Overheating in dogs
As summer approaches, it is important to know how to keep our loyal four-legged friends cool. Overheating in dogs can lead to serious health problems and even death. Overheating in dogs, also known as heatstroke, occurs when a dog's body is unable to dissipate heat, making it impossible to regulate body temperature. Some dogs tolerate heat better than others. This depends on factors such as breed, coat thickness, and color. Dogs with dark coats often handle heat less well than those with lighter coats; dogs with short snouts also tend to struggle more with heat than those with longer snouts.
How does overheating occur in dogs?
Overheating in dogs happens when a dog's body cannot release heat to regulate its body temperature. This can occur when dogs are exposed to high temperatures and/or high humidity, such as during a heatwave. A dog can also overheat due to excessive physical activity, like during a walk or exercise in warm conditions. Dogs have a harder time losing heat than humans do. Dogs do not have sweat glands and can only sweat through their tongues and paw pads. They try to lose heat by panting heavily. The fact that dogs cannot really sweat is not the only factor increasing the risk of overheating; the following factors can also raise the risk:
- Age: older dogs often have less efficient cooling mechanisms than younger dogs
- Overweight: excess weight can hinder a dog's ability to cool down
- Brachycephalic breeds: dogs with short snouts, such as bulldogs or boxers, often have difficulty breathing and can overheat more quickly
- Certain medical conditions: some conditions, like heart and lung problems, can impair a dog's ability to cool down.
Symptoms of overheating in dogs
Overheating can develop very quickly in dogs. It is important to take immediate action if a dog shows one or more of the following symptoms:
- Excessive panting
- Feeling warm / elevated temperature
- Drooling
- Confusion / loss of coordination
- Collapsing
- Diarrhea or vomiting
- Shock or unconsciousness
How to recognize a life-threatening situation from overheating in dogs?
The situation can quickly become life-threatening if you do not act fast enough when a dog is overheated. Often, you can recognize a dog suffering from overheating by a blue tongue (on the underside and sides) and a lethargic/sluggish dog. The dog is then in heat shock. If you notice symptoms of heat shock, it is crucial to immediately move the dog to a cool place and start cooling it down. It is important to cool the dog evenly and not too quickly. Do not pour buckets of ice-cold water over the dog; instead, place a wet cloth over the dog and keep it wet to maintain coolness. If a dog remains in shock for too long, it can die. If you suspect a dog is overheated and in shock, contact a veterinarian immediately!
Preventing overheating in dogs
Prevention is always better than cure. There are several measures you can take to reduce the risk of overheating in your loyal companion:
- Provide enough shade and water: When your dog is outside, make sure there is plenty of shade and water available. Provide a shady spot in the garden or choose a walk in a wooded area where the dog can cool down. Ensure the dog always has access to fresh water.
- Limit physical activity: When temperatures are high, it is better to limit your dog's physical activity. Plan walks or exercise sessions in the morning or evening when it is cooler.
- Never leave your dog alone in the car: It is absolutely essential never to leave a dog alone in a car, even with the windows open. Temperatures inside a car can rise rapidly and lead to overheating in no time.
- Keep a close eye on your dog during heatwaves: During a heatwave, when temperatures are high, it is important to monitor your dog closely. Keep the dog in a cool, well-ventilated house and provide plenty of water.
- Avoid trimming the coat: In summer, it is better not to trim your dog's coat because the coat provides protection from the sun.
- Swim instead of play: Avoid vigorous play with your dog in high temperatures. It is better to take your dog swimming to keep it cool.
- Do not walk on asphalt or tiles: Tiles and especially asphalt can become very hot in summer. Dog paws are not resistant to this, and the paw pads can get severely burned. Try to have your dog walk on shady ground or grass as much as possible on hot days.
It is important to remember that overheating in dogs can happen quickly, so it is best to take precautions and be alert to the symptoms. By taking the right preventive measures, you can avoid serious health problems or even the death of your dog.
