Dog walking for your loved one

I've had animals around me since I was little. Back home I have two pets - 11 years old labrador Tola and 9 years old British cat Maximus. I used to spend my free time volunteering in a local animal shelter. Now, while I'm a final year university student I am looking to casually walk other people's dog from my neighbourhood. My lifestyle does not allow me to own a dog myself at the moment, however, I would happily pet and walk dogs for other busy people. I can use parks around Lenton and Wollaton and other green areas that Nottingham has to offer. I am available most weekdays and the weekends for either short or long walks.
