How far away a dog can hear depends on the dog. Dogs' range of hearing is approximately between 50Hz and 45kHz.
An assistance dog is a dog trained to aid or assist a person with a disability. Many are trained by a specific organization, while others are trained by their handler (sometimes with the help of a professional trainer).
A dog park is a park for dogs to exercise and play off-leash in a controlled environment under the supervision of their owners. These parks have varying features, although they typically offer a 4' to 6' fence, separate double-gated entry and exit points, adequate drainage, benches for humans, shade for hot days, parking close to the site, water, tools to pick up and dispose of animal waste in covered trash cans, and regular maintenance and cleaning of the grounds. Dog parks may also offer wheel-chair access, a pond for swimming and a separate enclosure for small dogs.
Dog communication refers to movements and sounds dogs use to send signals to other dogs and other creatures (usually humans). Dog communication comes in a variety of forms and is part of the foundation of dog social behavior.
Dogs use certain movements of their bodies and body parts and different vocalizations to express their emotions: they move their ears, eyes, eyebrows, mouth, nose, head, tail and entire body, as well as barks, growls, whines and whimpers, and howls.
In journalism, a human interest story is a feature story that discusses a person or people in an emotional way. It presents people and their problems, concerns, or achievements in a way that brings about interest, sympathy or motivation in the reader or viewer.
Human interest stories may be "the story behind the story" about an event, organization, or otherwise faceless historical happening, such as about the life of an individual soldier during wartime, an interview with a survivor of a natural disaster, a random act of kindness or profile of someone known for a career achievement.
