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 mornings or early afternoons. He is friendly but quite strong, so someone comfortable handling a lively dog would be ideal. Regular walks 3-4 times a week would be great. Please let me know if you have experience with large breeds and your availability.
