Dogs like to hide under the bed to sleep usually because they are timid or because it is cool under the bed, so you need to prepare a comfortable kennel for the dog. It is best to place the kennel in a hidden corner so that the dog feels more secure. .
Tips:
If the weather is hot, you can put a cooling pad for the dog in the kennel, which can have a cooling effect; and it is best not to use it when the dog is sleeping. Disturb it to avoid being frightened.
