The summer solstice has come and gone which means fun in the sun for you and your pups! And as a responsible dog owner, it’s also a great time to brush up on the dangers of heat-related illnesses. Prolonged exposure to heat can easily result in heat exhaustion, and in the most extreme cases, heat stroke, which can be life threatening. But with a little bit of awareness and preparation, we can ensure that our pups stay safe all summer long.
How Dogs Cool Off
As temperatures soar during the summer months, the risk of heat stress in dogs becomes a significant concern for pet owners. Unlike humans, dogs cannot sweat through their skin to cool down. Instead, they rely on panting and, to a lesser extent, sweating through their paw pads. This limited ability to regulate body temperature makes them particularly susceptible to heat stress and heatstroke, conditions that can have serious and sometimes fatal consequences. Dogs use a similar method by rapidly breathing in air (aka panting) which evaporates the moisture in their mouths, nose, and lungs.
What is Heat Stress & Exhaustion?
Heat stress in dogs occurs when their body temperature rises to dangerous levels and they cannot dissipate the excess heat. This can lead to heat exhaustion and potentially escalate to heatstroke, a life-threatening condition.
The normal body temperature for dogs ranges between 101°F and 102.5°F (38.3°C and 39.2°C). When a dog's temperature exceeds 104°F (40°C), it enters the danger zone, and immediate action is necessary to prevent serious health complications or death.
However, just like sweating is limited in its effectiveness, so is panting. Heat stress and exhaustion occurs when a dog’s internal system becomes overwhelmed by extensive exposure to hot temperatures and/or direct sunlight. Since our dogs are unable to tell us what they are feeling or experiencing, it’s important for dog owners to be aware of the symptoms.
In this comprehensive guide, we will delve into what heat stress is, the signs and symptoms to watch for, and effective strategies to prevent and manage heat stress and exhaustion in dogs.
What Causes Heat Stress?
High Environmental Temperatures: Prolonged exposure to hot weather, especially without adequate shade or water, is a primary cause of heat stress in dogs.
Excessive Exercise: Strenuous physical activity in hot and humid conditions can quickly lead to overheating.
Enclosed Spaces: Leaving a dog in a parked car, even for a few minutes, can be extremely dangerous. Temperatures inside a vehicle can rise rapidly, creating a deadly environment.
Breed and Physical Condition: Brachycephalic breeds (such as Bulldogs, Pugs, and Boxers) with short snouts are more prone to heat stress due to their restricted airways. Overweight dogs and those with underlying health conditions are also at higher risk.
**Age: Puppies and older dogs are more susceptible to heat stress due to their less efficient thermoregulatory systems
Signs and Symptoms Your Dog is Experiencing Heat Stress
Recognizing the early signs of heat stress can save your dog's life. Below are 8 Common symptoms and signs your dog is experience heat stress:
Excessive Panting: While panting is a normal cooling mechanism, excessive and intense panting is a red flag. If this panting becomes excessive and your dog appears uncomfortable, it could be a sign of a heat-related illness.
Drooling or Sticky Saliva: Profuse salivation can indicate that your dog is struggling to cool down. When experiencing heat stress, your dog’s body may also attempt to conserve fluids which may cause a dog’s saliva consistency to become thicker and stickier than usual.
Lethargy: A dog experiencing heat stress may appear unusually tired, weak, or disoriented.
Rapid Heartbeat: An elevated heart rate is a common response to overheating.
Vomiting and Diarrhea: Excess heat can lead to dehydration or electrolyte imbalances which may cause unexpected gastrointestinal issues. These can be signs of severe heat stress and require immediate attention.
Bright Red or Pale Gums: Changes in gum color can indicate overheating and poor circulation. Exposure to heat can cause blood vessels to dilate which may result in reddish-looking gums (compared to their normal pinkish color), an indicator that your dog may be overheating.
Collapse or Loss of Consciousness: In extreme cases, a dog may collapse or lose consciousness, signaling heatstroke. This is, of course, the scariest result that could lead to the most extensive internal damage including blot clots, heart arrhythmias, and organ failure. Get your pet to the vet immediately!
Dizziness, stumbling, or seizures: As heat exhaustion transitions into heat stroke, a dog may become disoriented or experience muscle spasms due to the heat’s impact on their central nervous system.
By learning the early warning signs, you can be aware and intervene before the symptoms become life-threatening.
What do I do if my dog is experiencing heat exhaustion?
