A dog that moans like crying while sleeping may be having a nightmare, or the dog feels cold, and its body hums instinctively. Parents can wake the dog up or keep it warm, so that the dog will stop whining. Well, dogs’ sleep is generally divided into light sleep and deep sleep. Dogs who sleep lightly wake up easily.

Tip:

No matter how old the dog is, it spends most of the day sleeping. Parents should not disturb them at will when they have nothing to do.
