after outdoor time. Regular professional grooming also helps keep the coat clean during the smog months.
5. Keep your pet well hydrated
Fresh, clean water keeps the airways moist and helps the body clear irritants. Change the water bowl often, because dust settles on standing water.
6. Avoid indoor smoke and fumes
Indoor air can be just as harmful. Avoid smoking indoors, agarbatti and incense, scented candles, aerosol sprays, mosquito coils, and coal or wood heaters (angeethi) in rooms where pets stay.
7. Give pet birds extra protection
Move cages indoors and away from windows and the kitchen. Fumes from overheated non-stick pans can be fatal to birds. A small air purifier near the cage helps a lot. For bird health checks, visit our Avian Care Center, and read our guide to keeping exotic birds healthy.
8. Bring outdoor dogs inside at night
Guard dogs and pets kept on rooftops or lawns are exposed all night, when smog is heaviest. Bring them indoors, or give them a covered, sheltered kennel, until the air improves.
9. Keep vaccinations up to date
When airways are already irritated by smog, infections such as kennel cough, canine distemper and cat flu can hit harder. Make sure your pet’s vaccination and deworming are up to date before the smog peaks.
10. Book a check-up for high-risk pets
If your pet is old, flat-faced, asthmatic or has a heart condition, see a vet early in the season. Ask about a smog care plan, including whether your pet needs any supportive medication or diet changes.
How to Protect Different Pets from Smog: Dogs, Cats and Birds
| Pet | Main smog risk | Most important tip |
|---|---|---|
| Dogs | Long outdoor walks and night-time exposure | Short walks in the early afternoon; wipe paws and face afterwards |
| Cats | Asthma attacks, especially in flat-faced breeds | Keep indoors; watch for open-mouth breathing |
| Birds | Very sensitive lungs that absorb toxins quickly | Cage indoors, away from windows, kitchen fumes and smoke |
| Rabbits and small pets | Dust and ammonia build-up in closed rooms | Clean bedding often; use an air purifier |
When to See a Vet in Lahore
Even when you do everything right to protect pets from smog, some pets still react. Mild sneezing that clears up in a day may be nothing to worry about. Book a visit if your pet has a cough lasting more than a day or two, discharge from the eyes or nose, reduced appetite or unusual tiredness. Smog irritation can also open the door to respiratory infections and flare up allergies, which need proper treatment.
At Round Lake Animal Hospital, our vets can examine your pet’s lungs and airways, run chest X-rays and laboratory tests to find the cause, and provide hospitalisation when a pet needs close monitoring. For cats, also read our guide to the warning signs that need an emergency vet.
Frequently Asked Questions
Can smog make my dog or cat sick?
Yes. Smog particles irritate the eyes and airways and can cause coughing, sneezing, wheezing and breathing difficulty. Pets with asthma, heart disease or flat faces are affected most.
Is it safe to walk my dog during smog in Lahore?
Short walks are fine for most healthy dogs, but avoid early mornings and late evenings when the AQI is usually highest. Choose the early afternoon and skip running or long play sessions outdoors.
Do air purifiers help protect pets from smog?
Yes. A HEPA air purifier is one of the simplest ways to protect pets from smog at home, because it lowers fine particles indoors. Place it in the room where your pet spends the most time and keep windows closed during peak smog hours.
Should my dog wear a mask in smog?
Masks for pets are generally not recommended. Most pets don’t tolerate them, and a poorly fitted mask can make breathing harder. Limiting outdoor time and cleaning the air at home work better.
Are pet birds more sensitive to smog?
Yes. Birds absorb airborne toxins very efficiently, so smog, smoke and kitchen fumes affect them faster than other pets. Keep cages indoors, away from windows and the kitchen, and see a vet quickly if your bird breathes with its beak open.
