Haze contains fine particles that can irritate the eyes and airways. Dogs, cats, rabbits, birds and other companion animals may be affected, especially those with existing heart or breathing problems.

1. Check the air before heading out

Singapore’s National Environment Agency (NEA) publishes 1-hour PM2.5 readings for immediate outdoor decisions and the 24-hour Pollutant Standards Index (PSI) forecast for planning ahead. These are public-health indicators, not pet-specific safety thresholds. If air quality is poor, take a cautious approach for your pet. Check haze.gov.sg or the myENV app before walks.

2. Keep walks short and gentle

When haze level rises, swap long runs and active play sessions for brief walks. Avoid strenuous exercise outdoors, and choose quieter, less exposed locations when possible. Keep cats and small animals indoors, and postpone non-essential outdoor activities.

3. Make indoor air more comfortable

Close windows and doors when outdoor air quality is poor. If available, use a correctly sized air purifier with a HEPA filter. Avoid cigarette smoke, incense, scented sprays and other indoor irritants. Ensure rooms are well ventilated again when outdoor conditions improve.

4. Offer water and indoor enrichment

Keep clean water readily available, and encourage normal drinking. Replace outdoor exercise with food puzzles, scent games, gentle training or age-appropriate play. Provide pets with a comfortable resting area and monitor their appetite and energy.

5. Take extra care with vulnerable pets

Older animals, young pets, brachycephalic breeds such as pugs and bulldogs, and pets with diagnosed respiratory or cardiac conditions may need additional precautions. Birds and small mammals can be particularly sensitive to airborne irritants. Ask your veterinarian for individual guidance if your pet has a medical condition.

6. Know when to call the vet

Contact a veterinarian if your pet develops persistent coughing, wheezing, eye irritation, unusual lethargy, reduced appetite or changes in breathing. Open-mouth breathing in a cat, pronounced breathing difficulty, collapse or blue-tinged gums are emergencies: seek veterinary care immediately. Do not give human medicines or fit an improvised mask without veterinary advice.

A little planning helps everyone breathe easier. Check current air readings, reduce outdoor exposure when conditions worsen and keep your pet comfortable indoors. When in doubt, your veterinarian can help you decide what is safest for your animal.
