My fiance has decided that she wants to start a dog walking business here in Florida. We've already discussed her forming an LLC to protect her from liability but she also mentioned having dog walking insurance (like this). I'm a software developer and have only ever freelanced or started a business in that field so I don't know much about dog walking businesses.
Is this dog walking or pet business insurance necessary for starting a dog walking business? If it's not required, is it recommended and/or beneficial to have it or is it just a wasted expense?
