Heatstroke in dogs and cats is a medical emergency. In Cave Creek, where summer temperatures can become extreme and pets may be exposed to intense sun, hot patios, vehicles, garages, hiking trails, or outdoor exercise, overheating can progress from seemingly ordinary panting to a life-threatening illness surprisingly quickly.
If you think your dog or cat may be developing heatstroke, do not wait to see whether the symptoms resolve on their own. Move your pet into a cool environment, begin safe cooling, and contact a veterinary hospital immediately.
During regular business hours, Desert Forest Animal Hospital provides same-day urgent veterinary care and emergency triage in Cave Creek when staffing, current patient volume, and the individual patient’s medical needs allow.
Call before you drive: (480) 488-2010.
For a critically ill pet, a pet that has collapsed, is having seizures, is unresponsive, is having severe difficulty breathing, or requires intensive or overnight treatment, a 24-hour emergency hospital may be the safest destination. Our team can help direct you when possible.
What Is Heatstroke in Dogs and Cats?
Heatstroke occurs when an animal’s body temperature rises to a dangerous level and the body can no longer dissipate heat effectively.
Dogs cool themselves primarily through panting rather than through the extensive sweating mechanism people have. Cats also have limited ability to cool themselves through sweating. When environmental temperature, exertion, humidity, airway disease, or other factors overwhelm those cooling mechanisms, body temperature can rise rapidly.
The American Animal Hospital Association describes heatstroke as a potentially life-threatening condition that can occur when a pet’s temperature rises above normal and normal cooling mechanisms fail.
Cornell University College of Veterinary Medicine notes that prolonged heatstroke can damage organs throughout the body and may contribute to acute kidney injury, abnormal blood clotting, shock, neurologic injury, and other serious complications.
This is why a pet may still need veterinary treatment even if they appear somewhat better after being moved into air conditioning.
Signs of Heatstroke in Dogs and Cats
Early recognition can make a major difference. Warning signs can include:
- Heavy or unusually rapid panting
- Excessive drooling or thick, ropey saliva
- Restlessness or obvious distress
- Seeking shade or refusing to continue walking
- Weakness or marked lethargy
- Very warm skin
- Bright red, pale, or abnormal-looking gums
- Rapid heartbeat
- Vomiting
- Diarrhea, sometimes with blood
- Stumbling or loss of coordination
- Confusion or altered behavior
- Difficulty breathing
- Tremors
- Collapse
- Seizures
- Loss of consciousness
According to both AAHA and the Merck Veterinary Manual, vomiting, excessive panting, drooling, weakness, incoordination, collapse, and neurologic changes are important warning signs of potentially dangerous overheating.
Heatstroke Can Continue to Cause Damage After Your Pet Leaves the Heat
One of the most important things for pet owners to understand is that heatstroke is not simply “being too hot.”
Severe hyperthermia can trigger a cascade of inflammation and injury involving multiple organs. Problems may involve the kidneys, gastrointestinal tract, brain, cardiovascular system, liver, and the body’s ability to clot blood normally.
A pet that appears calmer after cooling may therefore still require examination, laboratory testing, intravenous fluids, monitoring, and additional treatment.
At Desert Forest Animal Hospital, in-house blood work and veterinary diagnostics can help our veterinarian assess sick and injured patients when medically appropriate. Heatstroke patients may require more advanced emergency monitoring or hospitalization depending on the severity of their condition.
What to Do Immediately if You Suspect Heatstroke
If your dog or cat appears overheated:
- Stop activity immediately.
- Move your pet out of direct heat. Get into shade, an air-conditioned building, or an air-conditioned vehicle.
- Call a veterinary hospital immediately. Do not spend 20 or 30 minutes attempting home treatment before seeking help.
- Begin gentle, active cooling. Wet the body with cool or tepid water and increase air movement with a fan or air conditioning.
- Begin transportation to veterinary care. Cooling and transport can occur at the same time.
Do not wait for your pet to collapse before seeking veterinary care.
What to Do on the Way to the Veterinary Hospital
The drive to the hospital is valuable treatment time. You can begin safe cooling while another person drives.
1. Turn the Air Conditioning Up
Use the car’s air conditioning and direct cool airflow toward your pet. Cornell specifically recommends wetting an overheated dog with cool water and placing the patient in front of the vehicle’s air conditioning while traveling to the veterinary hospital.
