Growling is when an animal makes a low, rough sound, usually because it's feeling scared or threatened. It's like a loud rumble in its throat.
When someone says that a dog is growling, they often mean that the dog is showing aggression or trying to protect itself. For example, if you're petting a dog and it suddenly starts growling, it might be saying "leave me alone!" The sound can be low and menacing, but also sometimes just a bit of a grumble. If you know an animal well, you might recognize its growl as a sign that it's feeling anxious or scared, rather than actually angry.
To utter a deep guttural sound, as an angry animal; to give forth an angry, grumbling sound.
Example: The dog growled at me as I walked past.
A sustained instance of growls or guttural noises.
Example: The growling from her stomach told us she was hungry.
