My experience with 3 filas at the same time was, they are naturally aloof with strangers, even as small puppies ( 10 weeks). As they get older they continued this trait and often seemed that they were unaware of what was going on in the room."DO NOT BE FOOLED"!They are very aware and although mine were never aggressive, they were very protective!!! Sudden moves by visitors cause them to come to attention, if someone stands and approaches you while you are still sitting they will stand & begin to approach if you don't command them not to. Mine never advanced on anyone in the house just because they didn't know them.They were not aggressive, but very conscious of the fact that their job was to protect! They were the same way with children, very protective.
