Dog Walker is an app where you can find all those around you who want to help you when you don't have time for walking your dog.
You don't have a dog? No problem! Create a profile and tell the dog owners that you want to babysit their dog - either when they don't have the time in everyday life, or when they are on holiday.
Whether you want to walk/babysit dog can be or not free of charge, is up to you.
