All of my experience is personal from having a wonderful Rottweiler in my life for 13 years! Therefore I can walk big dogs happily, and I have walked my friends small dogs many times. I still have my old dogs lead and treat bag so I can provide those if needed. I have a couple years experience of medicine administration in both tablet and liquid form, which with a rottweiler took a lot of quick thinking to trick her into swallow them for 2 years! As for my availability, I do work and therefore my availability will change with my rotas. Also I do not drive so as long as you live close enough to a bus route I will be able to get to your home!
