"Wenn die Zunge sich krümmt, ist es Zeit, sofort anzuhalten" - der Warnsignal des Hundetrainers.

A dog trainer has raised concerns about heatstroke in pets during the summer months, highlighting a key warning sign that owners should watch for. The alert comes from Max, a well-known canine trainer with over 170,000 followers on TikTok under the handle mk9plus. In a widely shared video, he explains how the position of a dog’s tongue can indicate whether it is suffering from overheating. As temperatures rise, dogs, like humans, are vulnerable to heat-related illnesses. However, unlike humans, who can communicate their discomfort through speech, dogs rely on physical signs to signal distress. Max emphasizes that while panting is normal for dogs in hot weather, there are specific indicators that suggest a more serious condition. He notes that dogs lose heat primarily through panting, using their large tongues to dissipate body heat effectively. The trainer points out that a dog's ability to regulate its body temperature differs significantly from that of humans. Dogs lack sweat glands distributed across their skin, which means they depend almost entirely on panting to cool down. According to Max, the amount of time a dog's tongue remains outside its mouth is directly related to how much heat it is experiencing. The longer the tongue stays exposed, the higher the risk of overheating. However, the most critical sign, according to the trainer, occurs when the dog’s tongue begins to curl inward. This change in behavior signals that the animal is struggling to manage its body temperature and may be approaching a dangerous situation. Max warns that this is the moment when immediate action is necessary. He advises pet owners to stop the activity and allow the dog to rest, as continued exposure could lead to heatstroke. Heatstroke in dogs can develop quickly and is potentially life-threatening. Symptoms include excessive panting, drooling, weakness, and a high body temperature. If left untreated, it can result in organ failure and even death. Max stresses that some breeds are particularly susceptible to heat, such as brachycephalic dogs like bulldogs and pugs, which have shorter nasal passages and struggle to breathe efficiently in warm conditions. Pet owners are urged to monitor their dogs closely during periods of extreme heat. It is recommended to provide access to shade, fresh water, and avoid exercising during peak hours. Signs of heat exhaustion should not be ignored, and prompt intervention is crucial. While many dogs may tolerate mild heat, others can deteriorate rapidly, making early recognition of symptoms essential. In addition to recognizing the curled tongue as a red flag, other warning signs include lethargy, vomiting, and collapse. These symptoms require immediate veterinary attention. Max encourages pet owners to educate themselves on these indicators and take preventive measures to keep their animals safe during the warmer months. His advice aligns with broader recommendations from animal welfare organizations, which emphasize the importance of vigilance and proactive care for pets in hot climates.
