 Additionally, before a dog can compete for an SchH1, it must pass a temperament test called a B or BH ("Begleithundprüfung", which translates as "traffic-sure companion dog test").The B tests basic obedience and sureness around strange people, strange dogs, traffic, and loud noises.A dog that exhibits excessive fear, distractibility, or aggression cannot pass the B and so cannot go on to schutzhund.
