Canine sounds are the vocalizations made by dogs. These sounds can range from a low growl to a high-pitched yelp. The most common canine sounds are woofs, BAYS, arfs, and barks. Woofs are short, deep, and loud sounds that are often used to express excitement or alertness. BAYS are long, drawn-out sounds that are usually used to express distress or alarm. Arfs are short, sharp sounds that are often used to express surprise or joy. Barks are short, sharp sounds that are usually used to express warning or aggression.
