The term 'Dog Warnings' can refer to the vocalizations that a dog makes in order to communicate with its owner or other animals. Two common examples of these vocalizations are snarls and GROWLS. Snarls are low, throaty sounds that are often accompanied by bared teeth and a wrinkled nose. GROWLS are deeper, more aggressive sounds that indicate a higher level of aggression. Both of these vocalizations are used by dogs to warn their owners or other animals to stay away.
