Air pollution is no longer just a human health concern. In cities like Delhi NCR and Mumbai, rising smog levels are increasingly affecting pets, triggering respiratory distress, skin sensitivities, and eye
irritation. Veterinarians are now seeing a clear seasonal pattern emerge, with cases spiking during periods of poor air quality.
“We notice an increase in cases of pets experiencing respiratory issues, irritation in their eyes, and skin allergies during peak smog levels in the Delhi NCR region,” says Dr. Abhishek Choudhary, Consultant Veterinarian, Vetic Pet Clinic. According to him, toxic gases and fine particulate matter present in polluted air can aggravate existing respiratory and cardiovascular conditions in pets, much like they do in humans.
Why Pets Are Especially Vulnerable
Pets, particularly dogs and cats, are closer to the ground where pollution levels are often higher. Their smaller airways, faster breathing rates, and prolonged exposure during walks make them more susceptible to airborne pollutants. Short-nosed breeds, senior pets, and animals with pre-existing heart or lung conditions are at even greater risk.
“Prolonged exposure to polluted air can worsen respiratory distress and lead to long-term health complications if ignored,” explains Dr Choudhary. Symptoms may start subtly, mild coughing or watery eyes but can escalate quickly if exposure continues.
Outdoor Precautions During Smog Season
One of the most effective steps pet parents can take is limiting outdoor exposure during high-pollution days. Dr. Choudhary advises reducing the duration of walks and timing them carefully. Early mornings or late evenings, when pollution levels tend to be marginally lower, are preferable.
Monitoring daily AQI levels has become essential. “Pet parents must track air quality on a day-to-day basis and avoid stepping out altogether during heavy smog,” he says. On severe days, indoor play, enrichment toys, and short bathroom breaks are safer alternatives to long walks.
Indoor Air Quality Matters Too
Poor outdoor air quality often translates into compromised indoor environments. Closing windows during peak smog hours, using air purifiers, and maintaining clean living spaces can significantly reduce indoor pollution levels.
“Indoor air quality can be just as concerning,” notes Dr. Choudhary. He recommends frequent vacuuming, washing pet bedding regularly, and using humidifiers to counteract dryness caused by polluted air. Avoiding incense sticks, cigarette smoke, and harsh chemical cleaners further helps protect pets’ sensitive respiratory systems.
Warning Signs Pet Parents Should Never Ignore
Air pollution-related illness in pets doesn’t always look dramatic at first. Persistent coughing, wheezing, sneezing, nasal discharge, red or watery eyes, lethargy, or changes in appetite are all red flags. Skin irritation and excessive scratching can also signal environmental stress.
“If these symptoms persist, veterinary attention should be sought promptly,” stresses Dr. Choudhary. Early intervention can prevent minor irritations from turning into serious respiratory or systemic issues.
Proactive Care Is No Longer Optional
With air pollution becoming a recurring seasonal reality, especially in urban India, proactive pet care is essential. Adjusting routines, improving indoor environments, and staying alert to behavioural and physical changes can make a significant difference.
As Dr. Choudhary puts it, “Protecting pets from air pollution today is as important as vaccinations and regular health check-ups. Awareness and timely action are key to keeping them healthy year-round.”
