Dogs are often referred to as man’s best friend, but they can do more than just play fetch with balls or Frisbees. Many of the dog breeds we keep as pets today were originally bred to perform specific tasks. From search-and-rescue to guarding flocks of sheep, working dogs have assisted humans in some amazing ways throughout history.
One of the most recognizable categories of working dogs is the service dog, which includes guide dogs for the blind, mobility-assistance dogs and seizure-detecting dogs. Service dogs are trained to keep their handlers safe and behave well in all kinds of situations, both in public and at home. Golden retrievers and Labrador retrievers are two breeds well-suited for this type of work.
Search-and-rescue dogs are employed to locate people who have gone missing in different situations. Whether it’s skiers buried by avalanches or hikers disappearing in natural areas, these dogs use their acute sense of smell and hearing to track down humans in need. Saint Bernards, Leonbergers and bloodhounds are several breeds whose keen noses make them excellent search-and-rescue dogs.

Herding dogs are perfect for the job of controlling livestock. Any breed with “shepherd” or “collie” in their name, like the Australian shepherd dog or Border Collie, is bred to be alert, energetic and agile enough to keep animals like sheep and cattle safe from threats. They also work closely with their handlers to keep herds moving in an organized fashion.
These few jobs only scratch the surface of dogs’ true capabilities. There are other dogs suited for therapy jobs, hunting, military and police work or guarding homes. Whatever their job, though, one thing all dogs have in common is their unbreakable bond with humans.
狗狗往往被稱為人類最好的朋友，但牠們所能做的不只是用球或飛盤玩你丟我撿。如今被我們當成寵物的許多品種的狗狗，一開始都是被培育來執行特定任務的。從搜救行動到看守羊群，歷史上，工作犬以一些驚人的方式幫助了人類。
工作犬其中一個最為人所知的類別即是服務犬，包含專為盲人服務的導盲犬、協助行動的犬隻，以及能夠偵測癲癇的狗狗。服務犬被訓練來保護領犬員的安全，並幫助他們在所有狀況中都能恰當反應，在公共場合或是家中皆然。黃金獵犬和拉布拉多犬是兩種很適合這類工作的犬種。
搜救犬被用來尋找在不同狀況下失蹤的人。不管是被雪崩所掩埋的滑雪者，或是在自然區域中消失的健行者，這些狗狗用牠們敏銳的嗅覺和聽覺來追蹤需要協助的人類。聖伯納犬、蘭伯格犬和尋血獵犬這些品種靈敏的鼻子讓牠們成為優秀的搜救犬。
牧羊犬很適合控制家畜的工作。任何名字中有「牧羊（shepherd 或 collie）」的品種 —— 像是澳洲牧羊犬或邊境牧羊犬 —— 都被培育成足夠機警、有活力且敏捷，以保護像是綿羊或牛隻等動物的安全，使牠們免受威脅。牠們也與其領犬員密切合作，以讓牧群以有組織的方式移動。
這一些工作僅僅觸及狗狗真正能力的表面而已。還有其他狗狗適合治療工作、狩獵、軍警工作，或是保護家園。不過不管牠們的工作是什麼，所有狗狗都有一個共通點，那就是牠們與人類之間堅不可摧的連結。

Photographer Franziska Stuenkel likes to take spontaneous urban shots, so she needs a nimble camera that is ready to go when inspiration strikes: her German-made Leica M11. “I have to be very quick and discreet,” said the Berlin-based artist who captures reflections of people walking past windows, their contours merging with the shapes behind the glass. Stuenkel’s compact Leica is the perfect camera for the job, the 51-year-old told AFP. Famous for its pocket-sized and retro-style devices, the Leica brand is celebrating a milestone as it marks 100 years since its first commercial camera was presented to the public. The
Picture a 45-foot-long animal with a 5-foot-long skull and 3-foot-long arms. It may not seem strange until you realize that a human with those proportions would be 6 feet tall with 5-inch arms. Although the Tyrannosaurus rex went extinct 65 million years ago, the mystery of its unusual body __1__ has fascinated scientists for over a century. Barnum Brown, the paleontologist who first discovered T. rex fossils, initially found it hard to believe that the tiny arms belonged to such a __2__ creature. One of his colleagues speculated that the short forelimbs might have been used to hold the
As global travel rebounds following the COVID-19 pa ndemic, the longstanding issue of overtourism has returned stronger than ever. Throughout 2024, numerous popular destinations worldwide struggled with tourist numbers that far exceeded their infrastructural and environmental capacities. Not only does this surge congest streets and pollute landscapes, but it also endangers cultural sites and disrupts the daily lives of residents. In response to the growing problem of “overtourism,” various nations have adopted diverse strategies, some of which have sparked controversy. Venice, Italy, has not hesitated to take bold action; since 2024, the city has implemented one of the
Dogs’ noses are incredibly keen. They can even detect changes in cortisol levels in human sweat and breath. Known as the “stress hormone,” cortisol increases when humans are under pressure. Recent research indicates that the smell of human stress can influence a dog’s behavior and emotions. In the study, human volunteers were exposed to the stressful tasks of preparing and delivering a speech on the spot and then solving math problems. __1__ Researchers collected sweat and breath samples from the volunteers on pieces of cloth during both their stressful and restful states. Meanwhile, other researchers worked with 18