2. Wet Your Pet With Cool or Tepid Water
If practical, wet your pet’s coat and skin with cool or tepid water. Concentrate on areas where evaporation can occur efficiently, including the body, chest, abdomen, groin, and paws.
For dogs with dense or double coats, make sure the water actually reaches the skin rather than simply wetting the outer coat.
3. Increase Airflow
Evaporation helps remove heat. Use the vehicle’s air-conditioning vents or a fan to move air across the wet coat.
4. Do Not Use an Ice Bath
Do not immerse your pet in ice water or extremely cold water. Current veterinary guidance favors controlled cooling rather than aggressive ice-water immersion.
AAHA advises against ice or very cold water for home cooling, and the Merck Veterinary Manual cautions against immersing an overheated animal in cold water.
5. Do Not Wrap Your Pet in Wet Towels
A wet towel may initially feel cooling, but wrapping an overheated animal can eventually trap body heat and interfere with evaporation.
If you use a wet cloth briefly to apply water, remove it rather than leaving your pet tightly wrapped.
6. Do Not Force Water Into Your Pet’s Mouth
If your pet is fully alert and able to swallow normally, small amounts of cool water may be offered.
Do not force a weak, confused, vomiting, collapsed, or poorly responsive animal to drink. Doing so may increase the risk of aspiration.
7. Call Ahead
If another person is with you, have them call the veterinary hospital while you are driving.
During regular business hours, call Desert Forest Animal Hospital at (480) 488-2010.
Calling ahead allows our team to assess the situation, prepare for your arrival when possible, and advise you if a 24-hour emergency facility would be more appropriate.
8. Drive Safely
Heatstroke is urgent, but a car accident will not help your pet. Use hands-free calling or have a passenger communicate with the veterinary team while the driver focuses on the road.
Should I Take My Pet’s Temperature?
A normal body temperature for a dog or cat is roughly 100–102.5°F, although individual variation occurs.
Heatstroke often involves temperatures above approximately 104–105°F, but do not rely on a thermometer alone to decide whether your pet needs veterinary care.
A pet may already have begun cooling by the time their temperature is checked while still having significant internal injury.
If you already know how to safely obtain a rectal temperature and doing so will not delay transportation, it can provide useful information for the veterinary team. AAHA recommends stopping aggressive active cooling once body temperature reaches approximately 103°F to reduce the risk of overshooting into hypothermia.
Do not delay departure for the veterinary hospital simply to obtain a temperature.
Which Dogs Are at Greater Risk for Heatstroke?
Any dog can develop heatstroke, but some patients require much greater caution.
Higher-risk dogs include:
- Bulldogs
- French Bulldogs
- Pugs
- Boston Terriers
- Boxers
- Other brachycephalic or short-nosed breeds
- Overweight dogs
- Senior dogs
- Puppies
- Dogs with heart disease
- Dogs with respiratory disease
- Dogs with laryngeal paralysis or airway problems
- Dogs with thick or dark coats
- Dogs exercising intensely in hot weather
Cornell’s summer heat-safety guidance emphasizes the increased risk faced by brachycephalic dogs, overweight pets, older dogs, and patients with underlying cardiac or respiratory disease.
Can Cats Get Heatstroke?
Yes. Heatstroke is discussed more frequently in dogs because dogs are often exercising outdoors, riding in vehicles, hiking, walking, and spending extended time outside with their owners, but cats can also develop dangerous hyperthermia.
Indoor cats may be at risk in a home, garage, enclosed patio, sunroom, or other poorly ventilated area that becomes excessively hot.
Open-mouth breathing or panting in a cat is particularly concerning and deserves prompt attention, especially when accompanied by weakness, drooling, vomiting, abnormal behavior, collapse, or other signs of illness.
Common Heatstroke Scenarios in Cave Creek
Living in the Sonoran Desert creates environmental risks that deserve additional planning.
Heat-related emergencies may occur after:
- Midday or afternoon walks
- Hiking during warm weather
- Running beside a bicycle
- Playing fetch for too long
- Being left outdoors without adequate shade
- Being confined in a garage or enclosed patio
- Being left in a parked vehicle
- Unexpected air-conditioning failure
- Heavy exertion in a brachycephalic dog
- Outdoor activity during high humidity or extreme heat
In Cave Creek, the temperature at ground level can also become much hotter than the reported air temperature. Hot pavement and artificial surfaces may contribute additional thermal stress and can injure paw pads.
