I want to start a dog walking business, can I do it without a business license? It wont be like a professional business or anything just something small like around the neighborhood. Would I need a license just to walk about maybe 5 dogs at a time MAX!!!! I'm also wondering if you can start at 12? I would probably make about 20 flyers maybe 50 and go to the houses around the neighborhood I'm almost positive I don't need a license but I just want to double check!!! Shanks or thanks!!!
