Sweet is important to me right now because of the environment I'm in. I live in a townhouse in the suburbs and have a small yard. Out of necessity, I must take Zeus to parks, Petco, crowded places, walking trails, etc., to be sure he gets exercise. And with my close neighbors and frequent joggers passing by, an overly protective or loud dog is not a good thing.
But when we buy our country house and land sometime next year, I do not want a sweet dog. I want a dog with good guarding instinct and a strong sense of "duty". Hence, we're probably getting a fila.
