🐶 Heat Stroke in Dogs Inside Cars: A Hidden Danger
Despite common assumptions, even a running car with air conditioning does not guarantee safety for dogs—especially large, double-coated breeds.
📍 Tragic Case in Ohio: Bruno, the Newfoundland
• On July 4, 2025, in Ohio, Bruno, a 4‑year‑old Newfoundland, suffered fatal heat stroke in a running SUV with A/C on and windows cracked.
• On a CBS news broadcast Dr. Brandon Michels of Sugarcreek Veterinary Clinic explained that airflow in larger vehicles is uneven, often concentrated at the front, failing to cool dogs in the backseat properly .
• Breeds with thick or double coats, like Newfoundland, Husky, Bernese Mountain Dogs, and others are particularly vulnerable, even when a vehicle appears to be climate-controlled.

Why A/C Can Be Misleading
1. Insufficient airflow to the backseat or cargo area – front vents don’t always reach the rear.
2. Ventilation drops significantly when the car is idle—without motion, AC efficiency plummets.
3. Trapped heat in cargo spaces or kennel-style crates, where hot air accumulates faster.

Broader Risk: Dogs Indoors Without Cooling
• In Maine, multiple dogs recently died from heat stroke indoors without air conditioning, proving that ANY enclosed, warm space can turn deadly  .
• For pets both indoors and in vehicles, cooling and continuous airflow are essential.
⸻
🔴 Recognize Heat Stroke Early in Dogs
Early signs: heavy panting, drooling, dry gums.
Progression: trembling, uncoordination (“drunken” gait), vomiting, diarrhea.
Severe cases: collapse, seizures, unconsciousness; all are life-threatening.
At-home response:
• Move to shade or cool area.
• Offer lukewarm water (not cold).
• Apply cool, damp towels to body.
• DON’T leave unattended—seek vet care immediately and don’t delay!
Final Thoughts
Bruno’s heartbreaking death is a potent reminder: heat stroke can happen fast and under deceptive conditions. To protect our canine companions—from puppies to giants—owners must stay vigilant, ensure proper ventilation and hydration, and never assume automatic safety just because a car or home is running.
🔔 If you notice any sign of heat distress in a pet, start cooling measures immediately and get to a veterinarian without delay. It’s not just about comfort—it’s about survival.
