Guide dogs are also a widely known type of working dog, serving as the eyes for blind people. After strict training, guide dogs can assist blind individuals in going out. They bring great convenience to the lives of the blind. They are accustomed to constraints such as collars, guide harnesses, and other accessories, understand many commands, can lead the blind to walk safely, and will guide their owners to stop to avoid danger when encountering obstacles or needing to turn.

　　So which breeds are suitable to become guide dogs? Most memorable to everyone is the touching movie "Guide Dog Xiaoq". The breed of Xiaoq is Labrador. In fact, many dog breeds can be trained as guide dogs, but in China, the first choice is Golden Retrievers and Labradors. So why can Golden Retrievers and Labradors be selected as guide dogs?

　　Firstly, guide dogs undergo strict training from a young age. To become a qualified guide dog, a dog needs to face comprehensive tests. First, in choosing the breed, it must have a moderate size, convenient for pulling; for example, guide dogs must be intelligent, have good memory, and be easy to train; guide dogs must have strong resistance to distractions and not be affected by external stimuli; guide dogs must have a gentle temperament and be loyal to their owner, etc. Golden Retrievers and Labradors exactly meet these conditions.

　　Firstly, both Golden Retrievers and Labradors are very intelligent. In a ranking list of dog intelligence, Golden Retrievers rank fourth and Labradors rank seventh, making them the brains of the dog world. Moreover, they have high obedience and are easy to train; secondly, the gentle personalities of Golden Retrievers and Labradors grant them strong resistance to distractions, allowing them to effectively reject temptations, and their loyalty to their owners adds to their suitability as guide dogs; thirdly, the moderate size of Golden Retrievers and Labradors makes it very convenient for owners to lead them. Friendly and enthusiastic about work, they make people more willing to entrust guide duties to them.

　　Once guide dogs are trained and wear a special harness, they enter work mode. At this time, their energy is focused on obeying the owner's commands and they are no longer distracted by surrounding events. Once the harness is removed, they are actually no different from normal family pet dogs. They also need to play, exercise, be petted, act cute, and interact emotionally. But even the best dogs can be tempted by food. So when you meet a working guide dog on the street, do not disturb it, do not talk to it to attract its attention, and do not tease it with food. Otherwise, the guide dog will be distracted and its work performance will be affected.

　　Dogs are good friends of humans, not only as pets but visible in all aspects of life. Moreover, they are loyal, brave, and kind, so we should cherish and care for them.
