Heat precautions for pets.

In Southern California, heat-related emergencies aren’t limited to scorching summer days. Even a warm afternoon in spring can turn dangerous for dogs – especially active breeds or flat-faced companions. At BluePearl Irvine, our emergency medicine team treats heatstroke cases every year, and many could have been avoided with earlier intervention.

If you’re walking, hiking, or playing outdoors with your dog in Irvine, this guide will help you spot the warning signs of heatstroke and know exactly what to do if it happens.

What causes heatstroke in dogs?

Heatstroke happens when your dog’s body temperature rises faster than they can cool down – usually above 104°F. Dogs don’t sweat like humans; they cool themselves by panting and through their paw pads. When it’s too hot or humid, that system breaks down.

Common risk factors in Irvine include:

  • Exercise during midday heat
  • Lack of shade or water
  • Hot pavement
  • Flat-faced breeds (e.g., bulldogs, pugs)
  • Leaving pets in parked cars – even briefly

Symptoms of canine heatstroke.

Many pet owners don’t recognize the early signs of heatstroke until it’s progressed into a true emergency.

Watch for signs of a pet emergency, including:

  • Excessive, rapid panting
  • Bright red gums or tongue
  • Vomiting or diarrhea
  • Weakness or collapse
  • Seizures
  • Disorientation or glazed eyes

If you see any of these signs, don’t wait – begin cooling efforts and head to your nearest emergency vet immediately.

Immediate first aid steps.

If you suspect heatstroke and you're not near BluePearl Irvine:

  1. Move your dog into shade or AC immediately
  2. Offer small sips of cool (not cold) water
  3. Use wet towels on their belly, armpits, and paws
  4. Avoid full immersion in cold water (this can cause shock)
  5. Head to the ER while cooling continues

 

How we treat heatstroke at BluePearl Irvine.

When you arrive, our emergency team starts triage right away. Most dogs need:

  • IV fluids
  • Oxygen support
  • Cooling protocols
  • Bloodwork and monitoring for organ damage

In some cases, heatstroke leads to clotting issues, kidney failure, or neurological damage, which is why fast action is everything.

How to prevent it in the first place.

  • Walk early or late – not mid-day
  • Always bring water
  • Avoid long hikes on hot days
  • Use cooling vests or shaded gear
  • Never leave pets in a car, even with the windows cracked

Heatstroke in dogs – FAQ for pet owners in Irvine.

Yes – it doesn’t take a blazing summer day for heatstroke to occur. Even moderate temperatures, especially in spring or early fall, can be risky. Dogs are more sensitive to heat than people realize, particularly during exercise or if they’re left in warm environments without airflow.

Dogs overheat when their bodies can’t cool down fast enough. Unlike humans, dogs don’t sweat. They rely on panting and some cooling through their paw pads. If it’s too hot or humid – or they’re exerting themselves too much – their internal temperature can rise to dangerous levels (over 104°F), putting them at risk.

Any dog can overheat, but those at higher risk include:

  • Brachycephalic (flat-faced) breeds like Bulldogs and Pugs
  • Dogs exercised during the hottest parts of the day
  • Pets without access to shade or water
  • Dogs walking on hot pavement
  • Pets left in parked cars, even for short periods

Early symptoms can be subtle but escalate quickly. Be alert for:

  • Heavy or rapid panting
  • Red or darkened gums
  • Lethargy or unsteady walking
  • Vomiting or diarrhea
  • Confusion or disorientation
  • Seizures or collapse in advanced stages

If your dog is showing any of these signs, start cooling them down and seek emergency care immediately.

Take action right away:

  1. Move your dog to a shaded or air-conditioned area
  2. Offer small amounts of cool water to drink
  3. Place damp towels on areas like the belly, armpits, and paws
  4. Avoid dunking your pet in cold water – it can worsen the situation
  5. Transport your pet to an emergency vet as quickly as possible

Don’t wait for symptoms to improve on their own – time is critical.

Upon arrival, your dog will be assessed immediately. Emergency care may include:

  • Intravenous fluids to stabilize temperature and hydration
  • Oxygen therapy if breathing is affected
  • Cooling procedures to safely lower body temperature
  • Lab work to assess organ function and potential complications

In severe cases, we may also monitor for internal issues like kidney damage or blood clotting problems.

Prevention is key. Here’s how to reduce your dog’s risk:

  • Walk early in the morning or after sunset when it’s cooler
  • Always carry fresh water on walks or hikes
  • Stick to shaded paths and avoid asphalt when possible
  • Consider cooling gear like vests or reflective harnesses
  • Never leave your dog in a car – even for a few minutes

Yes, we’re open 24/7 and equipped to handle heat-related emergencies any time of day or night. If you suspect heatstroke, don’t delay – bring your pet in immediately.
