Heatstroke, also known as hyperthermia, occurs when a pet’s internal body temperature exceeds 105 degrees Fahrenheit. Normal body temperature for dogs is generally around 101 to 102 degrees Fahrenheit. When this threshold is crossed, it can lead to severe health issues and can be fatal if not treated promptly.

Dogs are particularly susceptible due to their limited ability to cool themselves, primarily through panting and minimal sweating through their paws, reports the American Kennel Club.

 

Early Signs of Heatstroke

Recognizing the early signs of heatstroke in dogs is crucial for prompt treatment. Symptoms include heavy panting, rapid breathing, excessive drooling, and dry or sticky gums, The Sacramento Bee reports.

The dog’s skin may feel very hot to the touch, and their heart rate can be elevated. As the condition progresses, more severe symptoms such as seizures, lethargy, disorientation, and even collapse may occur.

 

Causes of Heatstroke

• High Ambient Temperatures: Dogs left in poorly ventilated spaces or in cars can quickly overheat. The temperature inside a parked car can rise dramatically within minutes, leading to dangerous conditions, according to the American Kennel Club.
• Physical Condition: Dogs with thick fur, short noses (like pugs and bulldogs), and those suffering from certain medical conditions are more prone to heatstroke. Overweight and elderly dogs are also at higher risk, reportsMemphis Veterinary Specialists.
• Lack of Water: Insufficient hydration can exacerbate the risk of overheating. Always ensure pets have access to fresh water, especially during hot weather, The Seattle Times recommends.
• Exercise: Excessive physical activity during hot weather can lead to heat exhaustion and heatstroke, especially in unacclimated or unfit dogs, reports Global News.

How to Treat Heatstroke

If you suspect your pet has heatstroke, immediate action is required. Move your dog to a cooler environment right away. Wet their fur with cool (not cold) water and use a fan to help lower their body temperature. Offering cool water to drink is also essential. However, avoid forcing them to drink, as it can lead to aspiration pneumonia, Memphis Veterinary Specialists reports.

Monitoring your pet’s temperature with a rectal thermometer can offer accurate results. Aim to reduce their body temperature to around 103 degrees Fahrenheit before transporting them to a veterinarian for further treatment, American Kennel Club recommends.

Veterinary Care for Heatstroke

At the veterinary clinic, treatment for heatstroke includes intravenous fluid therapy to rehydrate and replace essential minerals. Vets will also monitor for secondary complications such as kidney failure, neurological symptoms, and abnormal blood clotting, The Seattle Times reports, while It’s critical to continue observing the pet after initial treatment since complications can arise hours or even days later.

Preventing Heatstroke

• Never Leave Pets in Cars: Even with windows cracked, the temperature inside a vehicle can become dangerously high very quickly.
• Provide Adequate Shade and Water: Ensure pets have access to shaded areas and plenty of water, especially during outdoor activities.
• Limit Exercise: Avoid strenuous exercise during the hottest parts of the day. Opt for early morning or late evening walks when temperatures are cooler.
• Use Cooling Aids: Cooling mats, pet-safe popsicles, and body wraps can help keep your pet comfortable during hot weather.

Recognizing High-Risk Breeds

Certain breeds are more susceptible to heatstroke due to their physical characteristics. Brachycephalic breeds, like pugs and bulldogs, have restricted airways making it harder for them to cool down, The Sacramento Bee reports.

Long-haired breeds and those with dark coats also absorb more heat and should be monitored closely during warm weather. Heatstroke in pets is a serious condition that requires immediate attention. Recognizing the early signs and taking swift action can save your pet's life. Always ensure your pet is well-hydrated, has access to shade, and avoid exposing them to extreme heat.

If in doubt, consult with your veterinarian for advice tailored to your pet's specific needs.
