Aggression toward people:
Beenie is a sweetheart and would go home with anyone.

Frankie plays 'the part'.
He barks and growls at everyone but when introduced to the stranger he turns into butter.

Aggression toward other dogs is another story:
Beenie makes friends but Frankie would get himself in trouble.

Your dogs are probably all a bit aggressive because of Screech.
They are following his lead. I hope they never hurt anyone.
