There is no need to spank a dog when it growls. They usually make this sound when they feel scared. You need to comfort the dog in time so that it does not get scared. If the dog growls because it is protecting food, Huh, then parents should correct this habit in time, otherwise it may cause some trouble to parents in the future.

Tip:

When a dog wants to attack a person, it will generally lower its body, expose its fangs, and roar. Parents should stop and correct this habit in time when they discover it.
