Looking for someone experienced with large dogs to assist with walks for my 110 lb Great Pyrenees. He is friendly but has a tendency to roam and may try to run off if given the opportunity, so experience handling strong, independent dogs is important. I would attend the walks as well in case extra help is needed. Availability would be on an as-needed basis, primarily around 12 noon, 3:30 PM, and 9 PM. Please reply with your experience handling large breeds and your general availability.
