Almost all animals, even Man (the most difficult) can be trained, conditioned and be tamed. Regardless of the natural behavior. I need guard dogs, for this I keep my Filas with a strong temperament and I do not try to condition them in another way. In farms, the behavior of the Fila is and has to be conditioned. During the day, when the stream of workers is more intense, they are left to sleep and conditioned to accept the people passing close by without attacking them. Almost always ignoring them and only warning with a snarl. Keeping distance and serenity. They do not play with the people and they do not attack. If and when they do, the farm, owner or even the worker to whom the dog it is most used to will correct its attitude. The dogs were and are conditioned to do the work and the function they have to perform. I've been to farms in which I could enter during the day and others that I could not even leave the car. (A fact which occurs when the owners are not present ) Recently I went to a farm that had filas but I couldn't get through the gate, not because I was attacked but because the Fila was laying down in the middle of the way to the gate and I did not have courage to step over it. I could only go up to a certain point, not any further. If we want a dog for shows, we can train it for such. If we want a guard dog, let us leave it as it naturally is. It is enough to give them affection and they will protect us. I believe that the Fila can be trained to coexist and that it does not have to be trained for the attack and defense because it is already natural to them. Therefore, coming back to the initial subject, follow the advice and instruction of whom you trust and respect without mixing it up a lot. As for me, if anybody wants something more specific, you can contact me personally so I can send photos of old and recent dogs which I consider Fila, that is, dogs that I would like to have and dogs that I would like that my dogs to look alike. I will do my best to try to help. It is also the correct way to form opinion. Seeing dogs or photos of dogs, not of our breeding, which we consider FILA and to try to obtain some which will look more like them.
