IMO,that is where lifestyle comes in. I do not have alot of company. On the rare occasion I am social, I will go out but other than the kids and grandkids, I don't have much in the way of company as a rule. I don't think that if you have a very busy household with a lot of visitors, that the Fila would be the dog for you. As far as a leash goes, I don't let Ruger out without a leash and am not a believer in any dog being off leash away their home except for the places designated for such and the truth is, I don't take my dog (nor have I ever) to off leash events because I don't trust other people. I'm still a newbie and I don't own a Fila yet but Lifestyle and housing are two of the first things that need to be considered, IMO. I definitely agree that Fila's are not the dogs for everyone but I believe they are the perfect fit for me. When I want to be social with a dog,I have my sweet Ruger for that. LOL
While I might like to be a little more the recluse at this point in time it isn't possible, especially with a family our size and with young kids now I will have a LGD I think at some point in the future but will have a place to put the dog up when we expect company, otherwise the area will be posted and we will be back in the woods so there shouldn't be anyone just happening up the long driveway. I think you are doing great!
