With Filas health issues are at a minimum, but the closer you stay to the working lines the better. Show lines, especially imports from Brazil, are having more health issues, in large part, I think, because of the corruption in the show breeding there. Some of the show breeders are infusing the lines with more Great Dane and Bull Mastiff blood to get a dog that is, among other things, easier to handle in the ring with less temperament, and with those two breeds, you get health issues.
