Why do dogs sometimes lie down on the ground to sleep?

Dogs lie on the ground to sleep. Generally, dogs lie on the ground to sleep because they are too hot. The ground is relatively cooler, so there is nothing wrong with it.

Unless the dog often sleeps on the ground, lacks energy, and is too lazy to move, this situation indicates that there is something wrong with the dog's body.

In addition, dogs’ sleep patterns are generally the same as those of humans.

For example: if the owner’s life pattern is to stay up during the day and go out at night, the dog will also reverse its sleeping habits day and night, but this will fundamentally disrupt the dog’s biological clock. For the sake of the dog’s health , this kind of owners should consider changing their life patterns.