Never Leave a Pet in a Parked Vehicle
A vehicle can become dangerously hot very quickly, even when outdoor temperatures do not initially seem extreme.
Cracking the windows does not make a parked vehicle safe.
If your pet cannot accompany you inside your destination, the safest choice during warm Arizona weather is usually to leave them at home in a reliably air-conditioned environment.
What Happens at the Veterinary Hospital?
Veterinary treatment depends on the severity of the patient’s condition and how much systemic injury has occurred.
Evaluation may include:
- Immediate physical examination and triage
- Body-temperature monitoring
- Heart and respiratory assessment
- Blood-pressure evaluation
- Blood glucose and electrolyte assessment
- Complete blood count
- Blood chemistry testing
- Assessment of kidney and liver function
- Evaluation for abnormal clotting
- IV fluid therapy
- Oxygen when indicated
- Medication for gastrointestinal or neurologic complications
- Continued active cooling when appropriate
- Hospitalization and intensive monitoring
Not every heat-exposed pet requires every test or treatment. Veterinary care should be individualized according to the patient’s examination findings, temperature, neurologic status, cardiovascular stability, laboratory results, medical history, and response to initial treatment.
Learn more about in-house blood work and diagnostics at Desert Forest Animal Hospital.
When Heatstroke Requires a 24-Hour Emergency Hospital
Severe heatstroke can require intensive monitoring, repeated laboratory testing, oxygen therapy, blood-pressure support, treatment for abnormal clotting, transfusion therapy, or overnight hospitalization.
Desert Forest Animal Hospital is not a 24-hour emergency hospital.
During our regular business hours, we provide urgent veterinary evaluation and emergency triage and may treat or stabilize appropriate patients when our current capacity and the patient’s condition allow.
For a critically ill patient, we may recommend proceeding directly to—or transferring your pet to—a 24-hour emergency and specialty hospital.
Our goal is not to keep every emergency in our hospital. Our goal is to help each pet reach the right level of care as quickly and safely as possible.
Fear Free Care During an Emergency
A heatstroke patient may already be frightened, nauseated, weak, painful, disoriented, or having difficulty breathing.
Dr. Quinn Bauer, DVM is a Fear Free Certified veterinarian, and our team incorporates Fear Free veterinary principles whenever the patient’s medical condition allows.
That may include thoughtful positioning, minimizing unnecessary restraint, watching body language, addressing pain and distress, and using sedation when it provides safer or more humane care.
In a true emergency, however, life-saving stabilization takes priority. A critically ill animal cannot safely wait for gradual acclimation when immediate treatment is required.

Frequently Asked Questions About Heatstroke
Is heatstroke an emergency in dogs?
Yes. Suspected heatstroke should be treated as a veterinary emergency because elevated body temperature can damage multiple organs and complications may continue even after a dog begins to cool.
Can a dog recover from heatstroke at home?
A dog that has progressed beyond mild overheating should not simply be observed at home. A pet may appear improved while internal complications are still developing. Contact a veterinarian promptly whenever heatstroke is suspected.
Should I put ice on a dog with heatstroke?
Avoid ice baths and very cold-water immersion. Current veterinary guidance generally recommends controlled cooling with cool or tepid water combined with airflow and prompt transport to veterinary care.
Should I cover my overheated dog with wet towels?
Do not wrap an overheated animal in wet towels for an extended period. Wet wrapping can interfere with evaporation and trap heat. Applying cool water directly to the body while providing airflow is generally preferable.
Can I give my dog water during heatstroke?
If your dog is fully alert and swallowing normally, small amounts of cool water may be offered. Do not force water into the mouth of a weak, vomiting, confused, collapsed, or poorly responsive pet.
Can cats have heatstroke?
Yes. Cats can develop dangerous heat-related illness, particularly in hot, enclosed, or poorly ventilated environments. Panting or open-mouth breathing in a cat should be taken seriously.
Does Desert Forest Animal Hospital see heat emergencies?
Yes. Desert Forest Animal Hospital provides same-day urgent veterinary care and emergency triage during regular business hours when staffing, case volume, and the patient’s medical needs allow. Because severe heatstroke may require continuous intensive or overnight care, some patients should be treated at a 24-hour emergency hospital.
Suspect Heatstroke? Call Before You Drive
If your dog or cat is panting excessively, weak, vomiting, stumbling, confused, collapsing, or showing other signs of possible heatstroke, begin safe cooling and seek veterinary care immediately.
