A dog walker is a person who is hired to take dogs out for exercise and bathroom breaks. They typically walk dogs in neighborhoods, parks, or other safe areas. This service is especially helpful for pet owners who may not have enough time to walk their dogs due to work or other commitments. Dog walkers can provide various services, including daily walks, playtime, and feeding. They often work with multiple dogs at once and may use leashes, harnesses, and other equipment to ensure the safety of the dogs. Many dog walkers also offer additional services like pet sitting or training, making them a valuable resource for pet owners.