Not only is it important to recognize the symptoms of heat exhaustion, but you should also be aware on how to provide first-aid treatment. Swift action is crucial to prevent further complications from occurring, follow these 5 immediate first aid steps:
Move to a Cooler Environment
Hydrate
Cool the Body
Monitor Temperature
Seek Veterinary Care
The goal is to reduce your dog’s temperature. Move away from direct sunlight and take your dog to a shaded area, preferably somewhere cooler and/or well-ventilated (a location with fans or air conditioning is best). Provide fresh water for your dog, but don’t force them to drink since it may cause them to choke or could result in nausea.
Use cool water, damp towels, or even a water hose on areas of their body with a high concentration of blood vessels, such as the groin area, armpits, and paws. Cooling these areas will help dissipate the heat throughout their body. However, DO NOT use ice-cold water or ice packs to cool them down. It might sound counterintuitive, but ice can actually constrict blood vessels which will limit your dog’s ability to dissipate heat. Even worse, your dog can experience shock, or even hypothermia!
Monitor your dog’s temperature with a thermometer. Remember, dogs naturally have a higher temperature than humans which ranges between 99.5°F and 102.5°F (37.5°C to 39.2°C). If your dog’s condition worsens, contact your vet immediately for an emergency visit. However, even if your dog’s condition improves, it is still highly recommended to have a check-up with your vet for a thorough examination.
Preventing Heat Stress is Key!
Preventing heat stress is far better than treating it. Here are some practical steps to keep your dog safe during hot weather:
Provide Ample Water and Shade: Ensure your dog has access to fresh, cool water at all times and a shaded area to rest in when outside.
Limit Exercise: Avoid vigorous exercise during peak heat hours of the day. Early morning or late evening walks are safer options.
NEVER leave your dog in a parked car Even with windows cracked open, the temperature inside a car can become lethal in minutes.
Walk on suitable surfaces: Hot tip (pun intended), if the sidewalk is too hot for your hand, it’s probably too hot for your dog. Avoid scorching your dog’s paws by opting for grassy or shaded paths instead.
Use Cooling Products: Consider using cooling vests, mats, or bandanas designed to help keep your dog cool.
Groom Appropriately: Regular grooming can help manage your dog's coat and prevent overheating. However, avoid shaving breeds with double coats, as their fur provides insulation against both heat and cold.
Monitor Humidity: High humidity levels can make it harder for dogs to cool down through panting. Be extra cautious on humid days.
Recognize High-Risk Conditions: Be mindful of the specific needs of brachycephalic breeds, older dogs, puppies, and dogs with health conditions. They may require extra precautions always take breed and age into consideration.
Special Considerations for Different Dog Breeds
Different breeds have varying levels of susceptibility to heat stress. Here are some considerations for specific types of dogs:
Brachycephalic Breeds: Dogs with short snouts, such as Bulldogs, Pugs, and Shih Tzus, are at higher risk due to their compromised ability to pant efficiently. These breeds should be kept in cool environments as much as possible, and their activity should be closely monitored during hot weather.
Double-Coated Breeds: Breeds like Huskies, Malamutes, and Samoyeds have thick double coats that can trap heat. While it might be tempting to shave these dogs, their fur actually helps regulate their body temperature. Instead, focus on regular grooming to remove excess undercoat and provide ample water and shade.
Working and Sporting Breeds: Dogs such as Retrievers, Border Collies, and German Shepherds are often very active and may not realize when they're overheating. It's important to monitor their activity levels and ensure they take breaks in the shade with access to water.
Long-Term Effects of Heat Stress
Heat stress doesn't just pose an immediate risk; it can also have long-term health implications for dogs. Repeated episodes of heat stress can lead to chronic conditions such as kidney damage, cardiovascular problems, and respiratory issues. It's essential to be vigilant about preventing heat stress to ensure your dog's long-term health and well-being.
Creating a Heat Stress Emergency Plan
Having a heat stress emergency plan can save precious time and make a significant difference in a critical situation. Here’s what to include:
Emergency Contacts: Keep your veterinarian's contact information and the address of the nearest emergency animal hospital readily accessible.
Cooling Supplies: Have a supply of cool towels, a thermometer, and access to cool water.
Travel Precautions: When traveling with your dog, ensure you have a plan for cooling and hydration. Never leave your dog unattended in a vehicle.
Training: Ensure all family members and caregivers know the signs of heat stress and the steps to take in an emergency.
Heat stress is a serious and potentially fatal condition that can affect dogs of all breeds and ages. By understanding the causes, recognizing the signs, and taking proactive measures to prevent overheating, pet owners can ensure their dogs remain safe and healthy during the hot summer months. Always be attentive to your dog's behavior, provide a cool and comfortable environment, and never hesitate to seek veterinary care if you suspect heat stress. With the right precautions, you and your furry friend can enjoy a fun and safe summer together.
