PORTLAND, Ore. (KOIN) — Hazardous air quality can be dangerous for pets too.

DoveLewis Veterinary Emergency & Specialty Hospital said pet owners should limit outdoor time. Puppies and older dogs are especially at risk, as well as those with asthma, bronchitis and dogs with rounder faces and shorter noses.

Signs of respiratory stress include:

Difficulty breathing

Unusual or excessive coughing, sneezing, vomiting or loss of appetite

Swelling or inflammation of the mouth, eyes, skin or upper airway

Open-mouthed breathing, especially in cats

Weakness/lethargy

Uncoordinated walking/unable to stand

DoveLewis also recommends having preparing your pet for evacuation. This means gathering their medical records, food, bowls medication, leash and collars.
