What’s wrong with a dog that grunts when it sleeps?

Dogs may dream when they fall asleep, and during the dreaming process dogs will grunt, while there may be shaking limbs, twitching and other situations, which is normal for owners not to worry. The owner should observe the dog for symptoms such as depression, loss of appetite, vomiting and diarrhoea, and take the dog to the vet for examination and treatment in a timely manner.
