The Amazing Dobermans (1976) - Byron Chudnow.

Fred Astaire, James Franciscus and Barbara Eden star in the family friendliest installment of these charismatic, sleek-limbed  daredevil dobermans! Happily, these kooky canine capers playfully continue in a barking mad fashion in The Amazing Dobermans. The bustling circus location is fun, with Franciscus and Eden making for amiable, wise-cracking protagonists. Director Chudnow certainly nose that you most certainly can teach an old dog new tricks! Even in in its more cutesy form, there's snout quite like these dynamic Dobermans!
