Cowering in fear, Pete and Jerry heard the snarl of an unknown animal while walking in the haunted forest.

The snarl of the vicious dogs made the neighbors aware that they were not friendly.

As the patrons would pass the exhibit at the San Diego Zoo, the tigers would snarl in their direction.

At first the wolf’s upper lip would raise and expose its sharp teeth, and then the sound of its snarl would signal danger.

It began as a low growl and rose to a snarl when the dog witnesses the attack on its owner.
