Summer in southeastern Massachusetts and Rhode Island brings plenty of opportunities for outdoor fun, but it also increases the risk of heatstroke in pets.
Heatstroke can become life-threatening in minutes. Unlike people, dogs and cats cannot regulate their body temperature as effectively. Once their body temperature rises too high, serious complications including organ damage, clotting abnormalities, and even death can occur.
The good news? Heatstroke is often preventable, and recognizing the warning signs early can save your pet’s life.
For additional warm-weather precautions, travel advice, and common seasonal hazards, read our Guide: Summer Pet Safety & Travel Tips.
In this guide, you’ll learn:
- Signs of heatstroke in dogs and cats
- What to do if your dog has heatstroke
- When overheating becomes an emergency
- Which pets are most at risk
- How to prevent heat-related emergencies
What Is Heatstroke in Pets?
Heatstroke occurs when a pet’s body temperature rises above a safe range and they can no longer cool themselves effectively.
Medically, heatstroke is generally diagnosed when a pet’s body temperature reaches approximately 105.8°F or higher and is accompanied by neurologic abnormalities. However, temperatures above normal, especially those exceeding 104°F, are already concerning and may rapidly progress to heatstroke.
Without prompt treatment, overheating can lead to:
- Organ failure
- Abnormal clotting
- Respiratory distress
- Neurologic injury
- Death
What Causes Heatstroke in Dogs and Cats?
Common causes include:
- Being left in a parked car, even for a few minutes
- Exercising during hot weather
- High humidity
- Limited access to shade
- Lack of fresh water
- Vigorous play during the hottest parts of the day
Even temperatures that feel comfortable to people can quickly become dangerous for pets.

- Restlessness
- Weakness or lethargy
- Bright red gums

These signs may indicate that your dog is overheating and needs immediate cooling and veterinary evaluation.
Advanced Signs of Heatstroke in Dogs (Medical Emergency)
As heatstroke progresses, symptoms become more severe.
Emergency signs include:

If your pet develops any of these symptoms, seek emergency veterinary care immediately.

Heatstroke in Cats Symptoms
- Rapid breathing or panting
- Drooling

Cats may also hide when they don’t feel well, which can make symptoms harder to recognize.
What to Do If Your Dog Has Heatstroke
If you suspect your pet is overheating, act immediately.
Step 1: Move Your Pet to a Cool Area
Bring your pet:
- Indoors
- Into an air-conditioned space
- Into shade if indoors isn’t available
Step 2: Start Cooling Gradually
Use cool water, not ice-cold water.
Focus on:
- Belly
- Paw pads
- Armpits
- Groin area
Use fans if available.
The goal is gradual cooling, not rapid chilling.
Step 3: Offer Small Amounts of Water
If your pet is alert and able to swallow:
- Offer small amounts of cool water
- Do not force drinking
- Do not give water if your pet seems confused or unable to swallow normally
Step 4: Seek Emergency Veterinary Care Immediately
Even if your pet appears to improve, serious internal damage may already be occurring.
Heatstroke should always be treated as a veterinary emergency.
