Guide dogs are specially trained animals that assist individuals with visual impairments. These dogs help their handlers navigate their surroundings safely by avoiding obstacles, stopping at curbs, and finding entrances. The most common breed used for guide dogs is the Labrador Retriever, but other breeds like the Golden Retriever and German Shepherd are also popular. The training process for guide dogs is extensive and can take up to two years. They learn various commands and how to respond to different situations. Once trained, these dogs provide not only mobility assistance but also companionship and emotional support to their handlers.
