The term 'ANGRY DOG'S SOUND' can be described by four different words: GROWL (5 letters), GNARL (5 letters), SNARL (5 letters), and GRR (3 letters). A GROWL is a low, guttural sound made by an animal, usually to express anger or aggression. GNARL is a similar sound, but with a more raspy quality. SNARL is a loud, harsh sound, often accompanied by bared teeth. Finally, grr is a short, sharp sound, usually used to express displeasure. All of these sounds are typically associated with an angry dog.
