God-forbid a dog under a Rover pet/home sitters care bit them (for any reason even if its never bitten anyone or ever showed aggression). Whether its barely a bite or serious enough is there any protection for: 1) the owner (if all steps were taken for warning/prepping sitter) What constitutes properly warning/prepping? 2) the sitter (to have medical needs taken care of). Who is liable to cover medical fees to sitter? Is owner responsible/ in trouble for the bite? Can dog be penalized for the bite? Does rover get involved in any way?
