A dog walker is a person who is hired to take care of dogs by walking them, usually when their owners are busy or unable to do so. This service helps ensure that dogs get the exercise they need, which is important for their health and well-being. Dog walkers often work with multiple clients and may walk several dogs at once, depending on their experience and the needs of the pets. Many dog walkers offer additional services, such as feeding, playing, or providing companionship for the dogs. They may also keep an eye on the dogs' behavior and health during walks. Some dog walkers are self-employed, while others work for pet care companies. This profession is popular in urban areas where many people have busy lifestyles and may not have time to walk their dogs regularly.
