Kennel cry is a term used to describe the various vocalizations that dogs make. The most common kennel cries are HOWL (4 letters), ARF (3 letters), BARK (4 letters), YAP (3 letters), YIP (3 letters) and YELP (4 letters). Howling is usually associated with wolves and is a long, drawn-out sound that can be heard from a great distance. ARF is a short, sharp BARK that is often used to alert others of danger. Barking is a more common sound that dogs make and is usually used to express excitement or to alert their owners of something. Yapping is a high-pitched sound that is often used to get attention. Yipping is similar to yapping but is usually shorter in duration. Yelping is a loud, sharp sound that is often used to express pain or fear.
