Symptoms of Heatstroke in Dogs and Cats
Know the Warning Signs
Before It Becomes an Emergency
Warm weather gives us plenty of opportunities to enjoy time outdoors with our pets, but high temperatures can also put dogs and cats at risk of overheating. Heatstroke occurs when a pet's body temperature rises to a dangerous level and they are unable to cool themselves effectively.
Heatstroke can develop quickly and may lead to serious complications if left untreated. Recognizing the early warning signs and knowing when to seek emergency veterinary care can help protect your pet when temperatures rise.
Understand the Warning signs in Dogs and Cats
Common Signs of Heatstroke in Dogs
Dogs primarily cool themselves by panting, which can become less effective during very hot or humid weather. Certain dogs may also be more susceptible to overheating because of their breed, age, weight, coat, activity level, or underlying health conditions.
Signs of heatstroke in dogs may include:
- Excessive or unusually heavy panting
- Rapid breathing
- Excessive drooling or thick, sticky saliva
- Bright red or unusually pale gums
- Weakness or extreme tiredness
- Difficulty standing or walking
- Confusion or disorientation
- Vomiting or diarrhea
- Loss of coordination
- Collapse
- Tremors or seizures
As heat-related illness becomes more severe, dogs may become increasingly weak, unresponsive, or unable to stand. Vomiting, diarrhea, abnormal behavior, seizures, and collapse can all occur with serious heat-related illness.
Signs of Heatstroke in Cats
Although cats may be less likely than dogs to develop heatstroke, they can still become dangerously overheated—particularly when trapped in a hot, poorly ventilated area or exposed to high temperatures for an extended period.
Because cats do not normally pant the way dogs do, open-mouth breathing or panting in a cat should always be taken seriously.
Other possible warning signs include:
- Rapid breathing or panting
- Excessive drooling
- Restlessness or unusual behavior
- Weakness or lethargy
- Bright red, pale, or abnormal-looking gums
- Vomiting
- Difficulty walking or standing
- Confusion
- Tremors or seizures
- Collapse or loss of consciousness
If your cat is breathing with their mouth open, appears distressed, or suddenly becomes weak after being exposed to heat, seek veterinary attention immediately.
Tips on Preventing Heatstroke in the Summer
Taking a few precautions during warmer weather can help reduce your pet's risk of overheating.
Always provide access to fresh water and shade, avoid strenuous exercise during the hottest part of the day, and never leave a pet unattended in a parked vehicle. On especially hot or humid days, keep outdoor activities shorter and watch closely for changes in your pet's breathing, energy level, or behavior.
Knowing what is normal for your pet can help you recognize when something is wrong.
