I have a very energetic Labrador who needs daily walks to burn off some energy. I'm looking for someone reliable and experienced with dogs, preferably someone who can take him for a 1-hour walk in the afternoons. He is friendly but very playful, so someone who enjoys active dogs would be ideal. The walks would be around my neighborhood in London, and I would need this service three times a week. Please be comfortable handling a strong dog and have your own transportation if possible.
