...The Fila Brasileiro is an excellent estate guardian. It does not hide its dislike towards strangers, but these dogs are not disqualified from the show ring for showing aggression to the judges. Such aversion is instinctive in Filas, so much so that the Brazilian breed standard advises judges not to touch the dog. However, the FCI standard allows for disqualification of excessively aggressive dogs, mainly when the owner doesn't have enough control to show them in public areas. The breed is renowned for their faithfulness to family and friends, but this is not a breed for everyone. The Fila needs a confident, experienced, savvy owner who is aware of the breed's innate tendencies. Filas are not well suited to busy household which entertain many guests, as they do not interact well with strangers. The Fila is a natural guardian breed.

Filas bond strongly with their immediate families and show extreme loyalty and protectiveness towards them. They live to protect their loved ones, including children and other pets. Very few will accept strangers. Many Filas will never tolerate any stranger. Despite their aversion towards strangers they are excellent family dogs, devoted to the children in their family...

This sounds like my American Eskimo! She is great with the family but *hates* everyone else and barks like crazy when anyone tries to come in this house.

The American Eskimo Dog was originally bred to guard people and property and, therefore, is territorial by nature and a valiant watchdog. They are not considered an aggressive breed. But, due to the breed's watchdog history, American Eskimos are generally quite vocal, barking at any stranger who comes within close proximity to their owners or their owner's territory.
I had to google. Those are georgous dogs. My girls are about 130 and 120 lbs. You wouldn't believe it by looking at them but they extremely are agile and athletic. Serious as heart attacks and meaning business when around strangers. They should be secured and not running loose however.
