Do you know anything about a Fila? Do you know anything about the parents of the litter? I don't know much about the Cane. However, a Fila is just not for anyone. They are very hard dogs, that if they have proper temp. will not accept strangers and needs an experienced handler. It is hard to tell what their temp will be when they are young. It can take a year or two for them to mature into it. So just because it is a sweet puppy now does not mean it will be in a couple of years. Unless, this is the type of dog you want I would proceed with caution.
I own 2 and they are the best dogs I have ever owned but they are a big responsibility and we have had to change our lifestyle just to own them.
