Bull Terriers are pit-bull/bull types. However, unlike some breeds, they have had the aggression and untrustworthiness bred out. Regardless of their heads, they are better dogs than their cousins. Same applies to Bulldogs, and Boston (Bull/dog) Terriers. Proof that breeding with a purpose can remove that aggression.
