Actually I want to get a Rhodesian Ridgeback next time, they too are a strong dog and are considered one of the smartest breeds.
I saw one in our neighborhood recently. A beautiful dog...many of them, especially those from S.A. and Rhodesia carry Boerboel genes, and they were often used by farmers in tandem with the Boerboel. On a hunt the Ridgebacks would race out to corner the prey (a jackal or some other farm animal killing pest)and would hold the prey there until the farmer and the slower, but bigger, boerboels could arrive on the scene. Reputed to be a very smart dog...but it needs lots of exercise.
