I myself have a black labrador and I would love to take your dog on a walk too! His name is Alfie and he is 11 years old. Unfortunately, my lovely dog is still in England, however I will love your dog just as much as my own! I live in the centre of Madrid so I can get to you easily to pick up your furry friend! I also speak Spanish, so don't worry if English is an issue for you. I am available week days from 6pm (or 5pm if you are close to my work on calle galileo) and any time on the weekends too, but preferably mornings or afternoons. Please contact me if you are looking for a friendly, reliable dog walker.
