We all know that dogs stick out their tongues generally to dissipate heat, so why do dogs stick out their tongues when sleeping? In fact, there are good and bad reasons for this, and it is best for the owner to learn to distinguish between them.
1. Relaxation
When the dog feels at ease and comfortable in the living environment and is in an extremely relaxed state, the dog will stick out its tongue unconsciously. This is a normal phenomenon, so the owner does not need to worry too much.
2. Heat dissipation
Dogs' sweat glands are not well developed and they mainly dissipate heat through their tongues and foot pads. Therefore, when the indoor temperature is relatively high or they have exercised strenuously before going to bed, dogs will stick out their tongues to dissipate heat. If this is the case, the owner can lower the temperature by lowering the temperature of the dog's environment and giving the dog water to drink.
3. Hanging Tongue Syndrome
If a dog has often stuck out its tongue since childhood, it may suffer from hanging tongue syndrome. Sick dogs often cannot control their tongues, causing their tongues to stick out for a long time. This not only affects the dog's eating, but may also damage the tongue. Therefore, if the owner suspects that the dog has hanging tongue syndrome, it is best to take the dog to the pet hospital for examination and treatment in time.
