And to elaborate a bit further.
The Fila Brasileiro is NOT an aggressive breed. It is a
defensive breed. There is a significant difference between the two!
Generally, as a breed, the Fila is the Mastiff recognized as being most affable with other animals. They are a herding dog as well as a guardian, after all. Some Bulls and Olde English are fine with other dogs, but as a general rule, they aren't - as a breed - dependably so. Charley's Bulls just tolerated the other dogs in the family . . .
It takes a great deal of intelligence, patience, humor and love to live with Filas . . . and if you have an inflated sense of your own dignity it won't last long, lol! Just ask Filarotten and Buckshot
Oh, and they do seem to have a 'thang' for redheads . . .
