It's common to see dogs with their tongues hanging out temporarily—often they're cooling down or picking up on interesting scents. However, if your dog’s tongue hangs out all the time and won’t go back in, it could be a sign of Hanging Tongue Syndrome (HTS). This can be uncomfortable and requires careful care to ensure your dog’s well-being.
Dogs pant and stick out their tongues primarily to regulate body temperature, as the tongue’s broad surface area helps release heat. Additionally, dogs extend their tongues when sniffing strong or appealing smells to engage the Jacobson’s organ, which detects pheromones and scent particles.
This behavior is usually controlled and temporary—the dog can pull its tongue back inside at will. Frequent tongue protrusion without other signs can be normal and harmless.
Hanging Tongue Syndrome happens when a dog physically cannot pull its tongue back into the mouth. This causes the tongue to dangle constantly, even when the dog is resting or sleeping. Over time, this exposure can dry and crack the tongue, cause soreness, increase infection risks, and even lead to sunburn in exposed areas.
Several underlying factors can trigger HTS, including:
While HTS currently has no known cure, you can help your furry friend stay comfortable with these care tips:
If you notice that your dog’s tongue has started to hang out frequently or they show signs of discomfort, difficulty eating, or foul breath, seek veterinary advice quickly. Vets will assess oral health and neurological function to discern treatable issues or design a management plan to improve your dog’s life quality.
Responsible pet owners recognize health changes early and seek timely care. When considering breeds prone to HTS, such as brachycephalic dogs, choose reputable breeders who focus on health and ethical breeding standards to reduce inherited problems.
In conclusion, if your dog’s tongue stays out persistently, it might be Hanging Tongue Syndrome. This condition mostly relates to dental health, breed anatomy, or injury. Prompt recognition and supportive care help keep your dog happy and comfortable for years to come.
