When dogs sleep, we can’t help but see how the dogs sleep. Sometimes when we see their tongues sticking out, we really feel ridiculous. In fact, there are three reasons for dogs to stick out their tongues when sleeping:

1. Relaxation: Dogs feel at ease and comfortable in their living environment. When sleeping, all parts of their bodies are in a relaxed state. After the tongue and mouth muscles are relaxed, they will unconsciously stick out their tongues. For dogs, sticking out their tongue while sleeping is the best way to relax.

But don't pull its tongue, as accidents may occur or leave a shadow on the dog.

2. Work: The dog's tongue is still working when he sleeps, especially in the hot summer. The dog will spit out its tongue and evaporate saliva when sleeping, causing the tongue to cool and release heat in the blood vessels.

3. Pay attention to it, it may be a disease: the dog's teeth or lips are deformed, and it is impossible to completely block the tongue, causing the tongue to be exposed. Some dogs also develop tongue symptoms after tongue injuries, which will become more serious as they get older. You need to take your dog to see a pet dentistry.
