Los Angeles Pet Emergency Guide: Wildfires, Heat, and Urban Dangers

Coyote Attacks: LA's Growing Urban Threat

Coyote attacks on pets have increased 300% in Los Angeles over the past decade. They're no longer limited to hillside neighborhoods — coyotes are now regularly spotted in Hollywood, Silver Lake, Santa Monica, and even Downtown LA.

Highest-risk times: Dawn and dusk (crepuscular hunters), but urban coyotes increasingly hunt at night under streetlights. Small dogs under 25 lbs and outdoor cats are primary targets.

Highest-risk areas: Griffith Park perimeter, Runyon Canyon, Laurel Canyon, Topanga Canyon, and any neighborhood bordering the Santa Monica Mountains.

Warning signs of a coyote bite: Puncture wounds (often on neck, back, or abdomen), bleeding, shock, and internal injuries that may not be immediately visible. Coyotes carry rabies, distemper, and parasites.

What to do: Apply pressure to bleeding wounds with a clean cloth. Do NOT try to clean deep wounds. Drive to the emergency vet immediately. Even small puncture wounds can hide severe internal damage. Our emergency team will assess for internal bleeding, administer antibiotics, and update rabies prophylaxis.

Wildfire Smoke: The Invisible Emergency

LA's fire season now runs nearly year-round, and wildfire smoke is a serious respiratory emergency for pets — especially birds, cats, and brachycephalic dogs. During the 2025 fire season, our LA emergency vet saw a 400% increase in respiratory cases.

Why pets are more vulnerable: Dogs and cats breathe faster than humans, inhaling more particulates per pound of body weight. Birds have extremely efficient respiratory systems that make them hypersensitive to smoke.

Warning signs: Coughing, wheezing, nasal discharge, eye redness and tearing, lethargy, loss of appetite, and difficulty breathing. Cats may hide and stop eating — a subtle but serious sign.

What to do during poor air quality: Keep pets indoors with windows closed. Run air purifiers if available. Limit outdoor time to bathroom breaks only. If your pet develops breathing difficulty, coughing that won't stop, or blue-tinged gums, seek emergency vet care immediately.

Rattlesnakes in the Hollywood Hills

Southern Pacific rattlesnakes are common throughout the LA hills and canyons, and bites spike from April through October. Hiking trails in Runyon Canyon, Griffith Park, and the Santa Monica Mountains are prime snake territory.

What makes LA snake bites unique: Many LA dog owners hike with their pets off-leash, increasing encounter risk. The warm climate means snakes are active for a longer season than in most US cities.

Warning signs: Sudden yelping, swelling (especially on the face or legs), two puncture wounds, pain, weakness, and difficulty breathing.

What to do: Keep your pet still and calm. Carry them to your car. Do NOT apply a tourniquet or ice. Drive to our emergency vet — we stock CroFab antivenin. Consider the rattlesnake vaccine for dogs who frequently hike LA trails (it buys extra time but does NOT replace emergency treatment).

Heat Emergencies: Year-Round in LA

Unlike cities with distinct seasons, LA's heat is a year-round threat. Santa Ana winds can push temperatures above 100°F even in October and November, catching pet owners off guard.

LA-specific dangers: Black asphalt in parking lots and sidewalks absorbs extreme heat. Beach sand can burn paw pads. Cars parked in LA sun reach lethal temperatures in under 10 minutes.

The LA pavement test: At 95°F air temperature, asphalt reaches 140°F. At 100°F, it hits 150°F+. If you can't hold your bare hand on the ground for 5 seconds, your dog can't walk on it.

What to do for heatstroke: Move to AC immediately. Apply cool water to paw pads, belly, and ears. Drive to the emergency vet with AC on full. We treat heatstroke cases daily during summer and Santa Ana events.
