Does having an Obedience title guarantee a good temperament?
No. Earning an Obedience title demonstrates that the dog was trainable by the person who taught them the Obedience exercises. By itself, this certainly does not mean that anyone else could train the same dog or that the dog is more reliable than another dog without an Obedience title. In evaluating the temperament of an Akita, trainability is certainly one important factor but you also have to look at the instinctive behaviors which the dog displays. For example, I know of an Akita who was trained for the Obedience ring and did quite well at earning his title yet he repeatedly tried to attack other dogs without provocation and often growled at people when he wasn’t in the Obedience ring. I certainly would not consider this dog to have a good temperament although he does have an Obedience title.
