How old is your son? And you do realise if he gets a Fila there is a very real probability he wont be able to have friends over to your house in about a years time? Not unless you isolate the dog when you have visitors? There wont be any knocking on the door and coming in to play, unless of course like I say you isolate the dog? I dont own a Fila but if it were me I wouldnt choose that as a childs first furry best friend, these are a serious hard breed. Im sure Dogman will chime in here and give you the low down on owning one of these AMAZING but not to be taken lightly breeds. Im not saying you cant or shouldnt have one, dont get me wrong, but a Fila for a first time childs dog??
