I realize this is an old thread, thanks for your patience. I have a question. My father has a legitimate Fila Brasileiro. I am looking for a female puppy with which to breed with him. I've located a seller who claims that he has two Fila females. However, the parents are not his. The parents are supposedly papered Fila's, and I've been told he can supply copies of the paperwork for me at time of purchase of a puppy. I'm new to the puppy purchasing game. What pitfalls am I facing in this scenario? How often do private sellers fake papers for Fila pups? He is selling for $500 each, and the puppies DO resemble a Fila (hips are higher than the shoulders, fine featured face/nose with bloodhound jowels, and athletic builds).
