As a prerequisite, before a dog can compete for IGP1, it must pass a temperament test called a BH-VT (usually called just "BH"). The BH-VT tests basic obedience and confidence around strange people, strange dogs, traffic, bicyclists, joggers, loud noises, and briefly tethered alone (such as tethering the dog to a post while its owner goes out of sight into a shop). A dog that exhibits excessive fear, distracted behaviors, or aggression will not pass the BH-VT and so cannot go on to IGP level 1. BH-VT is the exception to the rule of earning only one title at an event; a dog may be awarded a BH-VT along with one other level 1 title.
